To describe and compare sexual and injecting risk behaviours and sexually transmitted infections (STI), hepatitis C virus (HCV) and HIV prevalence in injecting drug users (IDU) in six districts in three states of India: Manipur, Nagaland, and Maharashtra.


The respondent-driven sample consisted of 2075 IDU. Consenting participants were administered a structured questionnaire and samples of blood and urine were collected to test for HIV and STI. Data were analysed using RDSAT.


In two districts in Manipur, 77 and 98% of IDU injected heroin, whereas the main injecting drug in Nagaland was dextropropoxyphene (99%). In Mumbai/Thane, Maharashtra, the majority of respondents reported using chlorpheniramine (87%) and heroin (99%). In all districts, almost half of IDU reported generally sharing needles and syringes; consistent condom use with non-paid female partners was also low. Approximately one-quarter of IDU in Mumbai/Thane visited a paid partner in the past year. IDU with reactive syphilis serology were higher in Nagaland (7 and 19%) than in Manipur and Maharashtra. HIV in two districts of Manipur (23%, 32%) and Mumbai/Thane (16%) was greater than Nagaland (<2%). HCV prevalence was more than 50% in Mumbai/Thane and Manipur.


Irrespective of regional differences, high-risk behaviour of needle sharing and low condom use makes IDU a critical subpopulation for HIV prevention interventions. Interventions need to address the differing drug use patterns in the regions and transmission prevention among non-paid regular and casual female partners of IDU in the northeast districts and paid female partners in Mumbai/Thane.
