Un batterio innocuo per l'uomo potrebbe essere usato per bloccare la trasmissione del virus Zika da parte delle zanzare responsabili del passaggio della malattia agli esseri umani.
Il microrganismo, identificato da ricercatori nel Wisconsin, è in grado di "disarmare" le zanzare e impedire la trasmissione del virus. È già impiegato nella lotta alla diffusione della febbre dengue in diverse regioni.
La dengue ha molti aspetti in comune con l'infezione provocata dal virus Zika e gli scienziati si dicono ottimisti sulla possibilità di arginare la malattia che negli ultimi sei mesi si è diffusa in particolare in America del Sud.
