Molti paesi disinfettano le strade, i marciapiedi e i mercati per contrastare il coronavirus. Questa pratica non è tuttavia efficace, spiega in un comunicato l'Organizzazione mondiale della sanità (OMS).
Questi spazi esterni non sono infatti considerati serbatoi di infezione per il Covid-19. Lo sporco e i detriti fungono inoltre da "copertura", rendendo inoperoso la soluzione usata.
Le sostanze usate, aggiunge l'OMS, sarebbero addirittura dannose per la salute umana: gli spray adoperati possono provocare irritazione agli occhi e alla pelle. Non sono inoltre esclusi disturbi gastrointestinali, come nausea e vomito.
