  1. *These data are from the 37 antenatal clinics at medical colleges and district headquarter hospitals that started PMTCT services in 2002, and do not include PMTCT services that were started in late 2005 at 64 additional antenatal clinics in smaller locations.
  2. †These data are from the 23 medical college and district headquarter hospital antenatal clinics, one in each district, that are used by NACO for calculating HIV estimates, and do not include data from 21 antenatal clinics at smaller locations; additional data from the Hyderabad medical college antenatal clinic on a sample of 15–24 years old women only not included; these 23 clinics are a subset of the 37 clinics for which PMTCT data are shown.
  3. ‡These composite HIV prevalence are weighted by the population of 15–49 years old women in each district [14].
