Data elements or variables collected over the years in HSS will have to be included in data collection under the PPTCT programme for retaining the ability to analyze trends over years.
It may not be prudent to switch over completely to PPTCT based HIV trend analysis yet, it might be helpful to continue HSS till the PPTCT programme becomes adequately mature and starts yielding robust data.
The HSS and PPTCT programme data were obtained from the National AIDS Control Organization (NACO), Government of India, New Delhi.
The PPTCT programme, started in 2002, utilizes 4567 Integrated Counselling and Testing Centers (ICTCs) (8) largely located in public sector hospitals.
Out of the 827 PPTCT sites, 750 sites that had PPTCT programme as well as ANC HSS during 2005 to 2007 were included in the analysis from 27 States of India.
Overall, HIV prevalence in the PPTCT was similar to that of HSS (Table).
Only 134 sites had PPTCT as well ANC HSS in 2005 which increased to 317 sites in 2006 and 376 sites in 2007.
HIV prevalence in HSS and PPTCT also tends to come closer as the test acceptance increases in PPTCT.
In 2007, only about 70 per cent PPTCT centers sent complete monthly reports.
Another question is whether PPTCT programme data can predict HIV prevalence in general population.
To conclude, PPTCT programme data have potential of providing HIV prevalence trends at district and sub district level in India.
