The number of Culex tarsalis mosquitoes, the carriers of West Nile Virus, is on the rise in South Dakota.
State epidemiologist Lon Kightlinger says that from the first week of July to the second, there was a substantial increase in Culex mosquitoes and also a rise in the number testing positive for West Nile.
Kightlinger says that historically 90 percent of South Dakota's West Nile Virus cases occur from mid-July to mid-September.
So far this year, South Dakota has reported four human cases of West Nile and 23 positive mosquito pools.
