This makes the law narrowly focused and if you want a law to protect you from "known deadly virus" then make that law, and you'll cover HIV and any other known deadly virus.
Where is the law for hepatitis? etc... the list could go on and the point is that this law was only targeting HIV.
So sure, go write a new law and make sure it covers a broad set of things without singling out a specific group that is already marginalized.
We have all transmitted diseases. And "intentionally" gets pretty interesting -- how many times have we come in to work sick because we haven't enough sick days?
The magnitude of the effect of the disease is what is important. A cold? Well, it happens. HIV ... not so much.
Not only is HIV treatable nowadays, it's also not particularly easy to contract, especially if the person is on ARVs. Let's do a thought experiment. If you're the receptive parter in anal sex with a partner with a detectable viral load, what do you suppose the chances of contracting HIV are? 1 in 5? 1 in 20? 1 in 50?
It's 1 in 72 (1.38%).
What about if the insertive partner is undetectable? Same thought experiment. 1 in 100? 1 in 1000? Trick question: it's 0%.

Making it a felony to expose someone to a disease that is treatable and only has, at most, a 1.38% of even being contracted is just wrong headed, a carry-over from a time when we didn't know much about HIV and when we didn't have safe, effective treatments.
For reference: HIV/AIDS caused 4.7 deaths per 100K people with the virus in 2017.

Covid has caused 216.36 deaths per 100K of the total population in the US

Should anyone who breaks quarantine after testing positive be charged with a felony? Eh. Having a felony on your record is extremely serious.
Should someone be able to sue the person who infected them for all healthcare costs related to HIV going forward on the other hand? Absolutely.
It seems in the best case scenario of early detection and treatment, HIV will shorten your life by a decade or more, so the 4.7/100K death rate is highly suspect. If I understand that paragraph correctly, if you wait until symptoms appear, you're already in the 10-40 years life expectancy group - so another ~decade lost.
As for breaking quarantine - yes, a felony is extremely serious. But so is knowingly exposing others to a 1/200 chance of death (or whatever the current risk is). So I do think a felony is appropriate - but the felony is for (non-consensualy) exposing others. If one can break quarantine without doing so (by e.g. walking alone on the beach, or in the woods, when the quarantine order mandated staying at home), then the crime should be appropriately reduced, just as it would be for someone with HIV whose medication has rendered the risk of transmission negligible/zero.
I should also point out that quarantine is a much bigger imposition on personal liberty, than a duty to inform sexual partners of any STDs you carry.
