Mosquito borne illnesses being reported in the area
Three children in our community have been diagnosed with Lacrosse viral disease. This disease is a viral illness spread by the bite of a mosquito. All children were transported to Akron Children’s Hospital and children were hospitalized for encephalitis (swelling of the brain). A fourth hospitalized child is currently under investigation. All children have recovered.Due to the seriousness of these symptoms, the Holmes County Health Department is notifying the community about the cases and information about the disease. Wayne and Holmes counties are two of the highest reporters for cases of Lacrosse viral disease (first and fourth respectively) in the state of Ohio. The last reported case for Holmes County was in 2008.
These cases are an unfortunate reminder that we all need to take precautions to prevent mosquito bites. Residents can help reduce this type of mosquito from breeding and biting by following these recommendations:
• Wear insect repellents that contain DEET
• Remove any containers that can hold water (even small quantities)
• Keep gutters clean and in good repair; allow drainage ditched to flow
• Repair leaky outdoor faucets and change the water in bird baths and pet bowls at least twice a week; and
• Check window and door screens.
The La Crosse encephalitis virus can cause meningitis and/or encephalitis. Cases of Lacrosse viral disease are generally reported in August and September. The unusual wet spring followed by a hot summer can cause mosquito populations to be higher than normal increasing the risk of human exposure to infected mosquitoes. The mosquito that transmits the LAC virus breeds in tree holes in forested areas and in containers that have collected water. The tree hole mosquito bites during the day, when people are most likely to be involved in outside activities.
Most people who become infected do not develop any symptoms. If people do become ill, symptoms usually occur about five to 15 days after the mosquito bite. Persons who become ill usually only have mild flu-like symptoms such as fever, headache, nausea, and vomiting. In some cases, a person can develop viral meningitis or encephalitis with changes in mental status or consciousness, paralysis, seizures, and possibly death. Cases are rarely fatal. Most people with La Crosse encephalitis will make a full recovery; some persons may experience side effects for several years after they recover. The majority of severe cases occurs in children under 16 years of age but can occur in the elderly. Cases can be fatal although rare. No treatments exist for the virus. Doctors can use supportive care to treat the symptoms of this disease.
