China looks like its growth has flatlined, while the rest of the world is moving along an exponential curve. https://www.arcgis.com/apps/opsdashboard/index.html#/bda7594... Also, notice that 57k out of 81k have recovered.

China has only flatlined because extremely aggressive social distancing. I don't see that in the US occurring.

The US is blessed with low population density, and people don't share meals family style.

We don't have to copy everything China does, just do what has proven to work:

Fast testing and contact tracing.

I've been tracking the coronavirus news for the past few weeks and have found https://www.reddit.com/r/covid19 to be good for tracking the latest scientific/medical publications, and https://www.reddit.com/r/coronavirus for general news. For transmission rates, this team is updating their modeling results often: https://cmmid.github.io/topics/covid19/current-patterns-tran... On twitter, @datagraver is publishing some…

Both of those subs are incredibly tinfoily and panicky. Honestly reddit is the worst. And BI is right that they are doing the same as always, just consiparcy things https://www.businessinsider.com/coronavirus-reddit-social-pl... Also you might as well rename /r/Coronavirus/ to /r/politics2 aka fucktrump. It's the same thing over and over again

Edit: here’s a Lancet Editorial “COVID-19: too little, too late?” https://www.thelancet.com/journals/lancet/article/PIIS0140-6...

Seattle is about 2 weeks behind Lombardy. The Bay Area maybe 3 weeks behind. Everywhere in the US is going to be in that situation in 2 months at most, unless something very dramatic changes ASAP.

The kinds of measures being taken in the US are grossly inadequate for this challenge: leaders and some media outlets continue to downplay risks, residents continue to blithely go about their everyday lives, large gatherings like church meetings and sporting events continue as usual, the CDC/FDA is still blocking sufficient testing around the country, hospitals and medical workers are not being sufficiently trained and prepared, and the supply of personal protective gear and ICU beds is not going to suffice.

We have squandered 4–6 weeks of preparation for this crisis, and hundreds of thousands of people in the US may die as a result, with others experiencing permanent lung damage.

China has shown that this virus can be managed if the number of patients stays low enough that infections are discovered early and patients are treated aggressively with antivirals, supplemental oxygen as soon as blood oxygen starts to drop, mechanical ventilators for severe cases, etc. People’s immune systems generally do fight this virus off if we can keep them breathing for long enough. But that depends on having enough hospital capacity.

If everyone stays complacent and continues to mingle until there are hundreds of local deaths in each area it’s going to be a disaster.

Edit 2: To everyone here: If you have what seems like a minor cold, even if you are a young adult, please stay away from people and don’t spread it. What is 2 weeks of minor cough and sore throat for you might become severe pneumonia requiring hospitalization for your parent or neighbor or coworker. If anyone in the family gets a minor cold, please keep your kids out of school. Etc.

There are two extreme paths we can take. The first is that we do nothing, the other is that we completely lock down our society like China. While the first option would be unwise, the second would also be unwise. A complete shutdown for a disease as virulent as Covid-19 will just suppress the virus for the duration of the shutdown. Ignoring the extreme difficulty and impracticality of shutting society down for a mome…

Not limit testing? Approve the use of private testing facilities? Allow automated testing?

Those would all be good steps.

Why not get the news right from the primary source? The World Health Organization (part of the United Nations) publishes a daily situation report:

https://www.who.int/emergencies/diseases/novel-coronavirus-2...

Their director also has statements published regularly:

The kinds of measures being taken in the US are grossly inadequate for this challenge:…

I had an interesting experience - my local hospital (which is actually a very good medical hospital). Has already called in every at risk (which I am) person and had them do a check up (and in my case an x-ray).

They also have already stock piled masks and additional resources. The medical staff in the area are similarly mentally preparing, schools are prepping for the shutdown (at home school).

I wouldn’t say the US is doing nothing, this is rural Illinois. There just isn’t much to do here until it’s a problem. But as soon as we get a few test positives schools are planning shutdown (I’m assuming gyms will be used for patients as necessary).

If anyone wants to dig into the math, this is a non linear recurrence relation, with an external dependency, that is n_d+1 = f(a,n_d) n^(d+1)

bad news: How this behaves will depend a lot on a (containment measures etc...)

good news: If we can make a grow faster than an exponential, we can win

Agreed, Reddit is cancer. Reactionary hive mind internet at its worst. One of the biggest problems with Reddit is that Americans go on boards like /r/politics or in this case /r/Coronavirus, see extreme hostility towards America and Trump and assume that this hostility is all coming from Americans themselves, when really a substantial number of Reddit users (and users elsewhere on the Internet) are not American. Not…

Reddit is clearly just self-hating Americans, mostly kids. I guess you assume no American would spend so much time writing anti-Trump comments on r/politics?

I think the real issue is that you go to a place like r/politics or r/vancouver or r/bitcoin and think it's some canonical forum with some semblance of fairness but it's really just someone's little world with its own rules and agenda.

But you can't simply start your own subreddit because you're now r/vancouver2, r/TrueVancouver, or whatever and it can never get the same traction just because it's not the official-looking r/vancouver anymore.

Where it says next 2 months?

If the doubling time is one week there is just something like 100k - 200k infections in next two months.

I think those numbers are yearly infection estimates.
