  1. *These calculations carried out by NACO.
  2. †HIV prevalence from the sentinel surveillance of 2005 in Andhra Pradesh applied as follows [2,6]: median HIV prevalence of 2% from 23 antenatal sentinel surveillance clinics at medical colleges or district headquarter hospitals (sample 400 at each clinic, range of HIV prevalence 0.25–3.5%) applied to urban and rural women 15–49 years old, and 20% higher prevalence than this applied to urban and rural men; median HIV prevalence of 22.8% from 11 STI sentinel surveillance clinics mostly at medical colleges or district headquarter hospitals (sample 250 at 10 clinics and 219 at one clinic, range of HIV prevalence 4–32.4%) applied to urban and rural men assumed to get STI annually, and 83.3% of this prevalence applied to urban and rural women assumed to get STI annually; median HIV prevalence of 12.8% from seven sentinel surveillance sites for female sex workers (sample 250 each, range of HIV prevalence 5.2–26.8%); HIV prevalence of 6.45% from one sentinel surveillance site for men who have sex with men (sample 217); the total HIV prevalence of 3.35% in people 15–49 years of age calculated by dividing the total number calculated to have HIV by the total population in this age group.
  3. ‡Excludes men and women shown separately in other categories below.
  4. §In this method, 6% urban men and women and 6.3% rural men and women were assumed to get STI annually; this portion was assumed to cover high-risk groups in the population, excluding female sex workers and men who have sex with men, shown separately [3,6].
  5. ¶0.55% of urban and rural women 15–49 years of age, comprising that portion of female sex workers not expected to be covered in the STI component of the calculations [6].
  6. **Number of men who have sex with men estimated in Andhra Pradesh who were not expected to be covered in the STI component of the calculations.
