The symptoms of COVID are many and various. DH, DD and I returned from a weeks cruise, feeling slightly jaded, and put it down to staying up late on the last evening.
As none of us had any of the official symptoms for the illness, just felt a bit under the weather, we considered COVID and decided that it was unlikely to be that. We only tested when DD read on Facebook, that a number of people returning home from our cruise had tested positive for the illness. We tested and all three of us had, in fact, got COVID. None of us had a single symptom on the COVID list, merely felt a bit under the weather. DH and DD for a couple of days. Me, for over a fortnight.
