County Encourages Vaccinations for Hepatitis A and Mpox
November 7, 2025
Public health officials in San Diego County are urging residents to get vaccinated as cases of Hepatitis A and Mpox rise. Three Hepatitis A cases, including two hospitalizations, and 14 new Mpox infections highlight the growing concern. Vaccination remains the most effective protection for both diseases. Health officials emphasize hygiene, early vaccination, and awareness, particularly for at-risk groups such as men who have sex with men, people experiencing homelessness, and drug users. The County offers free vaccines at public health centers and clinics. Prevention through vaccination, hygiene, and early medical attention remains critical to halting further spread of both infections.
Rising Hepatitis A and Mpox cases in San Diego County have prompted renewed calls for vaccination and vigilance from local health officials. Three unrelated Hepatitis A infections and 14 new Mpox cases over the past three months underscore the persistent threat posed by both viruses, despite overall low case counts earlier in the year.
Hepatitis A, a highly contagious liver infection, spreads through contaminated food or water, or close physical contact. The disease can cause severe illness, especially among those experiencing homelessness, people who use illicit drugs, men who have sex with men, and international travelers. County Public Health Officer Dr. Sayone Thihalolipavan emphasized that the Hepatitis A vaccine provides protection even after exposure and is recommended for everyone aged 12 months and older. In addition to vaccination, good hygiene practices, including regular handwashing and safe food handling, are vital to reduce risk.
Mpox, a viral infection that spreads through close physical contact, continues to primarily affect men who have sex with men. Symptoms include painful rashes and flu-like illness that may last for several weeks. The JYNNEOS vaccine offers protection and can be administered up to 14 days after exposure. Officials urge individuals who received only one dose to complete their vaccination series for full immunity.
Both vaccines are available at no cost through County public health centers, pharmacies, and clinics. Residents are encouraged to contact their healthcare providers or call 2-1-1 for assistance in scheduling.
San Diego’s proactive stance highlights the importance of prevention through vaccination, hygiene, and awareness. As public health challenges evolve, ensuring equitable access to vaccines and reliable information remains essential to protecting communities and preventing broader outbreaks. Early action, education, and community engagement will be key to keeping these infections under control.
