Abstract
Syphilis continues to be a major health problem in India. Data regarding sero-prevalence of syphilis is largely hospital based. Majority of community based studies have been conducted on select groups. Therefore, these studies do not reflect the true prevalence of syphilis in general population. The objective of the study was to determine the sero-prevalence of syphilis in the urban and rural communities of New Delhi, using both VDRL and TPHA for screening and FTA-ABS for confirmation and discrepant analysis. Serum specimens from 178 males and 227 females aged between 15-49 years were tested. VDRL test was put up using VDRL antigen from serologist, Kolkata. TPHA and FTA-ABS were performed using commercially available kits. 6.91% (28/405) subjects were found to be seropositive for syphilis (males 10.11%, females 4.40%). Syphilis seropositivity was found to be significantly associated with low income (p=0.02) and presence of symptoms suggestive of STIs (p=0.00) among males. Positive syphilis serology was significantly associated with trichomoniasis in females (p=0.00). Community based studies utilizing one non-treponemal test plus one treponemal test for screening purpose and an additional specific test for confirmation should be used for designing a control programme.
