Use of intravenous drugs significantly increases the risk of contracting hepatitis B, hepatitis C and HIV. Northern Kentucky has seen dramatic increases in hepatitis B and C case rates, with many cases being associated with IV drug use.

Hepatitis B

Local cases of hepatitis B doubled from 2006 to 2013, and 50% of those with hepatitis B who were contacted by the Health Department admitted to IV drug use as a risk factor for the infection.

Hepatitis C

Hepatitis C is a contagious liver disease that ranges in severity from a mild illness lasting a few weeks to a serious (acute hepatitis C) to a lifelong illness that attacks the liver (chronic hepatitis C). It is spread primarily through contact with the blood of an infected person. The Health Department can test for hepatitis C at its county health centers.
