Is anybody able to explain why there are so few new Corona cases in China? I mean, I know that the Wuhan area was locked down and that this way the outbreak was contained there. But China is far greater than Wuhan alone, and just like the virus was able to spread from Wuhan to the rest of the world, it must have spread to the rest of China as well. And during the recent month it must even have been spreading back from over the border into China.<p>How come that there are nevertheless only between 40 and 50 new cases per day?
There two comparisons to other diseases appear to contradict each other. First: COVID-19 is both less communicable and less fatal than SARS. Second: it has spread faster and killed more people than SARS. I would like to understand how both can be true.
The significant reduction in emissions worldwide is an opportunity to gather some interesting data that would have been difficult to estimate at other times. What other interesting science could be done now that might bring some positive from the pandemic?
I would like a bit more clarity on this chart [1] comparing R_0 and case fatality rate of COVID-19 with other similar diseases. I am trying to understand why Ebola did not kill as many people as COVID-19 has.<p>My understanding is that R_0 just depends somehow only on the virus itself, while there is another factor R = a R_0, which determines the actual reproduction number "in practice", taking into account isolation measures and such. So for Ebola R was much lower than R_0, so a lot fewer people died compared to COVID-19. Is this correct?<p>[1] <a href="https://media.nature.com/lw800/magazine-assets/d41586-020-00758-2/d41586-020-00758-2_17810952.png" rel="nofollow">https://media.nature.com/lw800/magazine-assets/d41586-020-00...</a>
On that coronavirus timeline it would be good to see:<p>* Wuhan throw a party to celebrate the lunar year<p>* Almost the entirety of China goes on holiday for the lunar year<p>* New Year holiday<p>* Border lock downs of various Countries within that timeline
I more worry about China get away with it. It have started SARS and now this. Both by eating wild animal. I do not believe it is biological weapon but more an accidental leak of virus during their research. But it is not that part that is lethal. But the part that there are so many wild animal market those virus can go and spread in stage 1. Then stage 2 punish everyone who said it and let it spread. The saying that it is not known is NOT true in China. The news were spread by doctors among themselves first in WuHan case and in SARS case one doctor bring it to HK and kill 300. And whilst the guy dare to say were punished, the systems (like wild market and no freedom of speech) continue. These two factors should be remember! Otherwise we will end up like twitter. They can use it to spread news (like American release the virus) even though they cannot even use twitter in China. If we forget and let them run WHO and PR war, ... good luck humanity.
