Invasive Meningococcal Disease


The San Francisco Department of Public Health recommends that HIV positive people, gay men, and other men or transgender people who have sex
with men get vaccinated against meningococcal disease, a rare but serious illness caused by meningococcal bacteria. The advice is consistent with the U.S. Advisory Committee on Immunization Practice's recent decision to recommend the meningococcal ACWY vaccine for HIV positive people age 2 months and older.

Zika Virus Information

Zika is an infectious disease caused by the Zika virus. It is most commonly transmitted to people by mosquito bites. Symptoms of Zika typically include fever, rash, joint pain, and/or red eyes. Zika is currently circulating in countries in Latin America and the Caribbean, as well as Puerto Rico. It is not circulating in the continental United States. In response to concerns regarding a potential role of Zika virus in causing birth defects, the Centers for Disease Control and Prevention (CDC) has issued a travel alert for people traveling to regions and certain countries where Zika virus transmission is ongoing.

Promoting Healthier International Travel


Many travelers head overseas without the protection of effective vaccines or medications to prevent common, debilitating, and life-threatening diseases such as malaria and viral hepatitis. The San Francisco Department of Public Health encourages international travelers to visit a travel medicine specialist prior to departure. 

If your health system does not offer a travel medicine specialist, the AITC Immunization & Travel Clinic is open to the public.
