Most places are seeing increasing rates of infection, even in spite of extreme measures. I'm not suggesting it's magic, just that it's more infectious than a common cold, which is pretty hard to avoid in winter where I live at least.

I agree that could be worded better (I'll leave it up since you've replied), but I meant it's hard to avoid if you're going shopping every few days - people are not good at infection control and many are pretty much asymptomatic for a long period. Lockdowns are controlling the rate of spread, not stopping it, despite best efforts, and will I suspect be released after a few months for that reason - because it has infected > 50% anyway and those people are allowed out after testing.

Unfortunately, it's really, really hard to say anything concrete about the transmission rate. Testing is different everywhere, and usually far too limited, and we know there are a lot of asymptomatic cases. But, if we accept some big caveats, it certainly looks like the transmission rates in locked down regions are dramatically reduced. People are still going to the store, ordering food delivery, going for walks and jogs, etc. A big chunk of people are actually still going to work everyday for essential services. But nonetheless, transmission appears to be way down, even in Italy, which had one of the worst starts of any country.

Yes sure, probably we won't know much concrete till well after this is past.

I'm encouraged by the progress in Italy, but don't see how you can avoid having most of the population catch this in the long term without a vaccine. It appears to be very hard to control even with really draconian quarantines which only have an impact after weeks and cannot realistically hold for more than a a few months, esp in poorer countries. I'm not saying don't quarantine, it's essential to avoid really horrific deaths, just that it may not stop the majority getting it in within a year or so.

If it mutates of course that's another problem but this disease is so virulent and the economic damage of effective countermeasures is so disastrous that I cannot believe the world will not prioritise mass vaccinations when that arrives and eliminate it whatever the cost.
