An integrated counseling and testing centre is a place where a person is counseled and tested for HIV, on his own free will or as advised by a medical provider. The main functions of an ICTC include: Early detection of HIV, Provision of basic information on modes of transmission and prevention of HIV/AIDS for promoting behavioral change, reducing vulnerability and link people with other HIV prevention, care & treatment services. ICTC data can guide in identifying the various risk groups for priority targeted interventions to reduce HIV transmission in the community. To estimate the prevalence, mode of transmission, risk behavior and socio-demographic characteristics of attendees who tested HIV positive at ICTC in IGMC, Shimla for the year 2016 and prevalence of TB-HIV co-infection among HIV positive cases. This study is based on the Record review of attendees at ICTC in Indira Gandhi Medical College & Hospital in Shimla from 1st January to 31st December 2016. Data was entered using Microsoft excel software and analyzed with the help of epi info v7. This study depicts the role of ICTC & its Implementation in a Medical College. Among the 9156 total attendees in a year 2016 at ICTC, 63 were HIV Positive, so the overall prevalence of HIV among attendees was 0.69%, in which 41 were males and maximum (29) were in the age group of 35-49 years. TB-HIV co-infection was present in 3 patients out of 41 who were referred to RNTCP centre. Most common (71.42%) mode of transmission was heterosexual. Govt/ Pvt services & truck driving were the common occupations among HIV Positive Patients. Present study shows that males, 35-49 years of age group, hetero-sexual mode of Transmission & Inservice (Govt/Pvt) and truck drivers by occupation were predominate among HIV Positives. So we need to focus on these groups by IEC or BCC activities to modify the risk behavior to reverse the HIV epidemic.
