West nile fever

West Nile fever is an acute febrile disease transmitted by West Nile virus through mosquitoes. It mainly infects birds, humans, and mammals such as horses and cattle. Can invade the central nervous system and cause encephalitis. It is endemic in Africa, Southern Europe, the Middle East, Central and Western Asia, and Oceania. The disease caused by West Nile virus infection has not been found in our country, and West Nile virus has not been isolated. However, with the increasing frequency of international exchanges, we are also facing the threat of importing the disease. Clinical manifestations include fever, rash and lymphadenopathy, invasion of the central nervous system, and can produce symptoms of encephalitis.
