Sentinel surveillance of HIV-1 infection in Tamilnadu, India.
The objective was to determine the time trends in the prevalence of HIV infection and to evaluate appropriate preventive intervention in different population groups. Sentinel surveillance of HIV-1 infection by anonymous unlinked technique was carried out in Tamilnadu from December 1989 to March 1993. The sentinel population monitored were attendees of STD clinics, blood donors and antenatal mothers. The results of HIV seropositivity were compared for each 6-month period. During the study period there was 10-fold rise of HIV seropositivity among STD patients (1% to 10%), 2-fold rise among antenatal attendees (0.37% to 0.76%), and 3-fold rise in blood donors (0.24% to 0.72%). There was a steady increase in the incidence of HIV infection among those with high risk behaviour (STD attendees) as well as in the general population. This information is of value in planning and evaluation of preventive and control programmes in India.
