Needle Exchange

There are likely 18,000-20,000 PWID living in King County. Needle exchange is the most effective strategy available to prevent HIV in members of this population who are not in drug treatment. It also protects non-injecting family members and sex partners. Without a vaccine or a cure, prevention is the only tool we have to control the spread of HIV. Public Health provides needle exchange for four reasons:

• Needle exchange reduces blood-borne diseases in our communities without increasing drug use. Several studies have shown compelling evidence that needle exchange programs decrease HIV and hepatitis transmission, but do not increase the use of injection drugs.¹
• Preventing HIV infection in people who inject drugs also prevents HIV in women and newborn children. Many women are at risk for HIV because of their own injection drug use or because they are sexual partners of injection drug users. In the last ten years, there have been no cases of mother-to-child transmission among resident women in King County.
• By working with people who inject drugs, we can help get them into drug treatment.
• Finally, Public Health safely disposes of all contaminated syringes turned in to the exchange. This reduces the number of discarded syringes on our sidewalks and in our bus stops, yards, parks and play grounds. Our goal is to get used syringes out of circulation as quickly as possible. The longer a syringe remains in circulation, the more opportunities there are for that syringe to pass on a blood-borne disease.

YES. HIV infection among PWID has been shown to increase 6% per year on average in cities that do not have needle exchange. In contrast, HIV declined 6% per year among PWID in cities that have exchange programs.² An Australian survey found that HIV prevalence declined 19% per year in cites with needle exchange compared to an 8% increase in cities that did not have exchange programs.³ In King County, the rate of HIV infection among PWID has remained low and stable for the past sixteen years, with only 3% of the local PWID population infected.

King County's program has also been successful in getting PWID off the streets and into drug treatment. In the last two years, Public Health needle exchange program placed 739 people in drug treatment.

King County spends $1.2 million/year on the needle exchange program. In contrast, life-time medical cost to treat one person who has HIV is estimated to be $385,200.⁴ By preventing infections in just three people per year, the needle exchange program pays for itself. By preventing HIV infections in just 1% of IDUs in King County, the program saves over $70 million in HIV-related medical costs. In this light needle exchange provides both a public health and an economic benefit to the residents of Seattle and King County.

The needle exchange is funded by disease prevention funds provided by Washington State, King County and the City of Seattle. Community-based agencies that provide needle exchange in King County may also receive private donations and grants from private foundations.
