The Arkansas Health Department says the state has now confirmed its eleventh case of West Nile virus this year. The latest case is in Lonoke County. The human cases have been reported among ten counties -- Craighead, Izard, Union, Greene, Jefferson, Lonoke, Ouachita, Pope, Pulaski and Sebastian. No human deaths in Arkansas have been attributed to West Nile virus this year. The virus has been found in birds in a total of 28 counties. The disease is carried by birds and spread by mosquitoes. The Health Department says homeowners should dispose of water-holding containers and discarded tires, and make sure roof gutters drain properly.
