Age-specific frequency of screen-detected hepatitis C virus seropositivity in men from the Punjab province of Pakistan.

Pakistan is a South Asian country with a high population seroprevalence of anti-hepatitis C virus (anti-HCV) antibody. In administrative districts of its most populous province, Punjab, the frequency of seropositivity for HCV in different age groups of adult men, the usual bread winners for their families, is not known. This study describes the frequency and age-distribution of seropositivity for anti-HCV antibodies in 58,680 clinically healthy, adult men, from nine districts of the Punjab province in Pakistan, undergoing pre-employment health screening.
