Grayson Brown, Ph.D., executive director of the Puerto Rico Vector Control Unit and a past president of the Entomological Society of America, reports that conditions in Puerto Rico are ripe for a potential dengue outbreak, as recent earthquakes have driven residents out of their homes, increasing their exposure to mosquitoes. The PRVCU is working with ESA and other organizations to quickly procure approximately 5,000 bed nets to help protect residents from mosquitoes.
