My wife has type 2 diabetes, chronic kidney disease a mild heart condition and a,weak chest.
She nearly died three times in 2018 and three times I have had the "does she want to be resuscitated" chat from the doctor each time accompanied by their advice that " we don't think it's a good idea".
On the last occasion she was down to the last choice antibiotic which luckily worked.
She has also had sepsis at least three times
Antibiotics of course will not work against a virus anyway and I have doubts whether her immune system will cope. She will also be more likely to pick up another bacterial infection if her immune system is compromised.
I have a mild heart condition so I am at some risk but nothing like her
The further away we can stay from anyone with the virus the better
