This study aimed to measure risk behaviours and seroprevalence of HIV and h
epatitis C virus in IDUs in Manipur, North-East India, and evaluate the imp
act of the recently established Syringe and Needle Exchange Program (SNEP).
Sampling strategy was based on social networks. Peer interviewers administ
ered the study questionnaire and collected blood for anti-HCV and anti-HIV
testing. One hundred and ninety-one IDUs (85% male) took part. Average age
at first injection was 19 years and average length of time injecting was 3.
7 years. The main drug currently injected was heroin (66%). Most (93%) rep
orted having shared injecting equipment and only 42% had used the SNEP. Thr
ee-quarters (74. 7%) were infected with HIV and almost all (98%) with HCV.
Age (p < 0.001) and length of time injecting (p < 0. 001) were significantl
y associated with being HIV-positive. Over two-thirds were sexually active,
but only 3% consistently used condoms. Almost three-quarters of IDUs in th
is study were infected with HIV, most within the first two years of injecti
ng, indicating infection continues to spread at very high rates. Unsafe sex
ual practices place partners of infected ID Us at risk of infection. The SN
EP must increase its coverage to young and new IDUs before they are exposed
to blood-borne viruses.
