Another dead bird in eastern Iowa is confirmed infected with West Nile virus. The latest case is in Clinton County, where a crow was found on Monday in the city of Clinton and tested positive. State health department spokesman Kevin Teale says there’ve been no human cases in Iowa. Teale recommends people take proper precautions against mosquitoes as the virus is likely to spread as the mosquitoes spread. The virus has been found in five dead birds in recent weeks in four counties: Clinton, Scott, Johnson and Linn counties — all in eastern Iowa. While most people aren’t affected by West Nile, Teale says in some cases, it CAN be fatal.
