The survey, being carried out by the National AIDS Control Organisation (NACO) and the health ministry, spotted the change in the pattern of spread last year. It takes a district-by-district approach to covering the country and is part of the National AIDS Control Programme-III (2006-11). A report is scheduled for release in June.
What is causing concern is that pockets in states such as Delhi, Punjab, Orissa, West Bengal, Gujarat, Chhattisgarh, Madhya Pradesh and Bihar, where IDU- and MSM-related cases were never a cause for concern, now call for urgent intervention. "IDU-related HIV cases were largely found in the Northeast, so we had a system in place to address that specifically. Earlier, the focus was on the migrant population, but now we cannot restrict ourselves to just that: everywhere we look, we are finding more and more cases related to IDU and MSM," says Dr Ajay Khera, assistant director-general, NACO.
|Bihar||IDU, MSM, migrants|
|Gujarat||IDU, MSM, migrants|
|West Bengal||Migrants, eunuchs, MSM|
|Madhya Pradesh||MSM, Migrants|
IDU: Injectible drug users
***The report underlines the magnitude of the problem: "Urban centres...such as Delhi, Pune, Bangalore, Surat, Rajkot and Calcutta recorded very high HIV prevalence among MSM. Overall, 21 districts have shown greater than five per cent HIV prevalence. This suggests there may be many pockets of high prevalence among MSM, which need to be detected."
Another change in pattern revealed by the survey is that IDU-related cases are on the decline in states like Manipur and Nagaland, where it was endemic, but on the rise in West Bengal, Mumbai and Delhi. "The dip in numbers reflects our intervention policies in those northeastern states. This year, the nationwide focus has to be on IDU- and MSM-related cases," says Mayank Agarwal, joint director, NACO.
Tamil Nadu, long thought of as a poor performer in HIV prevention, now has fewer cases. "Our efforts have been on in this state for the past 15 years, and the change indicates the intervention carried out," says Khera. The other finding that has come to light in the survey is that, in the Northeast, the sex trade is the new driver of the HIV epidemic, replacing the users of injectible drugs.
The gender difference in the spread of the HIV virus brought out by the survey is that most of the HIV-positive women, who form 40 per cent of the total HIV cases, are innocent housewives or in monogamous relationships. "This too needs to be addressed urgently. HIV is a typically concentrated epidemic and the idea is to keep it in check at 0.3 per cent of the adult population in the country. The overall goal of the NACP-III is to halt and reverse the epidemic in India over the next five years through integrated programmes," says Khera.
