Hepatitis A Virus (HAV)

Santa Cruz Hepatitis A, 2017

The Public Health Division in the County of Santa Cruz has been investigating an increased number of Hepatitis A cases. Since April 2017, the County has 73 confirmed cases. They usually have 1-2 confirmed cases per year. The investigation is ongoing and challenging because of the long incubation period of the disease (15 to 50 days) and the difficulty experienced to contact many individuals sickened with the illness who are homeless and/or illicit drug users. To date, no common source of food, beverage, or other cause has been identified; as a result, the source of the outbreak remains undetermined.

HEPATITIS A CAN BE PREVENTED WITH A SAFE AND EFFECTIVE VACCINE.

Vaccination efforts are being implemented in targeted locations by County staff and in collaboration with health care partners.

Contact Public Health Department Communicable Disease Unit at (831) 454-4114. Locations of vaccination efforts will be updated shortly.

Clinicians should promptly report confirmed and suspect cases of HAV to Santa Cruz County Public Health / Communicable Disease Unit (CDU) via fax to (831) 454-5049 using the Confidential Morbidity Report (CMR).

  • Copies of pertinent laboratory testing results and clinical notes should be included.
  • Collection of contact information and travel history is of utmost importance.
