Los Angeles County is experiencing a major hepatitis A outbreak, with 165 cases in 2024—triple the number in 2023 and the highest in a decade. Seven deaths are linked to the outbreak. Unlike previous outbreaks primarily affecting the homeless, this one impacts a wider population, prompting health officials to urge vaccination. The virus spreads through contaminated food, water, and contact with infected individuals. Wastewater data reveals a broader infection rate than confirmed cases. Health officials stress the importance of vaccination, especially for vulnerable populations, and improved hygiene practices.
