COLUMBUS (WCMH) — After a more than 800 percent increase in hepatitis A cases, the Ohio Department of Health is urging people with certain risk factors to get vaccinated.

So far, there have been 47 cases of Hepatitis A across the state, compared to 5 at this time last year.

 According to the ODH, “People at increased risk for hepatitis A include those with direct contact with individuals infected with the virus; travelers to countries where the virus is prevalent; men who have sex with men; people who use street drugs whether they are injected or not; people with blood clotting factor disorders; people with chronic liver disease; and household members and other close contacts of adopted children newly arrived from countries where hepatitis A is common.”
