With Italy remaining in first place for infections (144), and deaths, 39 cases have been reported in Greece, 2 in Austria, 2 in Romania, and 1 in Slovakia. Currently, experts are also monitoring the animals, with veterinary surveillance focused on horses, mosquitoes, resident and wild birds.

Positive tests are also underway in the provinces of Alessandria, Asti, Oristano and Cagliari.

What is West Nile Virus

West Nile fever is caused by a virus of the Flaviviridae family isolated for the first time in Uganda, in the district called West Nile, and spread to Africa, Western Asia, Europe, Australia and America. Most of the infected people – explains the website of the Istituto Superiore di Sanità (Iss) – do not show any symptoms. Of the symptomatic cases, about 20% have mild symptoms such as fever, headache, nausea, vomiting, and rashes.
