Two human cases of West Nile Virus were confirmed this week in western Iowa. The first case occurred in an adult male from Pottawattamie County, and the second in an older adult Harrison County woman. Several additional cases are also being investigated in southwestern Iowa. The months of standing water resulting from the Missouri River flooding has likely provided favorable conditions for mosquitoes. West Nile virus activity usually peaks in September and October.
