EEE can affect humans, horses and birds. About 90% of horses that test positive for the virus die, according to Michigan health officials.

In July, Florida health officials announced an uptick in sentinel chickens that tested positive for the virus. The chickens show the presence of the virus, but they don't develop the symptoms associated with them, according to the American Veterinarian.

The virus cannot be transmitted from person to person or horse to person, Michigan health officials said.

Typically, about five to 10 cases of EEE in humans are reported in the U.S. annually, according to the CDC.
