We move to the danger on the front lines. Doctors and nurses warning their hospitals are filling up fast. Some hospitals using lobbies to handle the overflow of patients. Nurses upset about critical shortages of masks, gloves and protective equipment. Here's ABC's Trevor Ault. Reporter: Tonight doctors and nurses taking us inside the pandemic. Our icus are full. Our floors are full. The emergency room is full. We have a lot of patients who are admitted already but simply don't have a place to go. We just had our third death this morning. One of the patients, the husband was calling to get -- check up on her and she passed as he was on hold on the phone. Reporter: Michigan's governor saying the situation in Detroit is getting worse by the minute announcing a huge shipment of more than 100,000 masks that she says will help them get through this weekend.

This building has been converted into a hospital in record time in order to open tomorrow. There will be 3,000 beds used to treat patients who don't have covid-19.
