Sharing syringes and other equipment for drug injection is a well known route of
HIV transmission, yet injection drug use contributes to the epidemicí s spread far
beyond the circle of those who inject. People who have sex with an injection drug
user (IDU) also are at risk for infection through the sexual transmission of HIV.
Children born to mothers who contracted HIV through sharing needles or having
sex with an IDU may become infected as well.
Since the epidemic began, injection
drug use has directly and indirectly
accounted for more than one-third
(36%) of AIDS cases in the United
States. This disturbing trend appears
to be continuing. Of the 46,400 new
cases of AIDS reported in 1999,
13,833 (30%) were
Racial and ethnic minority populations
in the United States are most
heavily affected by IDU-associated
AIDS. In 1999, IDUs accounted for 33% of all AIDS cases among African
American and 35% among Hispanic adults and adolescents, compared with 23%
of all cases among white adults/adolescents.
IDU-associated AIDS accounts for a larger proportion of cases among women
than among men. Since the epidemic began, 58% of all AIDS cases among women
have been attributed to injection drug use or sex with partners who inject drugs,
compared with 31% of cases among men.
Noninjection drugs (such as "crack" cocaine) also contribute to the spread of the
epidemic when users trade sex for drugs or money, or when they engage in risky
sexual behaviors that they might not engage in when sober. One CDC study of
more than 2,000 young adults in three inner-city neighborhoods found that crack
smokers were three times more likely to be infected with HIV than non-smokers.
Strategies for IDUs Must Be Comprehensive
Comprehensive HIV prevention interventions for substance abusers
must provide education on how to prevent transmission through sex.
Numerous studies have documented that drug users are at risk for HIV through
both drug-related and sexual behaviors, which places their partners at risk as well.
Comprehensive programs must provide the information, skills, and support necessary to reduce both risks.
Researchers have found that many interventions aimed at reducing sexual risk behaviors
among drug users have significantly increased the practice of safer sex (e.g., using condoms, avoiding
unprotected sex) among participants.
Drug abuse treatment is HIV prevention, but drug treatment slots are scarce.
In the United States, drug use and dependence are widespread in the general population. Experts generally
agree that there are about 1 million active IDUs in this country, as well as many others who use noninjection
drugs or abuse alcohol. Clearly, the need for substance abuse treatment vastly exceeds our capacity to provide
it. Effective substance abuse treatment that helps people stop using drugs not only eliminates the risk of HIV
transmission from sharing contaminated syringes, but, for many, reduces the risk of engaging in risky behaviors
that might result in sexual transmission.
For injection drug users who cannot or will not stop injecting drugs, using sterile
needles and syringes only once remains the safest, most effective approach for limiting
To minimize the risk of HIV transmission, IDUs must have access to interventions that can help them protect
their health. They must be advised to always use sterile injection equipment; warned never to reuse needles,
syringes, and other injection equipment; and told that using syringes that have been cleaned with bleach or other
disinfectants is not as safe as using new, sterile syringes.
Having access to sterile injection equipment is important, but it is not enough.
Preventing the spread of HIV through injection drug use requires a comprehensive approach that incorporates
several basic principles:
- ensure coordination and collaboration among all providers of services to IDUs, their sex partners,
and their children,
- ensure coverage, access to, and quality of interventions,
- recognize and overcome stigma associated with injection drug use, and
- tailor services and programs to the diverse populations and characteristics of IDUs.
Strategies for prevention should include:
- preventing initiation of drug injection,
- using community outreach programs to reach drug users on the streets,
- improving access to high quality substance abuse treatment programs,
- instituting HIV prevention programs in jails and prisons,
- providing health care for HIV-infected IDUs, and
- making HIV risk-reduction counseling and testing available for IDUs and their sex partners.
Better integration of all prevention and treatment services is critically needed.
HIV prevention and treatment, substance abuse prevention, and sexually transmitted disease treatment
and prevention services must be better integrated to take advantage of the multiple opportunities for
intervention--first, to help the uninfected stay that way; second, to help infected people stay healthy; and
third, to help infected individuals initiate and sustain behaviors that will keep themselves safe and
prevent transmission to others.
