HIV estimation has become a standard toolfor understanding the epidemic. Although the majority of India’s populationlives in rural areas, to date, an exploration of the urban and rural HIVepidemic has not been undertaken. The objective of this study is to develop HIVestimation based on urban and rural adult populations in selected states ofIndia to understand the difference in HIV related indices geographically. Tenstates were selected based on HIV prevalence levels-Andhra Pradesh, Tamil Nadu,Karnataka, Maharashtra, Manipur, and Nagaland, Mizoram, Punjab, Odisha andJharkhand. Spectrum, version 4.53 beta 19, was used. Data files of Indiannational estimation, 2010-11 which included population, HIV SentinelSurveillance, Integrated Bio Behavioral Assessment and program coverage data,were used and alterations made wherever necessary. The urban and rural subepidemic structures and their subpopulations were separately configured in theEstimation projection package and curve fitting done. Outputs for each statewere separately analyzed. Findings show that HIV prevalence is lower in urbanthan rural areas in Tamil Nadu and Maharashtra; in Karnataka there is nodifference in HIV prevalence in the urban and rural populations; and in theremaining seven states urban HIV prevalence is higher as compared to rural HIVprevalence. In the states of Andhra Pradesh, Tamil Nadu, Maharashtra, Odishaand Punjab, the number of people living with HIV, new HIV infections and deathsamong people living with HIV is higher in the rural than in the urbanpopulation. An early and lower peak in HIV prevalence and incidence in theurban population was seen in Andhra Pradesh, Tamil Nadu, Karnataka andNaga-land, while in Maharashtra the rural peak was earlier and higher. Mizoramshows an earlier and lower peak in the rural population while Manipur shows anearlier and higher urban peak. In Odisha, the epidemic peaked earlier and waslower in the rural than the urban population. HIV prevalence in the urbanpopulation in Punjab was still peaking while HIV incidence was earlier andlower in the rural population. In Jharkhand, both urban and rural HIVprevalence and incidence are still increasing. Our findings indicate lowerlevels of HIV prevalence and incidence in the urban population as compared tothe rural populations in Maharashtra and Tamil Nadu. In the remaining eightstates, urban prevalence and incidence are higher than their ruralcounterparts. Future estimations of the HIV epidemic in the country need toadopt a similar approach to inform the design of appropriate state-levelstrategies for HIV prevention in urban and rural areas.
