S.D. reports three human West Nile cases The Department of Health announced July 27 three more human West Nile Virus cases, one blood donor detection, two positive mosquito pools, and one positive bird. Detections include:
* Positive human WNV, Beadle County, 40-49 age group;
* Positive human WNV, McCook County, 50-59 age group;
* Positive human WNV, Charles Mix County, 70-79 age group;
* Blood donor detection, Minnehaha County;
* Positive blue jay, Brown County;
* Two positive mosquito pools, Minnehaha County (Culex tarsalis, Culex pipiens.)
Each of the three new human cases has West Nile Fever, which is a flu-like illness with fever, headache, muscle weakness, possible rash, swollen lymph glands, and muscle aches. The detections in Beadle, Brown and McCook represent the first detections for those counties this season.
South Dakota has now reported a total of seven human West Nile cases and two asymptomatic blood donor detections for the season. Previous human cases have been reported in Aurora, Davison, Jackson and Pennington counties. The earlier blood donor detection was reported in Hand County.
According to the Department of Health, the new detections are clear evidence that the virus is being transmitted throughout the state and that South Dakotans should be taking personal precautions to protect themselves from mosquito bites:
* Use DEET based mosquito repellents.
* Screen all windows and doors and keep screens in good repair.
* Wear shoes, socks, long pants and a long-sleeved shirt to limit mosquito exposure.
* Limit time outdoors at dusk and dawn when mosquitoes are most active.
* Eliminate standing water that gives mosquitoes a place to breed.
* The elderly and pregnant women should be especially mindful to take precautions.
