LANSING, Mich. — Officials have detected another case of a viral disease that has caused periodic die-offs of Michigan deer.

The state Department of Natural Resources says a deer in Genesee County tested positive for epizootic hemorrhagic disease, or EHD. It’s spread by a biting fly.

Symptoms include loss of appetite, weakness and excessive salivation. Infected deer are often found along water bodies because EHD makes them feverish and dehydrated.

DNR wildlife pathologist Tom Cooley is asking hunters to report sightings of deer that may have the illness, which also affects elk.

Michigan has had occasional EHD outbreaks since 2006. The biggest was in 2012, when more than 12,000 deer died. There were no confirmed cases in 2014 and 2015 and only a few last year.
