Health officials in Ross County have confirmed the presence of La Crosse virus in a mosquito sample collected in Colerain Township. This detection serves as a reminder for residents to implement measures to prevent mosquito bites and eliminate potential breeding grounds.
Although no human infections have been documented in Ross County, the Ohio Department of Health reports that the state experiences approximately 20 La Crosse virus cases each year, which is more than any other state. The virus is transmitted by the Eastern treehole mosquito, a species active during daylight hours.
Most individuals infected with the La Crosse virus show no symptoms. However, some may develop fever, headache, nausea, vomiting, or fatigue. Severe cases, particularly in children under 16, can lead to encephalitis, an inflammation of the brain. Residents can obtain mosquito larvicide tablets from the Ross County Health District for standing water that cannot be emptied.
