There has been a confirmed case of hepatitis A in Eaton County, the Barry-Eaton District Health Department announced Wednesday.

The health department says the individual is being treated and is not at high risk of spreading the disease.

It is the first known hepatitis A case in Eaton County this year, but it is not yet known whether the case is connected to a more widespread outbreak in southeastern Michigan, the Barry-Eaton health department said.

A Detroit Free Press analysis determined Michigan had the highest per capita rate of hepatitis A cases among U.S. states, with more than 500 Michigan cases reported in 2017. Most of those cases occurred in Detroit and Macomb County.
