South Dakota reports first West Nile virus detection of the season The Department of Health today reported South Dakotaâ�?�?s first West Nile virus detection of the year, a Corson County resident in the 30 to 39 age group. In 2007, the first human case was reported June 5 and a total of 208 cases and six deaths were reported for the year South Dakotaâ�?�?s first case of human WNV was reported in 2002. Since then, 1,677 cases and 26 deaths have been reported in the state. Since 2004, as part of its WNV response, the state has awarded more than $3 million in grants to cities, counties and tribes across the state for mosquito control. The department recommends the following personal precautions to prevent mosquito bites and reduce the risk of WNV: â�?¢ Use�? mosquito repellents containing DEET, picaridin, oil of lemon eucalyptus, or IR3535. â�?¢ Wear shoes, socks, long pants and a long-sleeved shirt to limit mosquito exposure.�? â�?¢ Limit time outdoors�? from dusk to midnight when�? Culex mosquitoes are most active. â�?¢ Eliminate standing water that gives mosquitoes a place to breed. â�?¢ Support local mosquito control efforts. Personal precautions are particularly important for the elderly, 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.
