Health officials in Michigan have announced the first human case of West Nile Virus for the year. The individual, a resident of Livingston County, likely contracted the virus while traveling in Nevada, according to the Michigan Department of Health and Human Services.
Emily Dinh, a medical epidemiologist with the state health department, explained, “This patient spent most of their time outside Michigan, where West Nile Virus is prevalent, during their vacation.”
West Nile Virus is primarily transmitted by mosquitoes, and many infected individuals show no symptoms. The health department is actively testing mosquito pools and animals to monitor the virus’s spread. Positive tests for the virus have been reported in mosquitoes in Bay County, Kent County, Ottawa County, Saginaw County, and St. Clair County. Additionally, ten birds have tested positive for the virus.
While most cases of West Nile Virus are asymptomatic, some individuals may experience symptoms such as headaches, fevers, body pains, and fatigue. Severe cases can lead to symptoms like disorientation and seizures, and in rare instances, the virus can cause inflammation of the brain (encephalitis). Those over 60 years old, individuals with serious medical conditions, or weakened immune systems are most vulnerable to severe symptoms.
To reduce the risk of mosquito bites, the Michigan health department advises residents to keep grass trimmed short and eliminate standing water from containers like tires and sinks. They also recommend wearing long sleeves and pants outdoors and using insect repellent.
