The World Mosquito Program is about to begin building on a mass rearing facility—the largest on the planet—in Curitiba. “And we consider that can enable us to primarily cowl most of city Brazil inside the subsequent 10 years,” Callahan says.
There are additionally different mosquito-based approaches within the works. The UK firm Oxitec has been offering genetically modified “pleasant” mosquito eggs to Indaiatuba, Brazil, since 2018. The bugs that hatch—all males—don’t chunk. And once they mate, their feminine offspring don’t survive, lowering populations.
One other firm, Forrest Brasil Tecnologia, has been releasing sterile male mosquitoes in elements of Ortigueira. When these males mate with wild females, they produce eggs that don’t hatch. From November 2020 to July 2022, the corporate recorded a 98.7% decline within the Ades aegypti inhabitants in Ortigueira.
Brazil can be engaged on efforts to supply its residents with higher immunity, vaccinating probably the most susceptible with a brand new shot from Japan and dealing on its personal home-grown dengue vaccine.
None of those options are a fast repair. However all of them present some hope that the world can discover methods to combat again whilst local weather change drives dengue and different infections to new peaks and into new territories. ““Instances of dengue fever are rising at an alarming fee,” Gabriela Paz-Bailey, who focuses on dengue on the US Facilities for Illness Management and Prevention, advised the Washington Publish. “It’s changing into a public well being disaster and coming to locations which have by no means had it earlier than.”

We’ve written concerning the World Mosquito Program earlier than. Right here’s a 2016 story from Antonio Regalado that checked out early pleasure and Invoice Gates’ backing of the challenge.
That very same 12 months we reported on Oxitec’s early work in Brazil utilizing genetically modified mosquitoes. Flavio Devienne Ferreira has the story.
And this story from Emily Mullin seems to be at Google’s sister firm, Verily. It constructed a robotic to create Wolbachia-infected mosquitoes and started releasing them in California in 2017. (The challenge is now known as Debug).
