SESSION OBJECTIVES• List communicable diseases for which

infection control measures are indicated

• Identify modes of transmission for communicable diseases

• Identify appropriate infection control measures for common and/or serious contagious diseases

• Know the campus and community resources involved with implementing infection control measures 3

LA2/23/12•History:– Sore throat & cough x 1 day– PMH pneumonia one year ago

•Physical exam– BP 138/85 HR 115 T 98.5– Pharynx red, TM normal– Lungs clear

•Symptomatic treatment advised

LA, continuedReturns 2/28/12•CXR (obtained 2/23) was negative•Symptoms have continued, cough worse•Physical exam– BP 147/91 HR 113 T 99.0– Pharynx red, cervical adenopathy– Lungs clear, but frequent dry coughing fits,

speaking in full sentences

•Symptomatic measures continued

LA, continued2/29/12•Goes to ER - cough incessant, uncontrolled by codeine

•What is the differential diagnosis?

•What else do you need to know?

•What do you need to do?

WHAT DO STUDENTS NEED TO KNOW?**Also parents, staff, media

• Who is at risk for exposure?

• What should students do if they were exposed?

• What should students do if they have symptoms?

9

WHAT DO ADMINISTRATORS NEED TO KNOW?

• Same as students

PLUS• Extent of outbreak• Measures needed to control outbreak• Need to provide support to affected students• Need for resources• Talking points

10

WHAT DO CLINICAL STAFF NEED TO KNOW?

• Same as students and administrators

PLUS• On-site infection control measures• Clinical presentation• Diagnostic tests• Management• Reporting

11

CAMPUS INFECTION CONTROL ISSUES

• How do basic infection control principles apply in a campus environment?– Populations– Facilities– Significant functions

• What resources are needed?

• What resources are available?

TYPES OF INFECTIOUS DISEASES

ViralBacterialFungalParasiticNematodes and helminthsCritters

17

TRANSMISSION BASICS

• Airborne• Droplet• Contact• Ingestion• Blood and body fluid

18

AIRBORNE TRANSMISSION

• Airborne droplet nuclei – Small particles <5 μm of evaporated droplet

• Widely dispersed• Remain suspended in air for long periods• Indication for N95 respirator

19

TB Online

DROPLET TRANSMISSION

• Droplets generated primarily by coughing, sneezing, talking

• Droplets relatively large– Propelled short distance (< 3 feet)– Deposited on conjunctiva, nasal mucosa, mouth– Do not remain suspended in air

• Indication for surgical masking

CONTACT TRANSMISSION

• Direct contact with infected area• Fomites• Most common route of health care-associated

infections

CONTROL AND PREVENTION• Pre-exposure immunization

(for vaccine-preventable diseases)• Screening • Hand hygiene• Food and water safety• Universal precautions• Isolation and quarantine• Post-exposure immunization • Post-exposure chemoprophylaxis 27

RECOGNIZING AND MANAGING OUTBREAKS

• Disease surveillance• Contact identification and tracing• Pre- and post-exposure prophylaxis• Notification• Public health emergencies

28

INFECTION CONTROL ISSUES

• Transmission characteristics• Diagnosis• Treatment• Evaluation of the exposed individual• Control measures• Isolation/exclusion – who, what, how long• Post-exposure measures• Environmental measures

29

PERTUSSIS

ManifestationsCatarrhal stageCoughParoxysmal stage

Transmission Droplet

Incubation period Typically 7 – 10 days (range 6 -21 days)

Diagnostic testsCulturePCRDFA

Treatment Macrolide antibiotic (azithromycin)

Infectivity From onset of symptoms* to 2 weeks after onset of paroxysms

30

{Total duration 6 – 10 weeks}

PERTUSSIS, continued

Control measures

Isolate student until first five days antibiotics completed or until 21 days after onset of symptomsIsolate symptomatic contacts

Candidates for post-exposure measures

Prophylaxis indicated for household and other close contactsMonitor for 21 days after last contact

Post-exposure measures

Macrolide antibiotic (azithromycin)Update Tdap when indicated, but not effective as post-exposure measure

Cleaning and disinfecting Routine cleaning only

31

MEASLES

Manifestations

Fever, followed by cough, coryza, conjunctivitis and Koplik spotsErythematous maculopapular rash, starts on head and spreads downward

Transmission Airborne spread, as well as direct contact with infectious droplets

Incubation period 8 to 12 days

Diagnostic tests Culture, serology, RT-PCR

Treatment No specific antiviral therapy

InfectivityHighly infectiousContagious from four days before onset of rash to four days after rash appears

32

MEASLES, continued

Control measures

Isolate for 4 days after onset of rash (airborne precautions)Isolate symptomatic contactsConsider excluding asymptomatic contacts who cannot demonstrate immunity

Candidates for post-exposure measures

Anyone who cannot demonstrate immunity

Post-exposure measures

Post-exposure immunization may be effective if given within 72 hours of exposure

Cleaning and disinfecting Routine cleaning only

33

MRSA

Manifestations Pustule or boil, commonly at site of visible skin trauma

Transmission Contact

Diagnostic tests Culture and sensitivity

Treatment

Incision and drainage Empiric antibiotics may be warrantedWhen possible, obtain specimens for C&S to guide continued antibiotic choice

34

MRSA, continued

Control measures

Cover infectionsExclude athletes if wounds cannot be properly coveredHand hygieneClean shared equipmentDo not share personal items

Post-exposure measures No specific measures

Cleaning and disinfecting

Usually routine cleaning sufficientFocus on surfaces that might come in contact with uncovered infectionsClean shared equipmentRoutine laundry procedures

35

NOROVIRUS

Manifestations Diarrhea and vomitingSymptoms last 1 – 14 days

TransmissionIngestion Person-to-person (fecal-oral)Contaminated food or water

Incubation period 12 to 72 hours

Diagnostic tests PCR assays not commercially available

Treatment Symptomatic – antiemetics, rehydration

Infectivity Most contagious during symptoms and first 3 days of recovery

36

NOROVIRUS, continued

Control measures

Standard measures for control of diarrheaScrupulous hand hygieneExclude infected individuals from food preparation, health care, child careConsider isolation for 48 hours

Candidates for post-exposure measures

Reinforce hand hygiene to anyone with potential exposure

Post-exposure measures No specific measures available

Cleaning and disinfecting

Disinfect contaminated surfaces with bleach solution or other disinfectantWash contaminated clothes and linens
