West Nile cases continue to climb across Michigan

GRAND RAPIDS, Mich. (WOOD) — Cases of West Nile virus continue to climb in Michigan. The latest data from the Michigan Department of Health & Human Services shows more positive cases in both humans and wild animals.

Cases in humans have already been confirmed in Berrien, Delta, Genesee, Livingston and Macomb counties. A second has now been confirmed in Macomb County and Wayne County now has its first case.

There are now 39 total cases in animals, up from 26 just two weeks ago .

MDHHS data also shows the number of positive mosquito-testing pools is showing more signs of activity. The number has risen from 102 to weeks ago to 140 as of Friday.

Bay County has the most positive pools — 77. Kent County has 26 and Ottawa County has two.

According to the Kent County Health Department , approximately 80% of people infected with West Nile virus will not notice any symptoms, but they typically include body aches, joint pain and fatigue. Most WNV patients recover completely, but about 1 in 150 develop a severe illness that impacts the central nervous system. Recovery can take months, but sometimes the damage is permanent and can even be deadly.

Last year, 24 Michigan residents tested positive for West Nile virus. Since there is no vaccine or cure for WNV, the KCHD says preventative measures are the best way to stay safe.

The department recommends wearing a mosquito repellent that contains at least 10% DEET, wearing light-colored clothing and staying indoors around dusk to avoid mosquitoes’ most active time of day. The department also recommends making sure all window screens are properly sealed and removing or refreshing any standing water on your property that can serve as a breeding ground for mosquitoes.
