Hepatitis Surveillance Report

May 11, 2017 – New Hepatitis C Infections Nearly Tripled Over Five Years

New preliminary data released today shows that, in over just five years, the number of new hepatitis C infections reported to CDC has nearly tripled, reaching a 15-year high. The greatest increases, and the highest overall number of cases, were among young people 20-29, with injection drug use as the primary route of transmission. However, the majority (three-quarters) of the 3.5 million Americans already living with hepatitis C are baby boomers, born from 1945 to 1965, who are six times more likely to be infected with hepatitis C than those in other age groups and are at much greater risk for death from the virus.

Hepatitis C Reported Cases, 2010-2015

This line graph illustrates the rise in hepatitis C infections since 2010. New hepatitis C infections have nearly tripled from 2010-2015, from 850 new cases in 2010 to 2,436 new cases in 2015.  Because of limited testing and underreporting, the number of hepatitis C cases reported to CDC do not reflect the true scale of the epidemic. CDC estimates about 34,000 new infections actually occurred in the U.S. in 2015.

The number of new hepatitis C infections reported to CDC in 2015 was higher than it’s been in 15 years – having nearly tripled since 2010 (850 new cases were reported in 2010, and 2,436 new cases reported in 2015). Because hepatitis C often has few noticeable symptoms, the number of new cases is likely much higher than what is reported. Due to limited testing and underreporting, CDC estimates the actual number of Americans newly infected is 34,000.
