Ferguson: R0 for Coronavirus is Probably 3.1

From the department of buried leads:

New data from the rest of Europe suggests that the outbreak is running faster than expected, said [Neil] Ferguson. As a result, epidemiologists have revised their estimate of the reproduction number (R0) of the virus. This measure of how many other people a carrier usually infects is now believed to be just over three, he said, up from 2.5. “That adds more evidence to support the more intensive social distancing measures,” he said.

Neil Ferguson is the guy in charge of the Imperial College study that predicted 2 million coronavirus deaths in the US and 500,000 in Britain if no control measures were taken. He now believes that Britain will keep its death toll under 20,000 due to the strong isolation and social distancing measures being taken.

Which is great! At the same time, estimating that R0 has increased from 2.5 to 3.1 is . . . very, very bad. It means that on average, every infected person infects three other people, not 2.5 other people—which makes the spread of the virus much wider and faster. Without any control measures, for example, it means that after ten generations a single person will be responsible for 120,000 infections instead of 15,000 infections.

In other words, control measures are even more important than we thought. This is really, really no time for Donald Trump to be screwing around with this stuff.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
