Residents of Hillsborough and Hernando counties are being urged to take precautions against mosquito bites in light of a suspected case of eastern equine encephalitis in Hillsborough and West Nile Virus in Hernando. Hillsborough health officials released few details about the latest encephalitis case, only saying that it had positive laboratory evidence of the virus in a county resident. Two deaths from Eastern equine encephalitis were reported in Hillsborough County in July, which is unusual since only five to 10 such cases are reported annually in the U.S. The Hernando case involves two chickens that tested positive for West Nile Virus. Both diseases are spread through infected mosquitoes. Symptoms of both include headaches, fever, convulsions and coma. To reduce the risk of being bitten, health officials suggest people avoid being outside during dusk and dawn hours, when mosquitoes are seeking blood. They also suggest wearing clothing that covers most of your skin when outdoors and using mosquito repellents.
