Africas virus spread via climate change
West Nile virus is a virus belonging to the "Alphavirus" family that is transmitted through the common Culex mosquito. It is considered one of the viruses that are now beginning to spread in Europe, especially in Italy and Greece, with 468 cases recorded so far. Most cases are asymptomatic, but approximately 20% may show symptoms such as fever, headache, and limb pain within 14 days of infection. In rare cases, it can develop into encephalitis or meningitis, which can be fatal in 5-10% of cases. The virus is transmitted from infected birds to humans through bites, particularly when temperatures rise and water is available, which promotes mosquito breeding and spreads the virus. There is no specific vaccine or treatment, so protective measures are advised, such as wearing long clothing, using mosquito nets, and reducing water accumulation in gardens to prevent mosquito breeding.
