	'''Saint Louis encephalitis''' ([[SLE]]) is a disease caused by the [[Saint Louis encephalitis virus]] (SLEV), a member of the [[Flavivirus]] family. It is named after the city of [[Saint Louis, Missouri]], where the virus was first identified in 1933. The disease is primarily spread through the bite of an infected [[mosquito]], and is found throughout the United States, particularly in the Midwest and South.
