La Crosse virus confirmed in Uhrichsville resident
The Tuscarawas County Health Department confirmed a case of La Crosse virus July 17 in a 66-year-old man from Uhrichsville — the first case in a county resident since 2021.
The man developed viral meningitis and was hospitalized but has since returned home to recover.
“La Crosse virus is rare in Ohio, and we don’t want anyone to panic,” said Katie Seward, MPH, Tuscarawas County health commissioner. “We are simply asking Uhrichsville-area residents to be careful and talk with their medical providers about any health concerns.”
La Crosse virus is transmitted through the bite of an infected Aedes triseriatus (Eastern tree hole) mosquito. These mosquitoes are typically found in wooded areas and lay eggs in natural water pools such as tree holes, as well as man-made containers like discarded tires. The mosquito is also a known vector for canine heartworm.
In response, the health department conducted mosquito control activities in Uhrichsville on Friday, July 18. Additionally, mosquito spraying was scheduled from 8 to 11 p.m. Monday, July 21. In case of rain, spraying will be postponed.
The health department accepts requests for no-spray areas. To request one, call the TCHD Bureau of Environmental Health Services at 330-343-5550 or email eh@tchdnow.org.
Symptoms
According to the Centers for Disease Control and Prevention, many people infected with La Crosse virus experience no symptoms. Those who do may notice symptoms five to 15 days after being bitten:
– Fever
– Headache
– Nausea
– Vomiting
– Lethargy
Severe illness, most common in children under 16, may include:
– Seizures
– Coma
– Paralysis
– Long-term neurological complications
Fatalities are rare, occurring in fewer than 1% of cases. There is no vaccine or antiviral treatment for La Crosse virus.
Prevention tips
The Tuscarawas County Health Department encourages residents to take the following steps to reduce mosquito activity:
– Use insect repellent outdoors and wear long sleeves, pants and socks when possible. Repellent may be sprayed on clothing for added protection.
– Repair window and door screens. Use air conditioning if available.
– Eliminate standing water from containers such as flowerpots, gutters, pool covers, pet dishes, tires and birdbaths at least every three days.
– Fill tree holes with dirt, sand or insulation cement to prevent mosquito breeding.
