ABSTRACT
To determine the incidence and risk factors in a well characterized cohort of injecting drug users who have been monitored in Psychiatry and Behavioral Sciences Department, Bahawal Victoria Hospital, Bahawalpur. Prospective and experimental. April, 06 to April, 08 in Psychiatry and Behavioral Sciences Department, QAMC and Bahawal Victoria Hospital, Bahawalpur. The 12 month incidence of HCV infection was relatively high in IDUs aged 24 years or younger [36%] and also elevated in 26-40 years old [23%] compared with older injectors [12%]. Statistically significant [P=<0.01] differences in incidence was found in subjects who belonged to low socioeconomic group [67%] verses high socioeconomic group [19%]. Similarly higher incidence [P=<0.23] seen in heterosexuals [20%] verses homosexuals IDU's [10%]. HCV incidence was particularly higher among IDU's who had been injecting for more than 6 years [P<0.01], whereas HBV incidence was not associated with duration of drug [P<0.7]. High incidence of HCV and HBV infection is seen in IDU's. Patients with age groups < 24, lower socioeconomic status and sharing of syringes among drug users and showed statistically significant [<0.05] higher chances of HBV and HCV infection
