La zanzara tigre non può trasmettere il nuovo coronavirus. Lo aveva già spiegato l’Organizzazione mondiale della sanità e martedì lo hanno ribadito anche le autorità cantonali ticinesi.
Per quanto possa essere fastidioso, questo fortunatamente piccolo insetto non rischierà di aggravare l’emergenza sanitaria attuale, questo perché il virus responsabile del Covid-19 non ha le capacità di replicarsi all’interno delle zanzare.
Solo gli arbovirus possono essere trasmessi tramite gli insetti, come ad esempio il virus Zika e quello che causa la febbre Dengue. Per quanto concerne i coronavirus, invece, nessuno di quelli studiati finora ha le capacità di farlo.
“Prima che possa essere trasmesso attraverso le zanzare, un virus deve sviluppare un’alta specializzazione e un grande adattamento al vettore di trasmissione. È un processo che dal punto di vista evolutivo può durare milioni di anni”, spiega Mauro Tonolla, responsabile del laboratorio di microbiologia applicata della SUPSI.
Tuttavia, a partire da maggio la lotta alla zanzara tigre si intensificherà per limitarne al massimo la diffusione.
