More than 1,400 medical workers have volunteered to help nursing homes and hospitals across the city, New York City Mayor Bill de Blasio said at a press conference today.

The volunteers will be divided over 40 hospitals and 40 nursing homes, the mayor said.

There are 535 military nurses, respiratory therapists, physicians assistants, nurse practitioners and pharmacists at NYC Health and Hospitals.

De Blasio also made a plea for anyone that has been diagnosed with Covid-19 and has recovered to give blood so health officials could use the plasma to fight the disease.

As the weather gets better, the New York Police Department and Parks Department are stepping up enforcement citywide, targeting hotspots for complaints and non-compliance, de Blasio said.

There will be fines of up to $1,000 if people ignore the social distancing rules, de Blasio said.

By the numbers: At least 317 people were admitted to the hospital for suspected coronavirus cases across New York City, de Blasio said.

That number is up from 261 people admitted on April 16, the mayor says.

There are at least 849 people in NYC Health and Hospitals ICUs, that number is down from 880 people on April 16.
