Maybe Chinese emigrants in Italy are young so they didn't notice the wave. But Taiwan/Hongkong/Macau? They are testing and tracing. When their recent travelers to Europe and America came back, a lot of them were infected and

How do you square that with the fact that there is no outbreak in any overseas Chinese community? Not Taiwan or Hongkong or Macau, nor in the epicenter of Italy ( https://www.reuters.com/article/us-health-coronavirus-ita

There could be a meaningful distinction between exposure and infection. I would define the first as anyone who was exposed to the virus (or even just parts of the virus) and generated antibodies. The second would be an actual infection and

There are two potential benefits of hcq people are hoping to prove: first as an antiviral, secondly as an immuno modulator for the IL-6 pathway. As a nonspecific antiviral any benefit tends to be for the early stage of the disease, possibly

Could I understand the effort this way? In general any Turing complete set of computational rules should be able to generate any computable expression and hopefully physics can be expressed with computable expressions (at least if it is at

It was known from early on that the arm for severe cases had trouble recruiting the target amount of patients. The study design clearly forbade patients who had received prior treatments with other antivirals. In the beginning when testing

High false negatives due to low viral load in samples would be problematic for diagnosis and treatment (except there is no specific treatment) but for public health purpose it is just as important to test for infectiousness. Imagine if we

I don't know where the "within half a kilometer" meme came from. Wuhan Institute of Virology is about 13.5km from the market by road or 30 minutes by car. And the two are separated by the Yangtze river: https://ich

People can draw their own conclusions. That is what is nice about solid evidence. I will make two notes: 1. Bats can transmit viruses to humans independent of wet markets and research activities and these villagers do travel to cities; 2. T

It is very unlikely COVID-19. Stanford did a study and showed that the prevalence was very low in the early period even if you had respiratory symptoms and common viruses had been ruled out: https://news.ycombinator.com/item

So for most of those who felt they already had the SARS-COV-2 in Jan or Feb it is very unlikely to be true. To quote: Prior to launching the clinical test, Pinsky and his colleagues tested samples collected from the back of the throat or lu

Testing people without symptoms would likely result in getting nothing given the limited sample size. The point is that the sampling was done with less bias, without the preconceived notion of who may actually have it (at least among fever

Because that is the definition of R0. Once people are aware and change their behavior R changes as well and is not readily translatable to a different setting.

Face shields are more effective than masks at preventing exchange of droplets.(1) They can be cleaned and reused so it may save money and material for the general public to popularize face shields. 1. "There may be some protection from

Why is that true? They are densely populated. Fewer people also means fewer resources: for example they couldn't supply themselves with masks.

What about other germs, esp from the doctors' own breath? Doctors in OR need sterile masks and hopefully they don't reuse in that setting. But outpatient clinics and testing sites, sure reuse is better than shutting them down due

The doctors are likely doing the intelligent thing, not necessarily hoarding. They should know that antivirals tend to work only at disease onset or as preventives. The production of these drugs can be ramped up very quickly so the amount t

I think the numbers are real. Shanghai is already taking Japan off high alert list and you can be sure they are very cautious. Since they monitor and even quarantine travellers they should have the data.
