St. Louis encephalitis

Saint Louis encephalitis is a disease of the Flaviviridae family that is transmitted by Culex mosquitoes and birds. This disease is commonly found in the New World, such as Canada, Argentina, the United States, and the Caribbean Islands. The majority of the infections caused by Saint Louis encephalitis do not result in a disease or only cause mild illnesses, with symptoms such as fever and headaches. There is currently no vaccine or cure to this disease.
