Prevelance of HIV/AIDS decreasing over the years

According to statistics released by the National AIDS Control Organisation (NACO), in 2004 the number of people afflicted by HIV/AIDS were 0.41 per cent of the population, in 2005 0.39 per cent, in 2006 it was 0.36, in 2007 it was 0.34 and in 2008 it was 0.29.

Of the total 2.61 million people afflicted with HIV/AIDS in 2004, 1.02 million were women, while in 2008 of the total 2.27 million, 0.90 were women. The data shows that the epidemic has been stabilised in the four high prevalence states of Maharashtra, Tamil Nadu, Karnataka and Andhra Pradesh, said K Chandramoui, Director General of NACO.

However, there are trends indicating the rising HIV epidemic in other moderate to low prevalence states. Except Andhra Pradesh with HIV prevalence of one per cent, all other states have shown less than one per cent median HIV prevalence.

Trends among Injectable Drug Users are on a decline in Manipur, Nagaland and Chennai, while they are rising in Meghalaya, Mizoram, West Bengal, Mumbai, Kerala and Delhi. Among IDUs, Maharashtra, Manipur, Tamil Nadu, Punjab, Delhi, Chandigarh, Kerala, West Bengal, Mizoram and Orissa have shown high HIV prevalence of more than five per cent.

Expanded surveillance has revealed more than five per cent HIV prevalence in states such as Karnataka, Andhra Pradesh, Manipur, Maharashtra, Delhi, Gujarat, Goa, Orissa, Tamil Nadu and West Bengal.

Among female sex workers, there is a decline in southern states, reflecting the impact of interventions, while rising trends are evident in the northeast, which suggests the dual nature of the epidemic. An overall decline in HIV prevalence among ANC clinic attendees is noted at all India levels and in high prevalence states in south and northeast.

Except Andhra Pradesh with HIV prevalence of one per cent, all other states have shown less than one per cent median HIV prevalence among ANC attendees. A rising trend is seen among ANC clinic attendees in some low and moderate prevalence states. Unprotected sex (87.1 per cent heterosexual and 1.5 per cent homosexual) is the major route of HIV transmission, followed by transmission from parent to child which is 5.4 per cent and use of infected blood and blood products which is 1.1 per cent.

While injecting drug use is the predominant route of transmission in northeastern states, it accounts for 1.7 per cent of HIV infections nationally.
