Getah virus (GETV) is a mosquito-borne and widespread alphavirus which is very closely related to Ross River virus. It is spread through multiple species of mosquitoes. It's distribution ranges from Eurasia to southeast and far eastern Asia, the Pacific islands, and Australasia. Racehorses are often affected. In 1978, outbreaks of GETV infection occurred at two racehorse training centers in Japan.
Clinical signs of the disease are mild and nonlife-threatening. An inactivated vaccine is available for the prevention and control of Getah virus infection in horses in Japan.
Transmission: It is transmitted through the bite of an infected mosquito. There is some evidence to suggest that direct horse-to-horse transmission may occur during outbreaks via nasal discharges that contain considerable amounts of virus.
Geographical Reach: The virus has been reported primarily in Asian countries--Japan, Korea, China, Hong Kong, India and Southeast Asia.
