Florida has a dengue problem. More mosquitoes may solve it – PBS NewsHour

Judy Woodruff:

A milestone development today in the fight against malaria. The World Health Organization endorsed the widespread use of a vaccine aimed at stemming the effects of malaria, particularly in sub-Saharan Africa.

An estimated 400,000 people, the majority of them children, die from the parasitic disease each year. The new vaccine, which requires four shots, reduced the number of cases by 30 percent. Malaria is transmitted by the anopheles mosquito, making it the most deadly animal on the planet.

Miles O’Brien looks at efforts to tackle other diseases carried by a different breed of lethal mosquitoes. In most cases, there are no vaccines and precious few ways to control the mosquito population.

His story begins in the Florida Keys, where scientists are testing a way to kill mosquitoes with mosquitoes.
