The Virus looks like a complicated chemical machine, designed to kill humans. West Nile virus (WNV) is a neurotropic flavivirus that cycles between mosquitoes and birds but that can also infect humans, horses, and other vertebrate animals. In most humans, WNV infection remains subclinical. However, 20%–40% of those infected may develop WNV disease, with symptoms ranging from fever to meningoencephalitis. It is now present in Israel, carried by mosquitoes. Don't we have enough troubles that this thingie comes to make our life even more dangerous?
