Don’t read too well? The person I was replying to said all viruses get weaker and disappear. I provided an example of one virus (and later several others) that did not get weaker or disappear. I didn’t say SARS-CoV-2 was similar to smallpox or polio in structure, or spread, or fatality rate, or anything else. I said not all viruses get weaker on their own and disappear.
Do you disagree with me that not all viruses get weaker and disappear on their own? Or do you agree with me that some viruses remain dangerous and present over time?
I read just fine. You have a problem. Go see someone about it.
