What is a common symptom of LaCrosse encephalitis in children?

LaCrosse encephalitis is typically characterized by a relatively mild disease course in children, often resulting in the absence of symptoms, which makes the answer about not showing symptoms frequently the most accurate choice. In many cases, children infected with the virus can exhibit only mild clinical signs or remain entirely asymptomatic, which can sometimes make it challenging to diagnose the condition early.

While other symptoms like high fever, intense headache, and stiff neck can occur in some cases, they are not universally observed. The tendency for many infected children to either show very mild symptoms or none at all is a notable aspect of LaCrosse encephalitis, differentiating it from other forms of viral encephalitis that might present with more prominent symptoms early on. This asymptomatic nature underscores the importance of awareness and vector control strategies in managing the disease, particularly since it's transmitted by mosquitoes, and children are often more susceptible to these vectors during outdoor activities.
