My parents are both in their 70's and in the shielded category due to chronic illnesses. DM badly broke her leg in a fall at home yesterday and has been operated on in hospital. My DF wants to look after her when she comes out of hospital, but I'm worried if DM gets infected in hospital then he might catch the virus - there have been a lot of covid deaths where she is being treated. He has a lung condition so he is particularly at risk.
Any ideas what we should do?
