Hepatitis C on the increase in people ages 15-34.

High risk behaviors such as IV drug use is fueling the increase while tattooing and sexual activity continue to spread the disease.

To assess the incidence of hepatitis C, the researchers reviewed Pennsylvania’s hepatitis C surveillance data from 2003 (the first full year of reportable data) to 2010. They compared age-specific rates of reported cases over time.

The number of newly confirmed or probable hepatitis C cases in people 15 to 34 years of age increased from 1384 in 2003 to 2393 in 2010 (from 43 to 72 cases per 100,000 people).
