A relative has had a cough for more than two weeks. Has had two negative COVID tests, taken 4 days apart. No temperature but has had pneumonia many years ago but otherwise fit and well. Not phoned Gp as it has been holidays and as they tell me there is a pandemic and people are busy. Is it ok to leave, or should I encourage them seeking help ( no doubt a triage phone call as nobody will want to see them with a cough).
I am not medical so no idea why a cough should just appear - their partner is well.
