The bacteria that can fight Zika


Health authorities in Brazil and Colombia will infect mosquitoes with a bacteria that should be able to prevent them from contaminating humans, the bacteria, Wolbachia, must prevent the spreading of Zika and some other viruses. Mosquitoes from Brazil and Colombia will be infected in 2017.

These bacteria are naturally found in some species of mosquitoes and can decrease the chance of transmission of the viruses to humans, said Reuters.

So, the infected mosquitoes will be freed in the large cities of Rio de Janeiro, Brazil, and Antioquia, Colombia, next year 2017. The plan is that these procreate with mosquitoes that already carry the Zika virus. Creating a new generation of infected mosquitoes that could not infect humans.

This solution has been the subject of tests and studies in the last years by researchers who are at the service of the Program to Eliminate Dengue, which was created in Australia. Scientists have found a way to introduce the bacteria to the species of the Aedes aegypti mosquito, primarily responsible for transmitting dengue, yellow fever, Chikungunya and more recently, Zika.

“The use of Wolbachia is a possible innovative and sustainable solution to reduce the impact of this outbreak the world and especially among the poorest people,” said Secretary of British international development Priti Patel, according to Reuters.
