I. EXECUTIVE SUMMARY
This report provides estimates of the prevalence of HTV
infection by race and ethnicity in the City and County of San
Francisco in 1993. These data are based upon the large body of
research that has been conducted in San Francisco during the past
decade, and include estimates of the number of persons at risk,
the prevalence of HTV, and the number of persons infected with
HIV.
It is estimated that approximately 28,000 men, women and
children are currently living with HIV infection in 1993,
representing almost 4% of the City's population. San Francisco
has the highest number of HIV-infected persons per capita of any
major city within the United States.
It is estimated that the majority of persons currently living
with HTV infection in San Francisco are white (61%), most of whom
are gay and bisexual men. Persons of color represent 39% of
2d with HTV. In 1992, only 25% of persons

I. EXECUTIVE SUMMARY
This report provides estimates of the prevalence of HTV
infection by race and ethnicity in the City and County of San
Francisco in 1993. These data are based upon the large body of
research that has been conducted in San Francisco during the past
decade, and include estimates of the number of persons at risk,
the prevalence of HTV, and the number of persons infected with
HTV.
It is estimated that approximately 28,000 men, women and
children are currently living with HIV infection in 1993,
representing almost 4% of the City's population. San Francisco
has the highest number of HIV-infected persons per capita of any
major city within the United States.
It is estimated that the majority of persons currently living
with HIV infection in San Francisco are white (61%), most of whom
are gay and bisexual men. Persons of color represent 39% of
those currently infected with HTV. In 1992, only 25% of persons
diagnosed with AIDS were persons of color. Together, these
findings suggest a shift in recent years towards increasing
numbers of infections among persons of color.
It is estimated that the vast majority of persons infected
with HTV in San Francisco are either gay and bisexual men,
injection drug users, or sexual partners of gay and bisexual men
or injection drug users. Although the majority of gay and
bisexual men currently living with HTV infection are white, most
injection drug users or infants and children living with HTV are
persons of color.
The following points highlight the key findings from this
report:
1. An estimated 28,000 men, women, and children are living
with HTV infection in San Francisco in 1993, representing nearly
4% of the City's population.
2. Of the 28,000 persons estimated to be living with HTV,
approximately 25,000 are gay and bisexual men, 1,700 are
injection drug users (other than gay and bisexual males), 880 are
women and heterosexual men with other risks, and 83 are infants
or children.
3. More than 10,700 persons of color are currently living
with HTV infection in San Francisco, representing 39% of all
those currently infected with HTV.
4. Among those living with HTV infection, 61% are white, 16%
are African American, 14% are Latino, 8% Asian/Pacific Islander,
and 1% are Native American.
.
II. METHODS
Estimates of the number of persons infected with HIV are
derived from estimates of the prevalence of HIV infection and the
size of the populations at risk. These estimates are based upon
numerous studies conducted in San Francisco in recent years,
including probability samples of San Francisco neighborhoods,
cohort studies of gay and bisexual men, random digit-dial
telephone surveys, clinic—based unlinked serosurveys, studies of
young men who have sex with men, surveys of childbearing women,
studies of heterosexual partners, street-based studies of
injection and non—injection drug users, and screening of blood
donors
The estimated numbers of gay and bisexual men by
race/ethnicity was based on a composite of distributions from the
following sources: reported cases of persons diagnosed with AIDS
in 1992, a random digit-dial survey of gay and bisexual men
(Communications Technologies, 1990), a survey of young men who
have sex with men conducted in 1992 and 1993 (Young Men's Survey,
1992/93), an unlinked HIV seroprevalence survey at a sexually
transmitted disease clinic (City Clinic, 1991), and data from the
1990 U.S. census.
The estimated numbers of injection drug users by
race/ethnicity was based on a composite of distributions from the
following sources: population-based household surveys of African
Americans (Polaris Research & Development, 1989), Latinos
(Fairbank, Bregman and Maullin, 1989), Filipinos (The Asian
American Health Forum/Filipino Task Force on AIDS, 1990), Chinese
(Asian American Recovery Services, 1990), Japanese (Asian
American Recovery Services, 1990), and Southeast Asians (Center
for Southeast Asian Refugee Resettlement, 1991). Other sources
of data included unduplicated counts of clients in treatment
(Community Substance Abuse Services, SFDPH, 1990-91), reported
cases of persons diagnosed with AIDS in 1992, unlinked HIV
seroprevalence surveys at several drug treatment centers,
street-based surveys of drug users (Urban Health Study, 1991-92)
and data from the 1990 census.
Estimates of the total number of adults and adolescents and
infants and children are based on the 1990 U.S. census. The
population estimates for women and heterosexual men with other
risk factors are calculated by subtracting the population size
estimates for other categories (gay and bisexual men, LDUs, and
infants and children) from the total San Francisco population
estimates by race and ethnicity.
