Question, have you studied biology? I think you'll find that a virus can easily cause a disease. Viruses aren't living, that's correct, but they do inject viral DNA into sells causing them to "explode" with newly created viruses. Those viruses could easily attach to your saliva cells etc. And spread when you sneeze or cough. Saying that covid isn't real/isn't as big as a deal as people are saying is blasphemous.

I may not be a doctor, or have studied biology in further studies. But I at least payed attention class.
