NEW ORLEANS (AP) — Nearly 15 years after Hurricane Katrina, New Orleans is facing another test of its ability to prepare for potential disaster. The city is one of the nation’s hot spots for coronavirus. As of Friday, New Orleans and neighboring Jefferson Parish had recorded more than 80 of the state’s 119 COVID-19 deaths and more than 1,700 of the state’s 2,700-plus known cases. Medical experts and government officials speculate that the annual Mardi Gras celebration in late February was a factor. A convention center that sheltered Katrina refugees is about to become an emergency hospital for a potential overflow of virus patients.
