Meanwhile, smelly socks are being tested in Tanzania as way to prevent malaria – and working.
Scientists think the musky odor of human feet can be used to attract and kill mosquitoes that carry deadly malaria. The Gates Foundation announced on Wednesday that it will help fund one such pungent project in Tanzania.
If they can be cheaply mass-produced, the traps could provide the first practical way of controlling malaria infections outside. The increased use of bed nets and indoor spraying has already helped bring down transmissions inside homes.
