Hepatitis A Outbreak Response Guide for Daycare Centers

Immediate Response & Isolation Procedures

Upon confirmation or suspected Hepatitis A case, immediately isolate the affected child or staff member in a separate area with dedicated bathroom access. Notify your local health department within 24 hours—most states classify Hepatitis A as a reportable disease under CDC surveillance guidelines. Remove the affected person from food preparation and direct care roles; Hepatitis A is transmitted fecal-orally, so hand hygiene barriers are essential. Post visible signage in bathrooms and handwashing stations reinforcing proper technique with soap and warm water for at least 20 seconds, as alcohol-based sanitizers are ineffective against Hepatitis A virus.

Staff & Parent Communication & Health Department Coordination

Inform all staff and parents of potential exposure through written notice, detailing the exposure timeline and symptoms to monitor (jaundice, fatigue, abdominal pain, dark urine). Work directly with your local health department epidemiologist, who will guide you on exclusion periods—typically 7-10 days post-symptom onset for confirmed cases. Provide the health department with attendance records, meal schedules, and staff rosters so they can identify close contacts and determine if vaccination clinics are needed for non-immune individuals. Document all communications with timestamps and retain them for your facility's records and potential regulatory review.

Environmental Decontamination & Documentation Requirements

Clean and disinfect all high-touch surfaces, bathrooms, and food service areas using EPA-approved disinfectants effective against Hepatitis A virus; bleach solutions (1:100 dilution) are standard. Review food preparation practices and product sourcing records for the 2-week period prior to symptom onset; determine if contaminated food or water was a vehicle. Maintain detailed logs of cleaning dates, times, products used, and areas treated. Document all health department communications, test results, exclusion notices, and staff training sessions on Hepatitis A transmission—these records demonstrate due diligence and are often requested during investigations by state health agencies or the FDA.
