HIV-2 strikes injecting drug users (IDUs) in India

Area of Science:

• Medical Virology
• Epidemiology
• Public Health

Background:

• Manipur, India, reported the introduction of HIV-1 among injecting drug users (IDUs) in 1989, leading to rapid dissemination.
• HIV-2 was previously undetected among IDUs in Manipur, despite its presence elsewhere in India since 1991.

Purpose of the Study:

• To report the initial detection of Human Immunodeficiency Virus type 2 (HIV-2) in young injecting drug users (IDUs) in Manipur.
• To document coinfection patterns of HIV-1 and HIV-2 in this population.

Main Methods:

• Surveillance of injecting drug users in Manipur.
• Diagnostic testing for HIV-1 and HIV-2 antibodies and/or antigens.
• Analysis of coinfection status.

Main Results:

• HIV-2 infection was identified for the first time among young IDUs in Manipur.
• All individuals diagnosed with HIV-2 were also infected with HIV-1.
• The study establishes the presence of HIV-2 in the IDU population in this region.

Conclusions:

• The introduction of HIV-2 into the IDU population in Manipur is confirmed.
• The potential for rapid spread of HIV-2 within this vulnerable group warrants monitoring.
• Further observation of disease progression in coinfected individuals is crucial.
