Ok, lemme debunk OP's fear mongering bullshit rq
The name of this virus isn't "coronavirus", it is being called that because that is the type of virus it is. And guess what? Coronaviruses aren't retroviruses. They replicate in a completely different manner.
A retrovirus is an RNA virus that contains a gene for a protein called "reverse transcriptase" to create a DNA copy of its RNA, which is then integrated into the host genome. Without reverse transcriptase, you don't have a retrovirus. Period.
And guess what this virus does not contain a gene for? Yeah, reverse transcriptase.
What would be the reason for treating it with anti-retrovirals if its a standard coronavirus?
Not positive, briefly looked into it and the retrovirals that have been working are NOT the ones associated with the retroviral characteristics I've spoken about here (reverse transcriptase and integrase, the defining proteins/genes of a retrovirus). The anti-retrovials targeting those have no effect, because this virus does not have those.
The one that is working is an anti-retroviral targetting a specific HIV protease, which is a protein that cleaves other proteins in a specific manner. It's likely that this coronavirus has a similar protease that plays an important function in it's replication, but more research is needed.
