While hepatitis C mortality has dropped across the United States, county-level variations exist, according to research published in Hepatology. One in five counties reported a rise in deaths related to hepatitis C between 2013 and 2017. Based on this research, HepVu, a project that visualizes hepatitis C data in a bid to guide public health policy, created a set of maps that depict mortality information at the county level.
“Although the national hepatitis C–related death rate has declined, what that decline looks like across counties was unknown until now,” Eric Hall, PhD, of Emory University, in Atlanta, said in a press release.
Hall and colleagues looked at nationwide hepatitis C death rates and analyzed trends from 2005 to 2013 and from 2013 to 2017 using data from the National Vital Statistics Systems for 3,115 counties in the United States. The team assessed standardized mortality rates at the county level for people below 40 years of age and those over 40.
Across the nation, the mortality rate for hepatitis C hit a high of 5.20 deaths per 100,000 persons in 2013 and dropped to a low of 4.34 per 100,000 persons in 2014.
When looking at county-level mortality rates for hepatitis C, the team found that the numbers varied, with the most deaths in northern Florida and Appalachia as well as the West and Southwest. In 80% of all counties, mortality rates dropped between 2013 and 2017; 26% of counties had a larger drop than the national average decline. Yet even as hepatitis C mortality rates fell across the country, one in five counties had an increase from 2013 to 2017. Some 30% of all counties had a mortality rate lower than the Centers for Disease Control and Prevention’s National Viral Hepatitis Progress Report 2023 goal of fewer than three deaths per 100,000 people in 2017.
When accounting for age, deaths related to hepatitis C in people under age 40 in 2017 were highest in Oklahoma, New Mexico and Appalachia, with numbers rising in the central Appalachian region. As of 2017, the West Coast and Southwest had the highest mortality rates for hepatitis C in people over age 40.
“This research aims to begin filling the gap in hepatitis C surveillance across the U.S., and to visualize the epidemic and its burden distribution across states—and now counties—better informing public health decision-making and resource allocation for monitoring, prevention, and care services,” HepVu project director Heather Bradley, PhD, of Georgia State University said in the statement.
