Bac­te­ria

Bloomberg Businessweek (North America) - - Global Economics -

Fe­male mos­qui­toes are in­fected with Wol­bachia, a bac­terium that blocks trans­mis­sion of the dengue virus and may also stop Zika. A re­search non­profit has tested it in Aus­tralia since 2011—with smaller tests in Brazil, Colom­bia, and South­east Asia.

Ad­van­tages The method could yield long-term cost sav­ings be­cause in­fected mos­qui­toes spread bac­te­ria to each other.

Draw­backs There are no large-scale fa­cil­i­ties in af­fected ar­eas. More re­search is needed on the bac­terium’s ef­fec­tive­ness.
