Lessons From Wuhan

The Case for Lockdowns in New York City, Seattle and Other Major Cities in the Future

(Extracted From An Analysis By Tomas Pueyo)

On January 21st, the number of new diagnosed cases in Wuhan begins to explode: there were around 100 new cases. In reality, there were 1,500 new cases that day, growing exponentially. But the authorities didn’t know that. What they knew was that suddenly there were 100 new cases of this new illness.

Two days later, authorities shut down Wuhan. At that point, the number of diagnosed daily new cases was ~400. Note that number: they made a decision to close the city with just 400 new cases in a day. In reality, there were 2,500 new cases that day, but they didn’t know that.

The day after, another 15 cities in Hubei shut down.

Up until Jan 23rd, when Wuhan closes, the virus is growing exponentially. True cases were exploding. As soon as Wuhan shuts down, cases slow down. On Jan 24th, when another 15 cities shut down, the number of true cases grinds to a halt. Two days later, the maximum number of true cases was reached, and it has gone down ever since.
