Don’t let your guard down against the West Nile virus. This is the appeal launched yesterday by the Ausl in light of the multiplication of cases in the region. The infection, transmitted to humans by the common mosquito, proceeds asymptomatically in most cases, but can also present itself with fever, headache, and other mild symptoms with spontaneous resolution or, sporadically, manifest itself with more serious forms affecting the central nervous system (meningitis, meningoencephalitis). The virus, which can be dangerous especially in already debilitated patients, is endemic, that is present in a stable manner, in our Region and in those of the Po valley. Its multiplication cycle develops between some bird species and common mosquitoes. Humans, like horses, are occasionally infected by mosquito bites and are unable to transmit the infection to other mosquitoes or to other people.
“This year the circulation of the West Nile virus began slightly earlier than in previous seasons – explain from the Ausl – and to date cases have been reported in the provinces of Piacenza, Parma, Reggio Emilia, Modena and Ferrara. positivity in mosquito pools have already been found “.
