Seroprevalence of HIV in Manipal.

A total of 32,406 persons were screened for HIV 1 and 2 antibodies between 1991 to 1999 by Enzyme Linked Immuno Sorbent Assay at Dept. of Microbiology, KMC, Manipal which is a rural teaching hospital. There was steady increase in seropositivity from 0.38% (1991) to 9.31% (1995) and thereafter there is decrease in the seropositivity rate to 4.15% (1999); but the number of cases screened increased from 1995 onwards. The HIV seropositivity is more in males 7.49% than in females (2.52%). The male to female positivity ratio is 2.72:1, inspite of the total number of samples screened of either sexes being equal. The prevalence of HIV among STD Clinic attendants was 8.22%. The foci of infection can be traced to cities such as Mumbai and the main mode of transmission is through unprotected heterosexual contact. The decrease in the seropositivity rate from 1996 onwards could be due to the AIDS awareness among public due to the control programmes. More awareness and public education is needed towards healthy sexual practices to avoid fresh HIV cases.
