What are common symptoms of the LaCrosse encephalitis?

LaCrosse encephalitis is a viral infection that primarily affects the central nervous system and is transmitted by mosquito bites. Common symptoms typically include fever, headache, nausea, vomiting, and lethargy. The presence of fever is significant, as it indicates the body's response to infection. The illness can lead to more serious complications such as seizures or encephalitis, particularly in children.

While other symptoms like severe headache and rash, muscle pain, and fatigue may occur, the hallmark of the initial phase of the illness is generally associated with fever, making it a critical symptom for identification. Understanding that fever is one of the primary responses to the viral infection is essential in recognizing and diagnosing LaCrosse encephalitis. This symptom is often the first sign that leads to further investigation and treatment.
