There could be three million HIV positive injection drug users (IDUs) in the world, according to an article released on September 24, 2008 in The Lancet.
To investigate the current state of HIV status in IDUs, Dr Bradley Mathers, National Drug and Alcohol Research Centre, University of New South Wales, Sydney, Australia, and colleagues from the 2007 Reference Group to the UN on HIV and Injecting Drug Use performed a systematic review of data from 148 different countries.
In the analysis, the authors estimated that 15.9 million people worldwide inject drugs. In 1998, one study reported injecting drug use in 129 countries, and of these, 103 reported HIV status. Later research indicates that at least 148 countries have IDUs, with 120 reporting HIV positive IDUs. Over 40% of IDUs are HIV positive in at least nine countries, including Estonia, Ukraine, Burma, Indonesia, Thailand, Nepal, Argentina, Brazil, and Kenya. In an examination of people between 15 and 64 years old, the analysis showed significant differences between different countries. Within this age group, the following notable proportions of IDUs and HIV status have been estimated:
- Italy and Switzerland showed the highest estimated proportions of IDUs in Western Europe, with 0.83% and 0.65% respectively.
- Spain and Portugal showed the highest proportion of IDUs who are HIV positive in Western Europe, with 39.7% and 15.6% respectively.
- The United States has an estimated rate of 0.96% IDUs, with 15.6% of these HIV positive.
The authors conclude, emphasizing the need for research in this area: "Injecting drug use occurs in most countries and HIV infection is prevalent among many populations of IDUs, representing a major challenge to global public health. People who inject drugs have the right to enjoy the highest standard of health attainable. There is a clear mandate to invest in HIV prevention activities such as needle and syringe programmes and opioid substitution treatments and to provide treatment and care for those living with HIV/AIDS. The magnitude of this risk has not be met with an equally concerted investment in research to accurately quantify the problem."
Dr. Kamyar Arasteh and Dr. Don C. Des Jarlais, Beth Israel Medical Center, Baron Edmond de Rothschild Chemical Dependency Institute, New York, contributed an accompanying comment in which they explore many risk factors taht could be contributing to injecting drug use. They say: "The one optimistic aspect of this rather gloomy situation is that, if HIV-prevention efforts are implemented on a large scale when prevalence is low in injecting drug users, it is possible to avert HIV epidemics in users. Thus it should be an imperative - for both resource constrained countries and international donors - to implement large-scale evidence-based programmes for HIV-prevention whenever there is an indication of a developing injecting drug-use problem."
