The first detection of West Nile Virus (WNV) this season has been reported in Minnehaha County, South Dakota. Dr. Joshua Clayton, the State Epidemiologist for the Department of Health, emphasized the importance of protecting oneself against mosquito bites due to the rural nature of the state and increased outdoor activities during summer. He advised using bug spray or limiting activities between dusk-to-dawn hours to significantly reduce infection risk.
To prevent mosquito bites and lower WNV risk, residents are encouraged to apply mosquito repellents such as DEET or picaridin to clothes and exposed skin. Wearing pants and long sleeves in the evening can also help limit exposure. It is recommended to avoid spending time outdoors from dusk to midnight when mosquitoes are most active, particularly Culex tarsalis, which is the primary carrier of WNV in South Dakota.
Residents should also remove standing water where mosquitoes breed by regularly changing water in birdbaths and pet dishes and draining flowerpots and garden containers. Supporting local mosquito control efforts is another way to mitigate risks.
Personal precautions are crucial for individuals at high risk for severe illness from WNV, including those over 60 years old, pregnant women, transplant patients, and individuals with cancer, diabetes, hypertension, or kidney disease. Symptoms such as fever with headache, muscle aches, or rash should prompt a consultation with a physician.
Since 2002, South Dakota has reported more than 2,864 human cases and 54 deaths related to WNV. Every county in the state has recorded cases.
