The Michigan Department of Health and Human Services said Thursday it had ramped up nighttime aerial anti-mosquito spraying in high-risk areas of western Michigan after announcing it suspects that 28 horses and one human have contracted the disease in 11 counties in the state. Eastern equine encephalitis (EEE) is present across the eastern United States as well as parts of the Midwest, but is generally rare in humans, according to the Centers for Disease Control. As of Sept. 9, only 5 people in the United States had been diagnosed with the disease in 2020, CDC data showed.
