ICLAC Newsletter – Mid-May 2024

Viral hepatitis can increase the risk for liver disease, cancer, and death among infected individuals. For Hepatitis A and Hepatitis B viruses, vaccination is our most effective tool in protecting patients. We are urging healthcare providers to take actions to improve routine screening and vaccinations for hepatitis.

Most viral hepatitis is caused by Hepatitis A virus (HAV), Hepatitis B virus (HBV), and Hepatitis C virus (HCV). Risk factors for viral hepatitis infection differs for each virus, but can be related to certain medical conditions, occupation-related exposure, travel to high-risk areas, sexual behaviors, and sharing drug-injection equipment.


HAV can cause a vaccine-preventable liver infection after ingestion of contaminated food or water and is more common in places with poor sanitation. Los Angeles County has recently experienced increases in HAV transmissionamong persons experiencing homelessness or using illicit drugs. The CDC recommends individuals follow their recommended vaccine schedule for HAV vaccination


HBV can cause a serious liver infection that is spread through blood, semen, or certain other body fluids – even in microscopic amounts – from an infected person. Perinatal transmission can also occur.  

The CDC has updated screening recommendations for HBV, including screening at least once in a lifetime for adults aged ≥18 years. Screening reduces the incidence of HBV,leads to better prognosis for those who test positive,  and lowers the risk of transmission. Vaccination for HBV is recommended by the CDCfor all infants, children, adolescents, and has been updated to specifically include adults ages 19-59 and adults aged ≥60 years with risk factors for HBV infection.



HCV causes a liver infection that is spread through the blood.  However, if this infection is left untreated approximately 75%-85% HCV infections lead to chronic disease. It is estimated 100,000 Los Angeles County residents are living with HCV. Screening recommendations have also been updated to include all adults aged 18-79 and treatment by primary care physicians can decrease the risk of complications.

Let’s work together to promote vaccination, testing, and screening, for hepatitis to improve the health of our community.
