Overview
St. Louis encephalitis is one of the most common mosquito-transmitted human pathogens in the United States. St. Louis encephalitis virus is a flavivirus that was first identified in St. Louis, Missouri in 1933. St. Louis encephalitis is diagnosed based on symptoms, physical findings, laboratory testing, and the possibility of exposure to infected mosquitoes. There is no specific treatment for St. Louis encephalitis; care is based on symptoms. Steps to prevent infection with St. Louis encephalitis virus include use of insect repellent, protective clothing, and staying indoors while mosquitoes are most active. While periodic St. Louis encephalitis epidemics have occurred only in the Midwest and Southeast, St. Louis encephalitis virus is distributed throughout the lower 48 states
Causes
St. Louis encephalitis virus is a member of the genus Flavivirus, family Flaviviridae. Other similar diseases are West Nile virus, eastern equine encephalitis, western equine encephalitis, and La Crosse encephalitis. SLEV has a single-stranded, positive-sense RNA genome. The virus particles are spherical and have a diameter of 40 nm.
Epidemiology and Demographics
4,651 cases have been reported throughout the United States from 1964 to 2005. Over this time period, the central and eastern states have reported the largest number of cases. In temperate areas of the United States, St. Louis encephalitis cases occur primarily in the late summer or early fall. In the southern states, where the climate is milder, St. Louis encephalitis can occur year round.
