Another reason to declare war on mosquitoes has been discovered by the Shasta Mosquito and Vector Control District. A sample of 38 mosquitoes in Anderson has tested positive for St. Louis Encephalitis. The disease, which can result in inflammation of the brain, has the same early symptoms as West Nile Virus, including high fever, severe headache, confusion or a stiff neck. St. Louis Encephalitis has not been seen in Shasta County since 1972. There have already been two human West Nile cases confirmed in Shasta County this season, and a record number of West Nile positive mosquito samples have been found. Everyone should check their yards and eliminate standing water where mosquitos can breed. Heavy mosquito problems can be reported to 365-3768 or shastamosquito.org.
