Just happened across this thread. I've been wondering, 'what is a virus'? Is it alive? It turns out that is an on-going subject of debate in the scientific community. Here is Part I of a not-too-dense article that sheds some light on these questions.

Part II is here:

So, 'maybe' . . . if you accept the proposition that viruses are inert particles (on their own), versus life forms, then maybe the language in talking about defeating/controlling/stopping them is more rightly 'de-activating' (or similar) . . . versus 'killing' them. Words matter, but in this case, I'm not smart enough to determine exactly how, . . . or, whether it matters much here in the case of stopping or eradicating COVID-19.
Interesting to read the 'why' about soap being so effective: . . .
"Some viruses also wear greasy overcoats, called envelopes, made from stolen shards of the membranes of the last cell they infected. Influenza and hepatitis C viruses have envelopes, as do coronaviruses, herpesviruses and HIV. Rhinoviruses, which are responsible for most common colds, and polioviruses don't. Here's a practical takeaway: Enveloped viruses particularly despise soap because it disrupts greasy membranes. Soap and water are to these viruses what exhaling garlic is to a vampire, which is why washing your hands works wonders."
