A Hughes County resident in the 30 to 39 age group is South Dakota’s first West Nile virus (WNV) case of the year, the Department of Health reported today.

Since its first human WNV case in 2002, South Dakota has reported more than 1,700 cases and 26 deaths.

“Peak transmission for West Nile in South Dakota occurs from July through early September but cases have also occurred in early June so this is not unexpected,” said Lon Kightlinger, State Epidemiologist for the Department of Health. “This is a reminder that we need to protect ourselves and our families by using repellent and limiting our time outside when mosquitoes are active.”

The department recommends the following personal precautions to prevent mosquito bites and reduce the risk of WNV:


* Use mosquito repellents containing DEET, picaridin, oil of lemon eucalyptus, or IR3535.

* Wear shoes, socks, long pants and a long-sleeved shirt to limit mosquito exposure.

* Limit time outdoors from dusk to midnight when Culex mosquitoes are most active.

* Eliminate standing water that gives mosquitoes a place to breed.

* Support local mosquito control efforts.

Personal precautions are particularly important for those over 50, pregnant women, transplant patients and people with other underlying medical conditions. People with a severe or unusual headache should see their physician. Those with diabetes are also at higher risk of complications from WNV and should take precautions.
