Michigan health officials have confirmed the first human case of West Nile virus (WNV) in the state this year. The person who tested positive is from Livingston County. No other details about the case have been shared.
This news is important because it means the virus is actively spreading through mosquitoes in our state. Health experts are reminding everyone to take extra care, especially during August and September, when the risk is highest.
What Is West Nile Virus?
West Nile virus is a disease spread through mosquito bites. You can’t catch it from other people—it only spreads when a mosquito bites an infected bird and then bites a human.
There are no vaccines or specific medicines to treat West Nile virus. Most people don’t get very sick, but in some cases, it can cause serious health problems.
Symptoms of West Nile Virus
Most people infected with the virus don’t feel sick at all. But others may have symptoms like:
Fever
Headache
Body aches and joint pain
Vomiting or diarrhea
Skin rash
Feeling very tired or weak for a long time
In rare cases, the virus can cause serious problems, such as swelling in the brain or spinal cord. This can lead to:
High fever
Neck stiffness
Confusion or disorientation
Muscle weakness or even paralysis
People who are over 60 years old, or those with other health conditions like diabetes or cancer, have a higher risk of getting very sick.
Where the Virus Has Been Found in Michigan?
So far this year, mosquitoes carrying West Nile virus have been found in several Michigan counties, including:
Bay
Kalamazoo
Kent
Macomb
Midland
Saginaw
Tuscola
Wayne
This shows that the virus is active in many areas of the state—not just in one location.
How to Protect Yourself and Your Family?
You can reduce the risk of mosquito bites by following a few simple steps:
✅ Use insect repellent approved by the EPA. Look for ingredients like DEET, picaridin, or oil of lemon eucalyptus.
✅*Wear long sleeves and pants when outdoors, especially between dusk and dawn, when mosquitoes are most active.
✅ Get rid of standing water around your home. Mosquitoes lay eggs in water that sits in buckets, bird baths, tires, or plant trays.
✅ Make sure window and door screens are in good condition. Repair any holes so mosquitoes can’t get inside.
✅ Use mosquito nets if sleeping outdoors or in a place without screens.
Why This Update is crucial?
West Nile virus is the most common disease spread by mosquitoes in the U.S. Most people won’t get very sick, but a few can get seriously ill, and it’s not always possible to know who will be affected the most.
Now that Michigan has confirmed a human case, it’s a strong reminder to take simple steps to protect yourself and your family from mosquito bites this summer and fall.
