Infections are still high, but the LA/CA case-fatality rate has dropped since spring. Partly we’re spotting more of the mild cases, and younger people are a bigger percentage of cases now.

But also we’ve learned more about how to treat it:

• dexamethasone for patients on oxygen
• remdesivir shortens recovery time
• nasal oxygen turns out to be enough for many patients who would’ve been intubated
• we know about the clotting so we can jump on anti-coagulants

(Note that a certain high-profile Twitter user’s favorite covid drug treatment isn’t on that list because it doesn’t actually work on covid.)
