Summary:
- Mosquitoes in South America are becoming resistant to insecticides, making it more difficult to control the spread of malaria.
- Researchers found that mosquitoes in Brazil, Colombia, and Venezuela have developed resistance to multiple insecticides commonly used to control them.
- This resistance could undermine efforts to prevent and treat malaria, a serious disease that can be deadly if left untreated. Controlling mosquitoes is a key part of malaria prevention.
