A British biotechnology company is betting on a solution to Brazil's surging dengue cases, involving the release of genetically modified mosquitoes to reduce the viral infection's spread. Fueled by a hot rainy season, more than 973,000 likely dengue cases have been detected in Brazil so far this year.

In a novel approach to combat the escalating dengue fever crisis in Brazil, a British biotechnology firm has launched a project involving the release of genetically modified mosquitoes. This initiative aims to curtail the spread of the viral infection, which has seen a significant increase in recent times. The initiative comes in response to a troubling surge in dengue cases across Brazil, with over 973,000 likely cases reported so far this year. The hot rainy season in the region has been identified as a contributing factor to this spike, creating conducive breeding conditions for the Aedes aegypti mosquito, the primary vector for dengue transmission.



Modified mosquitos deployed in Brazil to fight dengue surge

As Brazil confronts a massive dengue outbreak, the city of Susano hopes part of the solution is inside these boxes. Fueled by a hot, rainy season, more than 973,000 likely dengue cases have been detected in Brazil so far this year. The boxes contain a version of the male Aedes aegypti mosquito developed by British biotechnology company Oxitec. The modified mosquitoes carry a gene that kills female offspring before they reach maturity. Only female mosquitoes bite and transmit diseases. The modified mosquitoes stay inside the box for about 10 days before coming out, says Oxitec's Natalia Ferreira. When we release the Aedes dobem in a certain neighborhood and compare the mosquito population with that of a neighborhood where it was not used, we always have more than 90% suppression of the population. In other words, the treated neighborhood has 90% fewer mosquitoes than the neighborhood where there was no release. Susano was among the cities using the solution after declaring a state of emergency earlier this month. The city's mayor said he hopes the next measurement will show a reduction in cases by 20% so the emergency can be lifted. According to Brazil's health ministry, 195 people died because of the disease, while hundreds of cases remain under investigation.
