    BREAKING: More good news from case count in China, today number of new confirmed cases is less than two days ago. While more than yesterday, this is additional indication that actions are getting ahead of the outbreak and stopping the exponential growth. (see blue dots)

    Is there a group of concerned people organizing to do bottom-up precautionary / preparedness messages on social media that people actually listen to & share? E.G. above I tried more positive msg instead of fat tail risks

    Friends! Fill your freezer/pantry with tasties you'll eat anyways, 2-3 weeks of food. Saves $ buying in bulk. In rare case goes ⬆️, you'll help yourself and others. Got 25lb rice & 2 months butter, so I can share. Saved $40! And I'll probably just make lots of scones!

    Data on the number of contagions lags 3-9 days due to incubation & diagnostics. How many cases did we have 9 days ago? Orders of magnitude less. How many asymptomatic contagions do we have today? Orders of magnitude more. Keep voicing for masks wearing & quarantine enforcement

    Until we're more sure people are okay. Any self-isolating people, feel free to DM me for a delivery of cookies and takeout. Perhaps you would help me deliver to their door 🍪🍪📫

    We all owe these students who have voluntarily isolated themselves our thanks and respect. With transmission without symptoms (eg 4 german cases from 1 person from China ) more contacts/travelers should self-isolate, w/ us bringing cookies & great takeout

    Some sobering points from : 1. Early data systematically underestimates the danger of new bio threats, so 2. Proper containment measures are not taken until it is too late. This means that 3. The world will be unprepared for the eventual superbug 10x worse than Wuhan.

    a temporary sacrifice (stop travel, isolated care for potentially exposed) to avoid permanently nCov in humanity killing our grandparents, elderly friends, and our future selves, robbing us of retirement and playing with your grandkids?

    Src: As an individual person, we take life threatening risks all the time. It’s ok if we die. We will die. It’s not okay to take big risks for society. New virus in society with 4% death rate = permanent harm (and virus could mutate worse). Is it worth

    Dean of medicine is right. Outbreak bigger than cases we are sure of, b/c can’t test people fast enough & “infected but no symptoms” can spread it. Limit travel before we are sure it’s a big problem, b/c by time we are sure it’s too late to stop, b/c no symptom people spread it.

    I've seen a few tweets recently about how R_0 is the mean of a distribution (via ) and how its dispersion is important to understand (via & ). This is very true (for & otherwise), and it's why I posted this graphic last week. [THREAD] 1/x

    Article is right and new info shows outlook getting worse. Asymptomatic people typically spread for 10 days according to NYT article: -> temperature screening isn't enough, only precautionary quarantine / travel shut down. Be cautious, go get prepared

    When we warned on Ebola people said quarantine was impossible. At least in China urban scale quarantine is seen as an essential way to combat pandemics. We need effective policy -- and not wait for global catastrophe to teach us.

    Reducing travel is good. But much more effective to do research relevant and actionable for CC that has a much greater effect, and travel the same. Work on better problems. Frequent virtual conferences and other collaboration to increase effect and quality of research also good.
