He is asthmatic and has a heart issue which was being investigated by his GP when this all blew up.
He is dealing with CV patients every single day and has been writing extra shifts and because people are off sick. There isn't enough PPE to go around and people are stealing gloves and hand sanitizer 
I feel sick with worry for him. He could die. Other medical staff have died in other countries. Some didn't have any underlying health conditions at all.
