In a troubling uptick of infectious disease incidents in Knox County, six children have recently been hospitalized after contracting the La Crosse virus, as reported by the Knox County Health Department. Kelsey Wilson with the department disclosed that all these cases surfaced within the last nine weeks, affecting children under the age of 12 — marking the highest incidence rate in the county since 2020. In a statement obtained by WVLT, Wilson cautioned that the mosquito season persists and highlighted the importance of vigilance in the community.
La Crosse virus is typically transmitted through the bite of an infected Aedes mosquito, with symptoms varying widely among those affected. According to the WATE report, the Knox County Health Department stated, that the majority of those infected do not exhibit any symptoms. In instances where symptoms do develop, individuals may experience fever, headache, nausea, and vomiting. The more severe cases, which tend to occur predominantly in children under 16, can lead to hospitalization and possibly result in encephalitis — a severe brain inflammation.
According to the health department, while severe cases generally recover with proper care, up to 15% can suffer from significant neurological complications. In light of the ongoing outbreak, officials urge community members to take extensive preventive measures against mosquito bites. Practical steps include using insect repellents, treating clothing with repellents like permethrin, wearing long sleeves and pants when in grassy or wooded areas, and employing mosquito netting for strollers and baby carriers. An additional significant measure is the reduction of standing water in yards where mosquitoes can breed, including turning over water-holding items such as buckets and toys once a week.
In the event of noting any new neurological symptoms in children, the department emphasizes the urgency of seeking immediate medical care. Kelsey Wilson explicitly stated, "If you notice any new neurological issue in your child, seek emergency care," as reported by WVLT. The Knox County Health Department remains vigilant and urges the community to stay informed and proactive in curbing the spread of the La Crosse virus.
