What comes into focus from disasters such as Harvey is a lack of disaster preparedness compared with pandemics such as the flu, according to Hotez. “We don’t realize that the Gulf Coast is America’s vulnerable underbelly of infectious disease,” he said, referring to a paper he wrote in 2014. The hot and humid region combines high levels of poverty with major transportation hubs, with problems exacerbated by the effects of climate change.
“All of those forces,” he explained Monday, “combine to make the Gulf Coast especially susceptible to infectious and tropical disease.”
