I am starting to wonder more and more if a combo of “the virus burning out” and “voluntary mask compliance and group distancing” is actually working in Florida. That’s a promising positivity rate
Viruses "burning out" is not a scientific thing. If you're talking about how some viruses become milder over time, it takes a long time for that to happen and the driving mechanism is that the quick, severe, and deadly mutations destroy their hosts too quickly to stay in the population, which is not the case with COVID.
If you're talking herd immunity, we don't know what percentage of the population will need to be immune for herd immunity to be effective with regard to COVID. We're certainly no where near it since the lower estimates are 40% of the population (up to 75%).
CDC said yesterday that apparently immunity only lasts 3 months. Thoughts? To me, this implies that Covid will never end. Or either someone really wants to sell vaccines. My head hurts.
That's not what they said.
A person who has recovered from COVID-19 will likely be safe from reinfection for three months, according to updated guidance from the Centers for Disease Control and Prevention (CDC).
The information marks the first acknowledgement of a defined immunity period for people who have recovered from a COVID-19 infection.
Prior research has shown antibodies from recovered patients will fade over the course of a few months, but federal scientists had not previously said what that means for immunity.
The CDC previously recommended that someone recovered from a COVID-19 infection doesn't need to be tested again for three months so long as that person is asymptomatic, but made clear that any correlation to immunity was still unknown.
The CDC did not make a formal announcement of the findings; rather, the information was included as part of broader guidance about quarantining that was last updated earlier this month.
The science is still weak on this, that is why all the weasel words.
I just don't want people to go around saying how wrong the CDC was if this doesn't hold true. The CDC is making a best guess here at this time and making recommendations based on that best guess.

It’s similar to the flu. That’s why you need to get a flu shot every year.
See above. The CDC made no such comparison or got into details about mutations, which drive the ever-changing flu vaccines. And the flu vaccine lasts a long time... for the particular strain it was designed for.
