Semliki Forest virus
The Semliki Forest virus was isolated from mosquitoes in the Semliki Forest in 1942. It can cause disease in both animals and man. It’s an Alphavirus found in central, eastern, and southern Africa. It is a positive-stranded RNA virus.
It is spread mainly by mosquito bites and infects mammals through inhalation or gastrointestinal exposure. The virus can cause lethal encephalitis in rodents; however, only one fatal infection has been reported in humans. This patient was immunodeficient and exposed to large amounts of the virus in the laboratory. The virus has been used extensively in biological research as a model of the viral life cycle.
