St. Louis Encephalitis Virus

Saint Louis Encephalitis Virus is available from ZeptoMetrix. Saint Louis Encephalitis Virus (SLEV) gets its name from a 1933 outbreak in St. Louis, Missouri and the neighboring St. Louis counties. Belonging to the virus family Flaviviridae, SLEV typically gets passed to humans by an infected mosquito. It can cause side effects such as fever, nausea, fatigue and extreme headaches. With older adults, a severe infection has been known to cause inflammation of the brain, also known as encephalitis.
