Los Angeles County tripled the hepatitis A infection in 2024 compared to the previous year, urging public health officials to declare a community-wide outbreak.
There were 165 confirmed cases of hepatitis A in 2024 in LA County, and the LA County Public Health Department was confirmed, adding that the wastewater has increased virus levels.
Hepatitis A is a liver infection that involves symptoms such as fever, fatigue, nausea, and yellowing. A highly contagious virus can spread from small amounts of stool contaminated objects, foods and drinks from infected people.
Inappropriate people are at a higher risk of hepatitis A due to limited access to the hand washing and toilet, but over 15% of confirmed infections in 2024 were experienced by people without housing risk factors.
Public health officials have encouraged vaccinations and good hygiene to prevent virus infection, such as washing hands with soap and water, although the risk to the general public is low.
“The continued increase in hepatitis A shows that prompt action is needed to protect public health,” said Dr. Muntu Davis, Los Angeles County Health Officer. “The hepatitis A vaccine is safe, effective and provides long-term protection.”
