Recruiting a bacterial ally that infects mosquitoes has led to huge reductions in cases of dengue fever, trials around the world show.
Wolbachia bacteria make it harder for the insects to spread the virus, rather than kill them off.
Researchers say the findings are a “big deal” with cases falling by more than 70% in field trials.
New ways of controlling dengue are urgently needed as cases have exploded worldwide in the past 50 years.
