Abstract
We aim to describe trends in antenatal HIV prevalence in India, at a national and regional level from consistent sentinel surveillance sites (2003-2015) among Antenatal Clinic (ANC) attendees. Data were analyzed from a total of 1,885,207 ANC attendees recruited at ANC sites. The consistent sites were grouped by years of initiation (Group 1: 2003-2005 and Group 2: 2006-2008) and according to six regions. Chi-square test for linear trend was applied to test the statistical significance of the trend. Nationally, at Group 1 sites, HIV prevalence was 0.93% in 2003, which declined to 0.36% in 2015 (P < 0.001). Similarly, at Group 2 sites, prevalence ranged from 0.25% to 0.23% during 2006-2015 (P > 0.05). The findings suggest that HIV is conclusively declining at old sites, nationally as well as in most of the other regions but increasing in the northern region. At newer sites, the conclusive declining trend is evident only in the southern region. National AIDS response must consider these variations to allow locally appropriate responses to the epidemic.
