Malaria case management, consisting of early diagnosis and prompt effective treatment, remains a vital
component of malaria control and elimination strategies. The National Treatment Guidelines ensures that
the best evidence based treatment is provided for management of malaria in the country.
Recommendations:
All cases of suspected malaria should have a parasitological test (microscopy or Rapid diagnostic test (RDT))
to confirm the diagnosis. Therefore, it is necessary to scale-up malaria diagnostics facilities to ensure the
feasibility of parasitological diagnosis. Both microscopy and RDTs should be supported by a quality assurance
programme.
Treatment of Malaria UNCOMPLICATED MALARIA
First line treatment
Uncomplicated P. falciparum malaria: Treat children and adults with uncomplicated P. falciparum malaria
(including infants, lactating women and pregnant women in their second and third trimester; except pregnant
women in their first trimester) with recommended ACT (artemether + lumefantrine) for 3 days, with giving a
single dose of 0.25 mg/kg bw Primaquine to P. falciparum patients (except pregnant women, infants aged <
6 months and women breastfeeding) to reduce transmission. Testing for glucose-6-phosphate
dehydrogenase (G6PD) deficiency is not required.
Infants weighing < 5 kg with uncomplicated P. falciparum malaria should be treated with recommended ACT
(AL) at the same mg/kg bw target dose as for children weighing 5 kg.
P. vivax malaria
Blood stage infection: Treat all patients with P. vivax malaria with Chloroquine.
Preventing relapse: To prevent relapse, treat P. vivax malaria in children and adults (except pregnant women,
infants aged < 6 months, women breastfeeding) with Primaquine as following
In patients with normal G6PD level: consider giving a 14-day course of Primaquine base at 0.25 mg/kg bw
daily.
In patients with mild-to-moderate G6PD deficiency: consider preventing relapse by giving Primaquine base
at 0.75 mg/kg bw once a week for 8 weeks, with close medical supervision for potential Primaquine-induced
hemolysis.
In patients with known sever G6PD deficiency: Primaquine is contraindicated and must not be given.
When G6PD testing is not available: consider preventing relapse by giving Primaquine base at 0.75 mg/kg bw
once a week for 8 weeks, with close medical supervision for potential Primaquine-induced hemolysis.
SUMMARY
2
In female patients: In the absence of quantitative testing, all females should be considered as potentially
having intermediate G6PD activity (mild-to-moderate deficiency) and given the weekly dose of Primaquine
with close medical supervision.
Primaquine is contraindicated in pregnant women, infants aged < 6 months and breastfeeding women
Clinically diagnosed malaria
It is strongly recommended to parasitologically confirm all cases with microscopy or RDT and then treat them
based on parasitological confirmation. Only in exceptional cases where parasitological confirmation is not
available (nor microscopic neither RDT) the patient can be treated based on clinical sign and symptoms, if
any other cause was not found.
Clinical cases should be treated with Chloroquine and patient should be referred to facility for confirmation
of diagnosis and follow-up treatment.
Second line treatment
Quinine should be used as second line treatment when treatment failed with first line. Quinine can be given
as: (10mg salt/kg orally three times daily) plus Doxycycline (3.5mg/kg once a day) or Clindamycin (10mg/kg
twice a day); all drugs to be given for 7 days. All cases must be parasitological confirmed before treatment.
Note: NMLCP has plan to test the therapeutic efficacy and safety of (Di hydro artemesinine + Piperaquine) in
the country to introduce this ACT as a second line therapy for uncomplicated confirm malaria cases.
Treating severe malaria
Health Post level: The Community Health Workers (CHWs) at the Health Post (HP) level, should be trained
on major signs of sever malaria and they should refer any sever malaria case to the health center/or hospital
for proper diagnosis and treatment.
Health center level: At health centers (BHC, CHC, mobile team, SHC) where complete treatment of severe
malaria is not possible, all severe malaria patients (adults and children) should be given the initial single
intramuscular dose of Artesunate (as pre-referral treatment) and then refers the patient to an appropriate
facility for further care. Where intramuscular Artesunate is not available; use artemether in preference to
Quinine.
Hospital level: Treat adults and children with severe malaria (including infants, pregnant women in all
trimesters and lactating women) with intravenous or intramuscular Artesunate for at least 24 h and until they
can tolerate oral medication. Once a patient has received at least 24 h of parenteral therapy and can tolerate
oral therapy, complete treatment with 3 days AL (add single dose Primaquine).
Children weighing < 20 kg should receive a higher dose of Artesunate (3 mg/kg bw per dose) than larger
children and adults (2.4 mg/kg bw per dose) to ensure equivalent exposure to the drug.
If parenteral Artesunate is not available, use artemether in preference to Quinine, but if both Artesunate and
artemether are not available, use Quinine for treating children and adults with severe malaria.
3
Malaria treatment in pregnant women
Uncomplicated P. falciparum
First trimester: Treat pregnant women with uncomplicated P. falciparum malaria during the first trimester
with 7 days of Quinine + Clindamycin.
Second and third trimesters: uncomplicated falciparum malaria in the second and third trimesters of
pregnancy should be treated same as common uncomplicated P. falciparum patients with artemether +
lumefantrine 3 days.
Primaquine and Doxycycline are contraindicated and should not be used in pregnancy.
P. vivax malaria: Only blood stage of the infection should be treated with Chloroquine during pregnancy.
Primaquine is contraindicated in pregnant women.
Sever malaria: Treatment of sever malaria in pregnant women is same as treatment of sever malaria in other
patient at each level. Parenteral Artesunate is the treatment of choice in all trimesters. If Artesunate is
unavailable, intramuscular artemether should be given, and if this is unavailable then parenteral Quinine
should be given. Treatment must not be delayed.

Malaria is caused by infection of red blood cells with protozoan parasites of the genus Plasmodium inoculated
into the human host by a feeding female anopheline mosquito. The five human Plasmodium species
transmitted from person to person are P. falciparum, P. vivax, P. ovale (two species) and P. malariae.
Increasingly, human infections with the monkey malaria parasite (P. knowlesi) are being reported from the
forested regions of South-East Asia and particularly the island of Borneo.
In Afghanistan of the four-human species, at present, P. vivax malaria is the most prevalent species
accounting for almost 95% of all parasitological confirmed cases, with less than 5% of total cases attributed
to P. falciparum with a decrease in its proportion over the past years.
In Afghanistan, malaria occurs at altitudes below 2000 meters and its transmission is seasonal from June to
November. The P. falciparum peak is in August to October, a few months after the summer peak of P. vivax.
Many Plasmodium vivax infections relapse during the spring season and this may give rise to a vivax peak
around July. Transmission of P. falciparum, at the edge of its geographical range, is unstable, and can
fluctuate markedly from year to year.
Malaria is a complex disease and its distribution in Afghanistan varies largely from place to place, and is
dependent upon a variety of factors related to parasites, vectors and human populations under different
geographical, ecological and socio-economic conditions. Based on revised National strategic plan from
malaria control to elimination, 2018 – 2022 by using five-year malaria data and combination of available
malaria and environmental information, all districts in Afghanistan were classified into three main strata with
high, medium and low risk of malaria areas:
Stratum Population Districts Criteria
1 6,960,987 123 Those districts with API >1 (confirm
cases) and the TPR above or equal 9%
2 21,738,456 213
Those districts with API (confirm
cases) equal or less than one (<1) and
the TPR below 9%
3 3,392,611 63 Those districts with API =0 and the
TPR zero
INTRODUCTION
8
The goal of National Strategic Plan on Malaria Control and Elimination is to contribute to the improvement
of the health status in Afghanistan through the reduction of morbidity and mortality associated with
malaria with a vision to completely interrupt transmission of P. falciparum by 2020.
Malaria case management consisting of early diagnosis and prompt effective treatment, remains a vital
component of malaria control and elimination strategies. It is one of the key strategic interventions and a
major cornerstone of malaria control and elimination in Afghanistan.
It is recommended to parasitologically confirm all cases of suspected malaria (with microscopy or Rapid
Diagnostic Test, RDT) and then promptly treat according to the National Treatment Guideline (NTG). To
ensure parasitological confirmation at all levels RDTs are introduced through wide-scale implementation of
Community Based Management of Malaria (CBMM) through the extensive CHW network; and awareness of
the general population increased regarding the prompt recognition, appropriate care-seeking behavior and
effective prevention of malaria through community-level and mass media support.
This National Malaria Treatment Guidelines has been revised and updated to ensure that health care workers
are provided with clear evidence-based recommendations on the diagnosis and treatment of malaria adapted
to the specific malaria epidemiology and drug profile in Afghanistan.
10
Prompt, accurate diagnosis of malaria is part of effective Case management. All patients with suspected
malaria should be treated on the basis of a confirmation by microscopic examination or RDT testing of a blood
sample. Correct diagnosis in malaria-endemic areas is particularly important for the most vulnerable
population groups, such as young children and non-immune populations, in whom falciparum malaria can be
rapidly fatal. High specificity of diagnosis will reduce unnecessary treatment with antimalarial drugs and
improve the diagnosis of other febrile illnesses in all settings.
Symptom-Based (Clinical or probable) Diagnosis
Malaria is suspected clinically primarily on the basis of fever or a history of fever. There is no combination of
signs or symptoms that reliably distinguishes malaria from other causes of fever; diagnosis based only on
clinical features has very low sensitivity, specificity and results in overtreatment. The common signs and
symptoms (fever, chills, headache and anorexia) are non-specific and are common to many diseases and
conditions. The appropriateness of particular clinical diagnostic criteria varies from area to area according to
the intensity of transmission, the prevalent species of malaria parasite and other prevailing causes of fever.
The symptoms of malaria which are nonspecific and similar to those of a minor systemic viral illness comprise
headache, lassitude, fatigue, abdominal discomfort and muscle and joint aches, usually followed by fever,
chills, perspiration, anorexia, vomiting and worsening malaise. Many of the key symptoms and signs of
malaria in one area may not be applicable elsewhere. Other possible causes of fever and whether alternative
or additional treatment is required must always be carefully considered. The focus of malaria diagnosis
should be to identify patients who truly have malaria, to guide rational use of antimalarial medicines.
In very exceptional settings where parasitological diagnosis is not possible and other causes of fever are rolled
out, a decision to provide antimalarial treatment can be based on the probability that the illness is malaria.
Parasitological Diagnosis
In all settings, suspected malaria should be confirmed with a parasitological test. The commonly used
confirmatory tests to detect the presence of malaria parasites in blood are microscopy or rapid diagnostic
tests (RDTs). The benefit of parasitological diagnosis relies entirely on an appropriate management response
of health care providers. Antimalarial treatment should be limited to cases with positive tests, and patients
with negative results should be reassessed for other common causes of fever and treated appropriately.
The results of parasitological diagnosis should be available within a short time (< 2 h) of the patient
presenting.
If both the slide examination and the RDT results are negative, malaria is unlikely, and other causes of the
illness should be sought and treated.
Quality assurance of microscopy and RDTs is vital to ensure high sensitivity and specificity of results.
DIAGNOSIS
11
Microscopy
Microscopy not only provides a highly sensitive, specific diagnosis of malaria when performed well but also
allows quantification of malaria parasites and identification of the infecting species. This is done by examining
a stained thick and/or thin blood film for the presence of malaria parasites. Thick films are recommended for
parasite detection and quantification and can be used to monitor response to treatment, while, thin films are
recommended for species identification and can also be used for parasite quantification.
In nearly all cases of symptomatic malaria, examination of thick and thin blood films by competent
microscopes will reveal malaria parasites, but the accuracy of diagnosis is strongly dependent on the
competence of the microscopist. High-quality light microscopy requires well- trained, skilled staff, good
staining reagents, clean slides and, often, electricity to power the microscope. It also requires a continuous
quality assurance system.
The important advantages of Microscopy are:
Low direct costs, if laboratory infrastructure to maintain the service is available;
High sensitivity, if the performance of microscopy is high;
Differentiation of Plasmodia species;
Determination of parasite densities – notably identification of hyperparasitaemia;
Detection of gametocytaemia;
Allows monitoring of responses to therapy and
Can be used to diagnose many other conditions.
Although nucleic acid amplification-based tests are more sensitive, light microscopy is still considered the
“field standard” against which the sensitivity and specificity of other methods must be assessed. A skilled
microscopist can detect asexual parasites at a density of < 10 per µL of blood, but under typical field
conditions, the limit of sensitivity is approximately 100 parasites per µL.
Good performance of microscopy can be maintained through adequate training and supervision of laboratory
staff to ensure competence in malaria diagnosis, good quality slides and stains, provision and maintenance
of good microscopes and maintenance of quality assurance and control of laboratory services.
Rapid Diagnostic Tests (RDT)
Rapid diagnostic tests (RDTs) are immuno-chromatographic tests for detecting parasite-specific antigens in a
finger-prick blood sample. Malaria RDTs should be used if quality-assured malaria microscopy is not readily
available.
Some RDTs can detect only one species (P. falciparum); others allow detection of one or more of the other
species of human malaria parasites (P. vivax, P. malariae and P. ovale).
RDTs for detecting PfHRP2 can also be useful for patients who have received incomplete antimalarial
treatment, in whom blood films can be negative.
RDTs cannot be used for parasite quantification.
12
Current tests are based on the detection of histidine-rich protein 2 (HRP2), which is specific for P. falciparum,
and Plasmodium lactate dehydrogenase (pLDH) which is specific for P. vivax and other species.
The tests have many potential advantages, including:
Rapid provision of results and extension of diagnostic services to the lowest-level health facilities and
communities;
Fewer requirements for training and skilled personnel (for instance, a general health worker can be
trained in 1 day); and
Reinforcement of patient confidence in the diagnosis and in the health service in general.
Several studies have shown that health workers, volunteers and private sector providers can, with adequate
training and supervision, use RDTs correctly and provide accurate malaria diagnoses. RDTs are relatively
simple to perform and to interpret, and they do not require electricity or special equipment, but are not
sensitive in detecting low parasitaemia. Use of RDTs is not recommended for follow-up assessment after an
initial antimalarial treatment, as most tests, especially HRP2 based tests; remain positive for 1–5 weeks
following effective antimalarial treatment and clearance of parasites.
13
Uncomplicated malaria
A patient who presents with symptoms of malaria and a positive parasitological test (microscopy or RDT) but
has no signs of severity or features of severe malaria and no evidence of vital organ dysfunction is defined as
having uncomplicated malaria.
Probable (clinical) uncomplicated malaria
In malaria-endemic areas, malaria should be suspected in any patient presenting with a history of fever or
temperature ≥ 37.5 °C without any other obvious cause.
A patient who presents with symptoms of malaria, mainly fever with no any other obvious cause, without
signs of severity or evidence of vital organ dysfunction, and is treated presumptively as malaria without
parasitological confirmation by a diagnostic test (due to unavailability of diagnostic test in a very rare
situation), is defined as probable (clinical) uncomplicated malaria case.
Confirmed uncomplicated falciparum malaria
A patient who presents with symptoms of malaria and a positive parasitological test (microscopy or RDT) of
P. falciparum, but with no features and sign of severe malaria
Confirmed uncomplicated vivax malaria
A patient who presents with symptoms of malaria and a positive parasitological test (microscopy or RDT) of
P. vivax, but with no features and sign of severe malaria
Confirmed uncomplicated mixed infection
A patient who presents with symptoms of malaria and a positive parasitological test (microscopy or RDT) of
P. falciparum and P. vivax, but with no features and sign of severe malaria
Severe malaria
Severe malaria is defined as acute falciparum malaria with signs of severe illness and/or clinical or laboratory
evidence of vital organ dysfunction.
Severe falciparum malaria should be diagnosed if there are asexual forms of P. falciparum in a blood film
from a patient showing any of the following clinical features or laboratory findings (singly or in combination).
Clinical features of severe malaria:
Impaired consciousness: A Glasgow coma score < 11 in adults or a Blantyre coma score < 3 in children
(including unrousable coma);
Prostration, i.e. generalized weakness so that the patient is unable to sit, stand or walk without
assistance;
CASE DEFINITIONS
14
Multiple convulsions: more than two episodes within 24h;
Deep breathing and respiratory distress (acidotic breathing);
Acute pulmonary edema and acute respiratory distress syndrome;
Circulatory collapse or shock, systolic blood pressure < 80mm Hg in adults and < 50mm Hg in children;
Clinical jaundice plus evidence of others vital organ dysfunction; and
Abnormal spontaneous bleeding
Laboratory and other findings:
Hypoglycemia (< 2.2mmol/l or < 40mg/dl);
Metabolic acidosis (plasma bicarbonate < 15mmol/l);
Severe normocytic anemia (hemoglobin < 5g/dl, packed cell volume < 15% in children; <7g/dl, packed
cell volume < 20% in adults);
Hemoglobinuria;
Hyperlactatemia (lactate > 5mmol/l);
Renal impairment (serum creatinine > 265μmol/l); and
Pulmonary edema (radiological).
Hyperparasitaemia
Acute kidney injury (serum creatinine 265mmol/litre or greater).
Probable severe malaria
A patient with suspected malaria (fever or history of fever, with no other obvious cause) presenting with one
or more clinical features or laboratory findings of severe malaria, and requiring hospitalization that is not
confirmed parasitologically
However, this should be kept in mind that all suspected severe malaria cases must be parasitological
confirmed by microscopy and/or RDT.
Confirmed severe malaria
A patient with parasitological confirmation of P. falciparum (either by microscopy or RDT) presenting with
one or more clinical features or laboratory findings of severe malaria.
Below definition is mainly for elimination program:
Autochthonous: A case locally acquired by mosquito-borne transmission, i.e. an indigenous or introduced
case (also called ‘locally transmitted’).
Indigenous case: A case contracted locally with no evidence of importation and no direct link to transmission
from an imported case
Induced case: A case the origin of which can be traced to a blood transfusion or other form of parenteral
inoculation of the parasite but not to transmission by a natural mosquito-borne inoculation
15
Imported case: Malaria case or infection in which the infection was acquired outside the area in which it is
diagnosed
Introduced case: A case contracted locally, with strong epidemiological evidence linking it directly to a known
imported case (first-generation local transmission)
Locally acquired case: A malaria case that is acquired locally by mosquito-borne transmission
Note: Locally acquired cases can be indigenous, introduced, relapsing or recrudescent; the term
“autochthonous” is not commonly used.
17
UNCOMPLICATED MALARIA
First line drug treatment
Probable uncomplicated malaria
All suspected malaria cases should first be tested by microscopy or RDT for parasitological confirmation and
then treated properly. Where confirmation by microscopy or RDT is not available, probable uncomplicated
malaria should be treated as possible vivax malaria with Chloroquine.
Confirmed uncomplicated falciparum malaria
Treat children and adults with uncomplicated P. falciparum malaria (except pregnant women in their first
trimester) with Artemether + lumefantrine.
Standard tablets containing 20 mg artemether and 120 mg lumefantrine, 40 mg artemether and 240 mg
lumefantrine, 60 mg artemether and 260 mg lumefantrine and 80 mg artemether and 480 mg lumefantrine
and in a fixed-dose combination formulation. A total dose of 5–24 mg/kg bw of artemether and 29–144
mg/kg bw of lumefantrine. Artemether + lumefantrine is given twice a day for 3 days (total, six doses). The
first two doses should, ideally, be given 8 h apart.
An advantage of this ACT is that lumefantrine is not available as a monotherapy and has never been used
alone for the treatment of malaria.
Absorption of lumefantrine is enhanced by co-administration with fat. Patients or caregivers should be
informed that this ACT should be taken immediately after food or a fat containing drink (e.g. milk),
particularly on the second and third days of treatment.
Artemether–lumefantrine has a wide therapeutic index and is generally well tolerated, with reported side
effects such as nausea, dizziness and headache that are not easily distinguishable from symptoms of acute
malaria.
Artemether–lumefantrine should not to be administered to patients with known hypersensitivity to either
artemether or lumefantrine.
Decreased exposure to lumefantrine has been documented in young children (<3 years) as well as pregnant
women, large adults, patients taking mefloquine, rifampicin or efavirenz and in smokers. As these target
populations, may be at increased risk for treatment failure, their responses to treatment should be
monitored more closely and their full adherence ensured.
TREATMENT
18
Artemether–lumefantrine has not been studied extensively in patients > 65 years or children weighing < 5
kg. So, these patients should be monitored closely when taking this medication.
Gametocytocidal therapy in confirmed uncomplicated falciparum malaria: A single dose of Primaquine at
0.25 mg base/kg is both effective in blocking transmission and unlikely to cause serious toxicity in individuals
with any of the G6PD-deficiency variants. Therefore; single dose of 0.25 mg/kg bw Primaquine with ACT
should be given to patients with confirmed P. falciparum malaria to reduce transmission. G6PD testing is not
required. The safety of Primaquine as a P. falciparum gametocytocide is reviewed and it is concluded that a
single dose of 0.25 mg/kg bw of Primaquine base is unlikely to cause serious toxicity, even in people with
G6PD deficiency. Thus, a single dose of 0.25mg/kg bw Primaquine base should be given on the first
day of treatment, in addition to an ACT, to all patients with parasitological confirmed P. falciparum
malaria (except pregnant women, infants aged < 6 months and women breastfeeding) because there are
insufficient data on the safety of its use in these groups.
Tolerability can be improved by taking Primaquine with food.
Confirmed uncomplicated vivax malaria:
The objectives of treatment of vivax malaria are: 1) to cure the acute blood stage infection and, 2) to clear
hypnozoites from the liver to prevent future relapses which is known as “radical cure”.
Chloroquine remains an effective treatment for the blood stage of vivax malaria in Afghanistan. Oral
Chloroquine at a total dose of 25 mg base/kg bw in three days, is effective and well tolerated treatment of
P.vivax malaria, and is considered safe in pregnancy. Chloroquine is given at an initial dose of 10 mg base/kg
bw, followed by 10 mg/kg bw on the second day and 5 mg/kg bw on the third day. Lower total doses are not
recommended, as these encourage the emergence of resistance.
Anti-relapse treatment for confirmed vivax malaria:
The relapses originating from liver hypnozoites can be prevented by giving Primaquine. To achieve radical
cure and prevent relapse, treat P. vivax malaria in children and adults (except pregnant women, infants aged
< 6 months, women breastfeeding and people with known G6PD deficiency) with a 14-day course of 0.25 mg
base/kg Primaquine per day.
Primaquine causes dose-limiting abdominal discomfort when taken on an empty stomach; they should
therefore always be taken with food. Primaquine should be given only to patients with parasitological
confirmed vivax malaria. If feasible, determine the G6PD status of patient before administration of
Primaquine.
Where it is not feasible to determine the G6PD status, Primaquine should be given at a dose of 0.75mg
base/kg once a week for 8 weeks under close medical supervision to detect and manage possible cases of
haemolysis. At this dose and schedule, severe hemolysis in-patient with mild to moderate G6PD deficiency is
rare.
19
Anti-relapse treatment and G6PD status:
Patient with normal G6PD level should be treated with 0.25 mg/kg bw per day Primaquine once a day
for 14 days,
Patient with intermediate deficiency can be treated with weekly dose of Premaquine (0.75mg base/kg
once a week for eight weeks) with close clinical follow up, since severe haemolysis in-patient with
moderate G6PD deficiency is rare.
Some heterozygote females who test as normal or not deficient in qualitative G6PD tests may have
intermediate G6PD deficiency and can still haemolyse substantially. Intermediate deficiency (30–80% of
normal) and normal enzyme activity (> 80% of normal) can be differentiated only with a quantitative test.
When the quantitative testing is not available, all females should be considered as potentially having
intermediate G6PD and should be treated with weekly dose of Primaquine (0.75mg base/kg once a week
for eight weeks) with close clinical follow up.
Primaquine should not be given to patients with known severe G6PD deficiency
Confirmed uncomplicated Mix (Pf + Pv) malaria:
Treatment of confirmed uncomplicated mix malaria (P. falciparum + P. vivax) is same as treatment of
confirmed uncomplicated P. falciparum with Artemether + lumefantrine (as mentioned in section 5.1.1.2),
with adding Primaquine for anti-relapse treatment of P. vivax infection (as mentioned in section 5.1.1.3).
Second line drug treatment
Quinine should be considered as second line treatment for patients with recurrent malaria, after completing
the first line treatment, due to treatment failure.
Recurrence of malaria can result from re-infection or recrudescence (treatment failure). Treatment failure
may result from drug resistance or inadequate exposure to the drug due to sub-optimal dosing, poor
adherence, vomiting, unusual pharmacokinetics in an individual /or substandard medicines.
Before starting the second line treatment, it is important to determine:
Whether the patient vomited previous treatment or did not complete a full course of treatment
Adequate dose and course of 1st line treatment was given according to the National Guidelines
If there are other causes of febrile illness to be excluded
Parasitological confirmation of malaria (whether or not this was confirmed before the initial treatment).
The patients initially treated for falciparum malaria that return with confirmed vivax infections should be
treated with CQ as for first line treatment, and similarly, patients initially treated for vivax malaria that return
with confirmed falciparum infections should be treated with recommended ACT as for first line treatment.
These are not treatment failures and the 2nd line treatment should not be given to these groups of patients.
Treatment failure must be confirmed parasitologically. This may require referring the patient to a facility with
microscopy. In individual patients, it may not be possible to distinguish recrudescence (treatment failure)
20
from re-infection, although lack of resolution of fever and parasitaemia or their recurrence within 4 weeks
of treatment are considered failures of treatment. Patients should be asked whether they received
antimalarial treatment within the preceding 1–2 months.
Recurrence of fever and parasitaemia > 4 weeks after treatment may be due to either recrudescence or a
new infection. The distinction can be made only by PCR genotyping of parasites from the initial and the
recurrent infections. As PCR is not routinely used in patient management, all presumed treatment failures
after 4 weeks of initial treatment should, from an operational standpoint, be considered new infections and
be treated with the first-line.
Additional Considerations for Clinical Management
Give first dose under supervision and observe for half an hour. Repeat if vomits within half an hour. Patients
with repeated vomiting require admission. Check for dehydration and treat if necessary.
In young children, high fevers are often associated with vomiting, regurgitation of medication and seizures.
They are thus treated with antipyretics and, if necessary, fanning and tepid sponging. Antipyretics should
be used if the core temperature is > 38.5 ºC. Paracetamol (acetaminophen) at a dose of 15 mg/kg bw every
4 h is widely used; it is safe and well tolerated and can be given orally or as a suppository.
Give second and third dose of medicine for treatment at home. Explain how to give the treatment. Explain
to caregivers that it is important for infants to breastfeed frequently, and older children to drink plenty of
fluids, to prevent dehydration.
Explain to caregivers that if someone is abnormally sleepy or difficult to wake, or has convulsions, or has
difficulty in breathing these are danger signs of severe illness. Seek treatment immediately. Ask the patient
to return after 2 days if there is no improvement.
Some patients cannot tolerate oral treatment and will require parenteral administration for 1–2 days, until
they can swallow and retain oral medication reliably. Although such patients do not show other signs of
severity, they should receive the same initial antimalarial treatments recommended for severe malaria. The
initial parenteral treatment must always be followed by a full 3-day course of ACT.
Anti-emetics are potentially sedative and may have neuropsychiatric adverse effects, which could mask or
confound the diagnosis of severe malaria. They should therefore be used with caution.
SEVERE MALARIA
Severe malaria is a medical emergency, with a very high fatality if not managed urgently and appropriately.
The management involves the use of specific antimalarial medicines and secondly the adjuvant management
of the features of severity or accompanying complications.
21
Antimalarial drug treatment of severe malaria
Hospital level
Artesunate IV/IM: Treat adults and children with severe malaria (including infants, pregnant women in all
trimesters and lactating women) with intravenous or intramuscular (IV or IM) Artesunate for at least 24 h
and until they can tolerate oral medication. The recommended parenteral dose of Artesunate is 2.4mg/kg
body weight given intravenously or intramuscularly at admission (time = 0), then at 12h, 24h, then once a
day. Children weighing < 20 kg should receive a higher dose of Artesunate (3 mg/kg bw per dose) than larger
children and adults to ensure equivalent exposure to the drug. Artesunate is dispensed as a powder of
Artesunic acid, which is dissolved in sodium bicarbonate (5%) to form sodium Artesunate. The solution is
then diluted in approximately 5 mL of 5% dextrose and given by intravenous injection or by intramuscular
injection into the anterior thigh. The solution should be prepared freshly for each administration and should
not be stored.
Artemether IM: If parenteral Artesunate is not available, use intramuscular artemether in preference to
Quinine for treating children and adults with severe malaria. The initial dose of artemether is 3.2 mg/kg bw
intramuscularly at time of admission. The maintenance dose is 1.6 mg/kg bw intramuscularly daily.
Artemether is dispensed dissolved in oil and given by intramuscular injection into the anterior thigh.
Intramuscular artemether may be absorbed more slowly than water-soluble Artesunate, which is absorbed
rapidly and reliably after intramuscular injection.
Quinine IV: Last option is Quinine treatment for severe malaria when parenteral Artesunate and artemether
is not available. Studies of pharmacokinetics show that a loading dose of Quinine (20 mg salt/kg bw) provides
therapeutic plasma concentrations within 4h. The maintenance dose of Quinine (10mg salt/ kg bw) is
administered at 8h intervals, starting 8h after the first dose. If there is no improvement in the patient’s
condition within 48h, the dose should be reduced by one third, i.e. to 10mg salt/kg bw every 12h.
Rapid intravenous administration of Quinine is dangerous. Each dose of parenteral Quinine must be
administered as a slow, rate-controlled infusion (usually diluted in 5% dextrose and infused over 4 h). The
infusion rate should not exceed 5 mg salt/kg bw per h. Quinine must never be given by intravenous bolus
injection, as lethal hypotension may result.
Antimalarial drugs should be given parenterally for a minimum of 24h and replaced by oral medication as
soon as it can be tolerated. Anytime, after 24h parenteral treatment, the patient can start swallowing, the
parenteral treatment should be stopped and full treatment course of 3 days oral Artemether + Lumefantrine
with single dose Primaquine as gametocide, must be giver to the patient. Intramuscular injections should be
given into the anterior thigh and not the buttock. Do not attempt to give oral medication to unconscious
children.
Health center level
At health centers (BHC, CHC, mobile team, SHC) where complete treatment of severe malaria is not possible,
all severe malaria patients (adults and children) should be given the initial single intramuscular dose of
22
Artesunate (as pre-referral treatment) and then refers the patient to an appropriate facility for further care.
Where intramuscular Artesunate is not available; use artemether in preference to Quinine.
Health Post level
The Community Health Workers (CHWs) at the Health Post (HP) level, should be trained on major signs of
sever malaria and they should refer any sever malaria case to the health center/or hospital for proper
diagnosis and treatment.
MANAGEMENT OF COMPLICATIONS
Severe malaria is associated with a variety of manifestations and complications, which must be
recognized promptly and treated as shown below.
Manifestation or
complication Immediate management
Coma
(cerebral malaria)
Maintain airway, place patient on his or her side, exclude other treatable
causes of coma (e.g. hypoglycaemia, bacterial meningitis); avoid harmful
ancillary treatments, intubate if necessary.
Hyperpyrexia Administer tepid sponging, fanning, a cooling blanket and paracetamol.
Convulsions Maintain airways; treat promptly with intravenous or rectal diazepam,
lorazepam, midazolam or intramuscular paraldehyde. Check blood glucose.
Hypoglycaemia
Check blood glucose, correct hypoglycaemia and maintain with glucose-
containing infusion. Although
hypoglycaemia is defined as glucose < 2.2
mmol/L, the threshold for intervention is
< 3 mmol/L for children < 5 years and <
2.2 mmol/L for older children and adults
Severe anaemia Transfuse with screened fresh whole blood.
Acute pulmonary
edema
Prop patient up at an angle of
45o, give oxygen, give a diuretic,
Stop intravenous fluids, intubate and add positive end-expiratory pressure or
continuous positive airway pressure in life-threatening hypoxaemia.
Acute kidney injury
Exclude pre-renal causes, check fluid balance and urinary sodium; if in
established renal failure, add haemofiltration or haemodialysis, or, if
not available, peritoneal dialysis.
Spontaneous bleeding
and coagulopathy
Transfuse with screened fresh whole blood (cryoprecipitate, fresh frozen plasma
and platelets, if available); give vitamin K injection.
23
Malaria treatment in pregnancy
Treatment of probable uncomplicated malaria:
All pregnant women with probable uncomplicated malaria should be treated with CQ and referred for a
parasitological diagnosis.
Treatment of confirmed uncomplicated falciparum malaria
First trimester of pregnancy: Quinine (oral) 10 mg salt /kg (maximum 600mg) three times a day plus
Clindamycin 10mg/kg 2 times a day. All medicines should be given for seven days.
Second and third trimester: AL as above.
Treatment of confirmed uncomplicated vivax malaria
All trimesters: CQ as above.
Treatment of confirmed uncomplicated Mix malaria
Treatment of Mix (P. falciparum + P. vivax) malaria during pregnancy is same as treatment of
confirmed uncomplicated falciparum malaria in different trimesters of pregnancy.
Primaquine is contraindicated.
Treatment of probable or confirmed severe malaria
Same as treatment of severe malaria among others; see above (treatment of severe malaria).
Primaquine is contraindicated and should not be given during pregnancy or to breastfeeding
mothers.
