West Nile scarce in S.D.

SIOUX FALLS — There’s plenty of water and plenty of mosquitoes, but surprisingly low evidence of the West Nile virus in South Dakota, apparently because the sometimes-deadly disease didn’t get a foothold in the bird population this summer.
Only four human West Nile infections have been reported. Trapping and testing have found no infected mosquito pools, although traps collect only a tiny percentage of the vector mosquito population available to transmit the disease among birds and from birds to humans.
