The Los Angeles County Department of Public Health has declared a community-wide outbreak of hepatitis A after a significant increase in cases. In 2024, 165 cases were reported, tripling the number from the previous year. So far in 2025, 29 cases have been identified, according to county health officials.
Hepatitis A, a highly contagious virus affecting the liver, is typically spread through contaminated food or water. While the disease often affects unhoused individuals, recent cases have mostly been among people without traditional risk factors, such as homelessness or drug use. The Los Angeles Times reports that the outbreak has also been detected through elevated virus levels in local wastewater.
Dr. Muntu Davis, the L.A. County health officer, emphasized the importance of vaccination, stating, “The hepatitis A vaccine is safe, effective, and offers long-term protection.” Public Health is urging residents to get vaccinated, especially those who have not previously received the vaccine. Vaccination is available through healthcare providers, pharmacies, and county public health clinics.
Symptoms of hepatitis A include fever, fatigue, stomach pain, nausea, and jaundice. Most people recover without lasting liver damage, but the disease can lead to severe complications. Seven deaths have been linked to the outbreak, according to LAist.
