A 2006 study published in the British medical journal "The Lancet" reported an approximately 30% decline in HIV infections from 2000 to 2004 among women aged 15 to 24 attending prenatal clinics in selected southern states of India, where the epidemic is thought to be concentrated. Recent studies suggest that many married women in India, despite practicing monogamy and having no risk behaviours, acquire HIV from their husbands and HIV testing of married males can be an effective HIV prevention strategy for the general population.
