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
