HIV & Hep C Statistics

An overview of the state of HIV and Hepatitus C in San Francisco, California and the U.S., updated annually.

In San Francisco

People living with HIV

San Francisco has one of the largest populations of people living with HIV in the United States with an estimated 15,990 people living with HIV.

Of the total number of San Franciscans living with HIV/AIDS at the end of 2018, 9,167 were living with HIV ever classified as AIDS. AIDS is a late-stage of HIV disease defined by a low count of CD4 cells or an opportunistic infection.

In 2018, 67% of people living with HIV in San Francisco were over age 50. In 2005, only 38% of those living with HIV were over 50.

New Diagnoses

The number of new HIV infections occurring in San Francisco continues to decrease every year. There were 197 new HIV diagnoses in 2018, a 13% decrease from 2017. 

Of those newly diagnosed with HIV in 2018, 88% identified as male and 63% were men who have sex with men. Latinx people represent the highest number and proportion (38%) of people diagnosed with HIV, followed by people who are white (29%) and African American (21%). Diagnoses among African Americans and Latinx people increased slightly between 2017 and 2018. 

The percentage of people diagnosed with HIV who are experiencing homelessness is increasing. In 2018, 20% of people diagnosed with HIV (40 people) did not have housing at the time of their diagnosis (compared to 11%, 25 people, in 2016).

The majority of new HIV infections (63%) occur among men who have sex with men, followed by people who inject drugs (14%), men who have sex with men who inject drugs (10%), people who are heterosexual (5%), trans women who have sex with men (2%) and trans women who have sex with men who inject drugs (1%). (6% of people were categorized as “other/unidentified”.) 

HIV Care & Viral Suppression

91% of people newly diagnosed with HIV in 2018 entered care within one month of their diagnosis. 

About two-thirds (64%) of newly diagnosed people living with HIV are engaged in ongoing HIV care for three to nine months after their first medical visit.

Among all people living with HIV in San Francisco, 74% have their virus under control (are virally suppressed) compared to 63% in California. People who are virally suppressed have better health outcomes and do not transmit HIV to other people.

Only 33% of people who are homeless are virally suppressed. People who inject drugs also have lower rates of viral suppression (65%).

African American and Latinx people living with HIV are less likely to be virally suppressed than the population as a whole. 

Survival after AIDS diagnosis is worse for African Americans than for other racial/ethnic groups. The three-year survival probability among people diagnosed with AIDS between 2012 and 2016 was 82% for African Americans compared to 88% for whites, 94% for Latinos and 95% for Asian/Pacific Islanders.

In California

In California, 135,082 people were living with diagnosed HIV in 2017. Of those people, 73.6% were in HIV care and 63.3% achieved viral suppression.

Hispanic/Latinx people in California made up the greatest proportion of new diagnoses (47%), followed by people who are white (26%), Black/African American people (17%) and Asian people (7%). 

In the United States

In the United States, an estimated 1.1 million people were living with HIV at the end of 2016. About 15% (or about one in seven people, or 162,500 people total) don’t know they have the virus.

There were 38,739 HIV diagnoses in 2017. From 2012 – 2016, the annual number of HiV diagnoses remained stable. 

From 2012 through 2017, the annual number and the rate of new HIV diagnoses classified as stage 3 (AIDS) decreased. There were 17,604 people diagnosed with AIDS in 2017.

Hepatitis C

The End Hep C SF initiative estimates that approximately 12,000 people in San Francisco are living with active hepatitis C virus (HCV) infection, despite the existence of an easy-to-complete, highly effective cure.

People living with HIV are at higher risk for contracting HCV, and approximately 8% of PLWH are co-infected with HCV. People who inject drugs are the vast majority of those diagnosed with HCV infection, and are least likely to access treatment. Men who have sex with men (MSM) and baby boomers are also disproportionately affected by HCV. While trans women make up a small percentage of the total population of San Francisco overall (0.1%), End Hep C SF estimates that more than 1 out of every 6 trans woman is currently living with HCV.
