No humans have yet been infected this year, but a sample of mosquitoes collected by the Metropolitan Mosquito Control District has tested positive for the deadly West Nile virus.
KARE 11 reports that the MMCD collects mosquitoes as part of its annual West Nile virus risk reduction program. The infected insects were found in Carver County.
This spring's wet conditions followed by hot weather create the kind of conditions that can help spread the mosquito species responsible for the disease within the bird population. MMCD tracks reports of dead birds throughout the metro area. It also sprays and drops granules to control the mosquito population.
On Tuesday, the Sioux Falls Argus Leader reported that a Buffalo County child became South Dakota’s first human West Nile virus case. The state Health Department did not release the child's name, age or condition.
