My husband came back from a trip to Melbourne with Covid! I kissed him passionately when he jumped off the plane, and the next day he felt terrible and tested positive on a RAT and PCR test! He isolated, but I continued to kiss him, sleep next to him and engage in ummm….other activities with him (it was short lived symptoms). I RAT tested most days and was negative. On his 6th day I did a PCR for me and the kids and we all came back negative. On the same day he did another RAT and was still positive, so the virus had not left his body yet but I still didn’t get it. I clearly couldn’t get Covid if I tried!
