Narrative Information

Mayo Clinic: “Encephalitis (en-sef-uh-LIE-tis) is inflammation of the brain. There are several causes, but the most common is viral infection. Encephalitis often causes only mild flu-like signs and symptoms — such as a fever or headache — or no symptoms at all. Sometimes the flu-like symptoms are more severe. Encephalitis can also cause confused thinking, seizures, or problems with senses or movement. Rarely, encephalitis can be life-threatening. Timely diagnosis and treatment are important because it’s difficult to predict how encephalitis will affect each individual.

“Mosquito-borne viruses. These viruses can cause infections such as West Nile, La Crosse, St. Louis, western equine and eastern equine encephalitis. Symptoms of an infection might appear within a few days to a couple of weeks after exposure to a mosquito-borne virus….” (Mayo Clinic. Encephalitis.)
