If you can take reasonable precautions that barely inconvenience you, but could easily prevent potentially fatal infections, what does it say about your morality that you choose not to?
It's a choice between doing small things that can easily benefit many more people than yourself, or deliberately choosing to risk others' health just "because".
Not to say it's a good thing to do, but that doesn't mean it reaches the level of "crime".

I didn't know that about the California law... but I understand that treatment is much more effective so I can see why it's no longer at a felony level.
How about those not wearing masks or at least maintaining minimum recommended behavior to minimize transmission get a 'reckless endangerment' and/or 'child endangerment' instead, not quite so Heavy Felony but still a solid signal to others that NOT helping to stop the spread of this is morally incorrect.
Edit: to more closely convey my understanding of the CA bill changes.
One instance of unprotected anal sex does not have the chance to infect 50+ others. Anal sex is a pretty clear situation where both parties can make the choice to take the risk if they want, and not hurt anyone else.
If I go outside without a mask and have COVID and breathe on something, that has a chance of infecting lots of people
Further... Everyone else at the mall can also choose to not take that risk, though it's not really true for students in high school.
There's that fallacy again. It won't die. It's not just the people in the mall. It's everyone THEY will infect, and the next generation of infections, and the next.
A pandemic like this (contra HIV, which is very uninfectious and is transmitted almost exclusively by consensual 1:1 activities) just plain isn't susceptible to moral reasoning at the level of individual actions. There is NO feasible way an individual can make an informed choice to "accept" risk of covid infection that doesn't also increase (significantly!) the risk borne by the rest of society.
You can't do it. Any moral statement of the form "this infection risk is OK because I/he/she/they are OK with it" is just wrong, logically.
You can't wave away all the mall-goers risk-taking with "they chose it", because you're not including all their siblings and roommates and parents who they'll necessarily infect who did NOT choose that. You need to come up with another definition for "choice" than the one we conventionally understand.
Again, you're using language of individual risk. That doesn't work here.
For the mall example... That other person, who chose to come there and be exposed? The one with roommates, and a grandmother living next door? It's not me - living alone, in this scenario - who chooses to expose them. It's the one who lives with them, if anyone. You're taking their responsibility and piling it on to me - but there's a lot of links in the causal chain before the harm comes to pass, and some of those links bear far more responsibility. It's like blaming the guy who goes to the bar after a long day for the actions of another guy who goes to the same bar and kills a family drunk driving home, because by being there he contributed to an atmosphere of heavy drinking.
The language of individual risk and responsibility isn't quite so limited in my mind as it is in yours.
