What If We Killed Every Mosquito On Earth?
AsapSCIENCE・2 minutes read
A mosquito factory in Brazil is releasing 5 billion infected mosquitoes to fight deadly diseases like malaria, dengue, and Zika, with the potential to revolutionize disease prevention on a large scale by reducing disease transmission rates significantly. Scientists have used Wolbachia bacteria to prevent disease transmission, with successful deployments in countries like Indonesia and Colombia showing promising results in reducing the spread of dengue fever.
Insights
- Deploying Wolbachia-infected mosquitoes can significantly reduce disease transmission rates, with successful trials in Indonesia and Colombia showing a protective efficacy of up to 97% against dengue fever.
- While eradicating mosquitoes may not directly impact humans, the diseases they spread affect millions annually, making innovative approaches like using Wolbachia-infected mosquitoes crucial in combating deadly illnesses like malaria, dengue, and Zika.

Brazil's Mosquito Factory: Revolutionizing Disease Prevention
- A mosquito factory in Brazil is set to release 5 billion infected mosquitoes across the country, a groundbreaking scientific endeavor aimed at combating the deadliest animal to humans, mosquitoes, known for spreading diseases like malaria, dengue, and Zika.
- While some may question the necessity of mosquitoes, an analysis by Nature Journal suggests that their eradication wouldn't significantly impact humans, as few species rely solely on them, but the diseases they spread affect millions annually.
- Scientists have harnessed a bacteria called Wolbachia to prevent disease transmission by mosquitoes, allowing infected mosquitoes to outcompete pathogens like the dengue virus, ultimately reducing disease transmission rates significantly.
- Deployments of Wolbachia-infected mosquitoes in various countries have shown promising results, with a 77.1% protective efficacy in Indonesia and a 95-97% reduction in dengue fever in Colombia, showcasing the potential to revolutionize disease prevention on a large scale.
