Recommendations for Vaccination and Other Prevention Strategies

  • Offer HAV vaccine at every opportunity to patients most at-risk for HAV vaccination or serious complications from HAV including:
    • People who use injection or non-injection drugs
    • People experiencing homelessness or unstable housing
    • People who are or were recently incarcerated
    • Men who have sex with men (MSM)
    • People with chronic liver disease (cirrhosis, hepatitis B, or hepatitis C)
    • People with HIV (New Advisory Committee on Immunization Practices' Recommendation)
  • Where to Get Vaccine: 
    • For people who are insured, click here for maps of pharmacies in Philadelphia where Hep A vaccine is currently available. 
    • For people who are uninsured, click here for a list of clinics who have Hep A vaccine.
  • Recommend HAV control and prevention measures for cases:
    • Offer HAV vaccine to susceptible, close contacts of cases (e.g., household members, sex partners, persons who shared drugs with the case). Guidance for use of post-exposure vaccine is available here.
    • Advise HAV cases to take other steps to prevent transmission, such as hand washing, avoiding food preparation for others, condom use, and hard reduction practices while contagious (1 week after jaundice onset or if no jaundice, 2 weeks after illness onset).

Diagnosis and Management

  • Acute HAV infection is confirmed during the acute or early convalescent phase of infection by the presence of anti-HAV IgM in serum. Clinicians who suspect acute HAV infection should also order liver function tests. Total antibody testing alone is not adequate for the diagnosis of acute hepatitis A infection.
  • There is no treatment other than supportive care.
  • Case Reporting: Promptly report acute HAV cases to PDPH by calling 215-685-6740 (after-hours: call 215-686-4514).
