6. BRIEF RESUME OF INTENDED WORK:
INTRODUCTION:
Leptospirosis is severe and contagious bacterial infection. It is caused by
exposure to several types of the Leptospira bacteria, which can be found in fresh
water that has been contaminated by animal urine. The alternative names of
Leptospirosis are Weil disease, Ictehemorrhagic fever, Swine herd’s disease, Rice
field fever, cane-cutter fever, Swamp fever, Mud fever, heamorrhagic jaundice,
Stuttgart disease, Canicola fever and, rat fever and farmer’s disease in india.1
Leptospirosis is essentially animal infection by Serotypes of Leptospira
(spirochetes) and transmitted to man under certain environmental conditions. At
present, 23 sero groups and 200 serovars have been recognized from various part of
the world. It has high prevalence in warm humid tropical countries. The disease
manifestations are many and varied, ranging in severity from a mild febrile illness to
severe and sometimes fatal disease.2
The some sources of human infection are rats, dogs, cats, livestock and wild
animal. Once infected, animal excrete spirochetes in the urine for an extended period
of time. Leptospire survival outside the human host is dependent on the moisture
content, temperature and pH of the soil and water into which they are shed. The
majority of the human cases worldwide result from occupational exposure to rat
contaminated water or soil. Occupational groups with a high incidence of
Leptospirosis include agriculture workers, person who live or work in rat infested
environment, individuals involved in animal and husbandry or veterinary medicine,
and laboratory workers.3
Leptospirosis is a zoonotic spirochiteal disease of global importance. The
disease continues to have a major impact on people living at urban and rural areas in
developing countries. Leptospirosis is underreported due to lack of clinical suspicion
and barriers to diagnostic capacity. General physicians often lack familiarity with
the broad clinical presentation of leptospirosis. Most commonly, human infection
with pathogenic leptospira results in asymptomatic seroconversation and less
commonly in a symptomatic illness. When symptomatic, leptospirosis most often
manifests as an undifferentiated febrile illness. In endemic areas, factors such as lack
of sanitary conditions, mud flooring, together with rainy seasons and flooding
catastrophes contribute to periodic outbreaks.4
India is a developing country, about 72-74% of the people live in rural areas.
The main source of income is agriculture; several millions of them are either
marginal farmers or work on hired labour and struggle for bare necessities of life. It
is said that nearly 11% of the total wild animal population is in India. It is usually
observed that, animals are house under the same roof as human being. Therefore all
possibilities exist for the various diseases to be transmitted by the animals to man.5
6.1 NEED FOR STUDY:
According to WHO, the incidences ranges of leptospirosis from
approximately 0.1 – 1 per 1,00,000 per year in temperate climates to 10 – 100 per
1,00,000 in the humid tropics. During out breaks and high exposure risk groups,
disease incidence may reach over 100 – 1,00,000. The case-fatality rates in different
parts of the world have been reported to range from <5% to 30%. 6
Based on National Epidemiological Surveillance of Infectious diseases
(NESID), the report on prevalence of leptospirosis showed that the estimated
sources of infection of the 93 notified cases were- Farm workers (31 cases); Leisure
activities and labour at the rivers (23 cases); contact with fresh water of other than
rivers labour(16 cases); direct and indirect contact with rodents(17 cases); unknown
(6 cases). Therefore, the sources of infection are occupational or recreational
exposure in environment contaminated with urine of carrier animals, and occupation
having a chance of direct contact with urine or blood of infected animals.7
A study was conducted on prevalence of leptospirosis in Kerala, about 37
cases were selected by using simple stratified sampling techniques. The studies
showed that people belonging to 30-45 age group were affected more(51.3%), both
males and females. There was not a single case in the 0–15 age groups, with 10.8%
belonging to 60 plus age group. As in the other studies, Male cases dominated- of
the total, 68% were male and 32% were female. This is despite the fact that more
than 50% of those affected are engaged in agriculture work, identified as the major
routes of transmission.8
A study was conducted on prevalence of leptospirosis among the Pyrexia
Unknown Origin(PUO) cases in a Tertiary care Hospital of Kashmir Valley, about
72 in-patients cases were enrolled as participants. All the samples are tested by
Lepto Dipstick. The study showed that of the 72 studied cases, 43 were male and 29
female, predominantly in the age group 21 – 40 years. Results showed that 1 of 15
urban(6.66%) and 14 of the 57 rural (24.56%) patients were positive for leptospira
antibodies respectively. About 13 of the 15 patients who tested positive (86.66%)
gave a definite history of animal contact. 9
Human leptospirosis is prevalent in many states in India, sporadically or as
outbreaks, especially during rainy seasons. It affects predominantly male adults who
work in agriculture, causing severe morbidity and mortality with serious economic
repercussions to families and to society. Yet, there is no systematic leptospirosis
prevention and control programme in the country and not included under the
national health policy. Thus, Personal protection and public health control are
relevant in this disease.10
Leptospirosis is a potentially serious but treatable disease. More than half of
the total population lives in rural areas and their lives depend mainly on agriculture.
Chances of exposure to the risk factors is high due to lack of knowledge about the
illness, poor working condition and inadequate housing. Since Leptosporosis is a
public health threat and hence, it is necessary to increase awareness and knowledge
on leptospirosis among farmers in the rural areas. So, the researcher found it
relevant to evaluate the effectiveness of video assisted teaching programme on
Leptospirosis
6.2 Review of Literature:
The review of literature is an organized critique of the important scholarity
literature that supports a study and a key step in the research process. The overall
purpose of review of literature in the research study is to present a strong knowledge
base for the conduct of the research project. The main goal of a literature review is
to develop the foundation of a sound study, but it also is used for other scholarity,
educational and clinical practice activities. 11
A study on the prevalence of Leptospirosis among the 227 risks groups was
conducted in and around Nagpur. The test group included 55 patients of pyrexia
unknown origin(PUO), 42 veterinary workers, 38 Hepatitis patients and 25 village
farmers. The control group comprised of 27 Syphilis and 40 healthy groups. Test
was done either by IgM ELISA and by Microscopic agglutination test (MAT). Out
of 160 patients of the test group 56(35.0%) were positive for Leptospiral antibodies.
Of these, the positivity was 18(32.73%) amongst Pyrexia unknown origin (PUO), 15
(35.71%) of farm workers, 15(39.47%) of hepatitis and 8(32.0%) of farmers.
Leptospirosis antibodies was not detected in any of the control groups. Out of 56
leptospira cases, 39(69.64%) has a history of animal contacts. The result shows that
PUO patients with jaundice especially in presence of the history of animal contact
should be suspected more.12
A descriptive study was conducted to assess prevalence of leptospirosis
outbreak among the 942 clinically suspected cases of leptspirosis admitted into
Lokmanaya Tilak Municipal General Hospital, Mumbai. Serum samples were tested
by Tek Dri-Dot/Leptocheck. Among 165 positive serra by these test were sent to
IRR, Mumbai for detection of leptospira IgM antibodies by ELISA (panbio). About
87 positive sera were also sent to BJ Medical College, Pune for Microscopy
Agglutination Test(MAT) for serovar identification. Seropositivity with Leptocheck
Tek Dri-Dot/Leptocheck was 34.3 %, IgM ELISA positivity was 69.1% and MAT
positivity was 29.9%. Considering at least two of the above three serological test
positive, 127 cases could be diagnosed and only 89.8% of them could be diagnosed
by ELISA and rapid test. The study therefore, concluded that alongwith rapid
serological test, IgM ELISA should be routinely done for laboratory diagnosis of
leptospirosis.13
A descriptive study on prevalence of leptospirosis in Andhra Pradesh was
done among 86 suspected cases. Of these, 49(56.97%) serum samples were found
positive for leptospirosis by DGM test and IgM antibodies. The mean age of the
positive cases were 42.7 years. All the 49 positive cases had fever (100%), Myalgia
(42.9%), stiffness of the calf muscles (55.1%) and headache (32.6%) and
conjunctival suffusion (2.04%). The studies indicated that transmission was from
contaminated stagnant water. The barefooted villagers living with livestock and
rodents were significantly associated with seropositivity.14
A descriptive study on prevalence of human leptospirosis among hospital
cases of erode, South India was performed by using isolation and serological test
such as the microscopic agglutination test(MAT) and IgM-based enzyme-linked
immunosorbent assay. Out of 29 patients, 26(89.7%) were diagnosed as having
leptospiral infection. Case fatality rate was 3.4%. The age of patients ranged
between 10-70 years and median age was 42.5 years. The study results showed that
that 93.1% of the patients were male and all patients, excepts one were agriculture
labourer. This study concluded that leptospirosis is a potential health hazard of
Agriculture Workers.15
A serological survey of Leptospira infection in Nepal by one-point
microcapsule agglutination(MCA) test was done among 200 patients(104 males and
96 females) attending out patient department. Among 200 serum samples taken-
32%(64 out of 200) of the subjects possessed antibodies to leptospira. The
Leptospira-antibody prevalence was dependent of gender and geographical
areas(P>0.05). The antibody prevalence in different age and ethnic groups ranged
from 27.5 – 34.0% and 28.5 – 40.0% respectively. The difference was not
significant (P>0.05%). The reports of the results suggested that Leptospira infections
are uniformly distributed in different age, sex, ethnics and geographical areas. 16
A study to investigate the risk factors for mortality in patients with
Leptispirosis during an epidemic outbreak in northern Kerala was done through
clinical examination, laboratory investigation and leptospira serology -Microscopic
agglutination test(MAT). Of the 468 cases suspected to have leptospirosis, serology
could be done in 360 patients. Of these, MAT was positive in 282 patients. Case
fatality rate was 6.03%.Out of 282 seropositive cases 58.9 % were men and 29%
were engaged in agriculture occupations. The result shows that majority of the
patient (62.9%) had either fissures or other wounds on the feet and no patient had
direct occupational exposure to animal.17
A leptospirosis clinical-epidemiology study was made in humans and
reservoirs. Interviews and serological analyses were made on 400 persons from an
open population; 439 probable cases of leptospirosis and 1060 animal
reservoirs(cows, pigs, dogs, rats and opossums). IgM Leptospira Dipstick and
Microscopic agglutination Test(MAT) was used to detect human antibodies to
leptospiras and serovars respectively. Leptospirosis in humans was 2.2/1,00,000
inhab. In 1998, 0.7/1,00,000 in 1999 and 0.9/1,00,000 in 2000. Overall
seroprevalence was 14.2%, relatively unchanged from seroprevalences observed 20
years ago highest seroposivity was found in people over 56 years of age,
predominating males over females.Leptospirosis cases were more frequent in rural
areas. Contacts with rodents and natural water sources were significant factors
(p<0.05). Human cases (74%) occurred during the rainy season. The study
concluded that leptospirosis is still a serious illness with important clinical and
epidemiological implications. 18
A clinical study of human leptospirosis was conducted for a period of three
years in the city of Chennai, Tamil Nadu. Test was done by Dark Field Microscopy
Test. The study results showed that out of 165 samples tested for
thrombocytopaenia, 37% of the cases are found to have fall in platelet count.
Administering high doses of Penicillin can improve the Platelet count within 10
days. The study concluded that though leptospirosis is a common bacterial disease
with a well-known treatment regimen, improper diagnosis can result in death. 19
A literature review addressed to the issues on epidemiology, diagnosis and
clinical management of leptospirosis which confront public health responses, and
highlights the progress made towards understanding the leptospira genome, biology
and pathogenesis. The recent finding showed that Leptospirosis has spread from its
traditional rural base to become the cause of epidemics in poor urban slum
communities in developing countries. The overall disease burden is underestimated,
since leptospirosis is a significant cause of undifferentiated fever and frequently not
recognised. Barriers to addressing this problem have been the lack of an adequate
diagnostic test and effective control measures. China and Brazil countries have
completed the sequence of the leptospira genome. Together with new genetics tools
and proteomics, new insights have been made into the biology of leptospira and the
mechanisms used to adapt to host and external environments. Surface protein
exposed proteins and putative virulence determinants have been identified which
may serve as sub-unit vaccine candidates. Future challenges will be to translate
these advances into public health measure for developing countries. 20
