Here we go again

I got infected with covid for 2nd time. It was unavoidable as we have a couple , who are staying in our elderly resthouse ,and got infected with covid.In the weekend and days before i entered many times a day their room. We had taken the safety precautions , but they never vent their room and the husband was coughing all the time. So the room was full of corona aerosols. Luckily symptoms are mild. Just cough and tired but it will cure. I am homebound again for a bout 7 days.
