At least 13 patients have died from coronavirus over 24 hours at a New York hospital

At least 13 patients have died from Covid-19 at Elmhurst Hospital in New York, a statement from a spokesman said.

The deaths of the patients took place over the last 24 hours, but NYC Health and Hospitals/Elmhurst said in a statement that number is consistent with the number of Intensive Care Unit patients being treated there.

"Staff are doing everything in our power to save every person who contracts Covid-19," the statement said.

New York has more than 30,000 of the nation's more than 65,000 coronavirus cases, and 285 of its residents have died from the virus. Elmhurst is at the center of the crisis, the statement said, and staff is working to overcome the overwhelming numbers.

"The frontline staff are going above and beyond in this crisis, and we continue surging supplies and personnel to this critical facility to keep pace with the crisis," the statement said.

"We are literally increasing the effective capacity of the hospital on a daily basis by sending more doctors, nurses, ventilators and PPE to meet demand."

New York has ordered residents to stay at home to curb the spread of the virus and hopefully ease pressures on healthcare systems.
