Reinfections have been recorded from different strains because it's much easier to demonstrate that someone has been reinfected with a new strain. If someone has been reinfected with the same strain then it is hard to distinguish that from an infection that wasn't fully cleared originally. It doesn't necessarily mean that immunity is strain-specific.

People are really enjoying WFH and don't want it to end. It's important to keep the fear strong.

Meanwhile, I am baffled we didn't prioritize n95(or kn95) masks. Well... It's government, I'm not that baffled

A significantly more rational policy would have been to prioritize masks with filters and for the less than 1/12 of elderly people who live with younger generations, move them into a hotel room and pay for food delivery and care services.

All of this is cheaper and healthier than what was done.

1. Risk groups are not just old people, but also include a lot of people (e.g. asthmatics) that are a central part of the work force. Not all of these can WFH, they might be working in supermarkets, etc.

2. Some people don't even know they are at risk especially when they are young.

3. You can't fully isolate old people anyway. That's why we continue to see infections in hospitals, nursing homes, etc.

4. Even if you managed to isolate all risk groups, the spread of covid19 without any restrictive measures would be extremely rapid. While only a small fraction of the rest of the population would become severely ill, a tiny fraction of a large population can still be huge and might be enough to overwhelm hospitals.

If it were as easy as you suggested, surely it would have been tried - at least somewhere on the planet.

They did. Production is up 5x. But factories take time to build.

Entire new types of filters have actually been invented this year, going forward humanity is going to have a lot more choices when it comes to high quality filtering masks.
