Probably not worded the title very well to be honest! Person who works in a healthcare setting, so could be coming into contact with the virus quite a bit, was ill just over a month ago but has now recovered and had a negative test through work since. They’ll probably have some immunity, but, if they come back in contact with a positive case, can they then still carry the virus and pass it on to other people? Presuming clothes are changed and hands washed etc in between seeing people. Any ideas?
