San Diego Hepatitis A Outbreak, 2017
Since early 2017, the Public Health Services Division, in the County of San Diego Health and Human Services Agency, has been investigating a local Hepatitis A outbreak. The outbreak investigation is ongoing. It has been 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.
Vaccination efforts are being implemented in targeted locations by County staff and in collaboration with health care partners. Health providers are asked to inform the Epidemiology Program if they have a patient suspected to have the hepatitis A infection, before the patient leaves the emergency department or provider’s office (see contact number below).

What is Hepatitis A?
Hepatitis A is a liver infection caused by the Hepatitis A virus (HAV). HAV is highly contagious. It can cause liver disease, lasting a few weeks to a serious illness lasting months. In some cases, people can die.

How Is It Transmitted?
HAV is usually transmitted by:
- Touching objects or eating food that someone with HAV infection handled.
- Having sex with someone who has a HAV infection.
What Are the Symptoms?
HAV does not always cause symptoms. Some people get HAV and have no symptoms of the diseases. Adults are more likely to have symptoms than children.
Symptoms include fever, fatigue, nausea, loss of appetite, yellowing of the eyes (jaundice), stomach pain, vomiting, dark urine, pale stools, and diarrhea.
Hepatitis A can be prevented with a safe and effective vaccine.
|Who Is At Increased Risk for Getting HAV Infection?
Note: individuals with chronic liver disease (i.e., cirrhosis and hepatitis C) may not be at increased risk of getting HAV infections but are at increased risk of having poor outcomes if they are infected with HAV.
How Can HAV Be Prevented?
- Get two shots of the HAV vaccine. The vaccine may be given as a twin vaccine against both Hepatitis A and B.
- Don’t have sex with someone who has HAV infection.
- Use your own towels, toothbrushes, and eating utensils.
- Don’t share food, drinks, or smokes with other people.
