At least 24 states reported over 100 new cases of the coronavirus on Thursday. The worst outbreak continues to be in New York, which reported nearly 6,500 new cases. 

Medical facilities were running low on ventilators and protective masks and were hampered by limited diagnostic testing capacity. 

The number of US cases of coronavirus reached more than 81,300, the Reuters tally showed. China was second with more than 81,200 cases, and Italy third with over 80,500 cases. 

Nearly 1,200 people in the United States have died from COVID-19, which has proven especially dangerous to the elderly and people with underlying chronic health conditions, according to a running tally based on reports from state and local public health authorities.

An expected shortfall of ventilators - machines that support respiration for people who have lost the ability to breathe on their own - was substantial, as a surge of cases overwhelms New York hospitals, New York Governor Andrew Cuomo told a news conference. 

“Any scenario that is realistic will overwhelm the capacity of the healthcare system,” he said. “The number of ventilators we need is so astronomical - it’s not like they have them sitting in the warehouse,” Cuomo added. “There is no stockpile available.” 

At least one New York hospital has begun a trial of sharing single ventilators between two patients.

While New York was the coronavirus epicenter in the United States this week, Louisiana could be the next. In New Orleans, the state’s biggest city, Mardi Gras celebrations last month were believed to have fueled the outbreak.
