After reading the following CDC web page I'm convinced all human coronaviruses are all engineered bio-weapons. Evolution is is nonsense, they engineered these critters to be adaptive human pathogens in the lab.
https://www.cdc.gov/coronavirus/types.htmlNotice they're calling it "coronavirus disease", as if you never recover from it...
You can not kill a virus as it is never alive to start with. Once the immune overpowers it, it keeps it under control. If stress or something distracts the immune system its possible the virus "escapes" and attacks anew. The immune system knows for example the Herpes virus is low risk so it breaks free easy.
Anti-biotic, aka against living organisms = death is effective against bacteria, fungus's and parasites because they are self reproducing organism, viruses are not.
As viruses can not reproduce and
need a host to make more of them, its a nonprolific (not producing offspring) existence.
