Love this ❤ 9.2K🔁 1.6K Photo ❤ 2.9K🔁 782 I’ve been trying my best to stick to science and not politics but as a public health professional and an American it makes me ill to see @POTUS cutting funding to @WHO at any time but especially in a pandemic ❤ 2.9K🔁 884 It is a fundamental scientific error to take the current success of containment in some places as a sign that permanent containment is possible.

Like a forest fire, intense control in one place fails if there are sparks from other places. We must strengthen the weak links. But test reagents, … ❤ 3.2K🔁 691 But here's why it is a best-case, likely unattainable scenario. 1) We have not proven that US-style social distancing can produce R_effective<1 (declining case numbers). On this I'm hopeful, but it's a hope not a fact. ❤ 2.5K🔁 427 If at the same time we ramp up testing capacity and the ability to trace contacts, in a very best-case scenario, we might conceivably be able to turn to a Korea- or Singapore-style mix of less intense distancing combined with super-intense… ❤ 2.9K🔁 464 If our social distancing works it is possible we will not just flatten the curve, but get a decline in cases. Under a best-case scenario, we will keep that policy in place long enough to get down to very, very few cases domestically. ❤ 2.7K🔁 385
