I probably did have Covid.
My brother who is an English teacher in China, visited my home in January 2020, even before the pandemic was widely covered by mainstream media.
I felt like I was breathing oil on a train, and passed out unconscious for a little while.
Got up and carried on my day, with a lot of struggle because I had no sick leave left at work, at the time.
I then gave up and had to go on sick regardless, and was in bed for a whole week, around the clock, 24-hours a day.
The most ill I have ever been in my life.
I haven't been ill since that (excluding my regular health issues), so I'm guessing I had it & have natural immunity now.
The cloth masks only give 10% protection on average from any microbes, including Covid.
I'm not prepared to wear N95 or FFP3: Grade 3.
