La Crosse Encephalitis is a rare but serious mosquito-borne illness. Knowing its symptoms, causes, and prevention can help protect you and your family from infection.

What are the main causes of La Crosse Encephalitis?

  • La Crosse Encephalitis is primarily caused by a virus transmitted through the bite of infected mosquitoes, especially the treehole mosquito species.
  • Children are more susceptible because their immune systems are still developing, increasing the risk of severe infection.
  • Environmental factors, such as living near wooded areas with stagnant water, can increase mosquito breeding and virus exposure.

Key symptoms of La Crosse Encephalitis to watch for

  • Early symptoms often include fever, headache, nausea, and vomiting, which can appear within a few days of infection.
  • Severe cases may result in neurological symptoms like seizures, confusion, or muscle weakness, indicating brain inflammation.
  • Fatigue, irritability, and sensitivity to light are common additional signs of La Crosse Encephalitis.
