COVID-19 Science Update for March 31st: Wear a Mask, Georgia’s SSE, Kinsa’s Fever Map

This article constitutes the March 31st, 2020 entry in the daily Quillette series COVID-19 UPDATES. Please report needed corrections or suggestions to jon@quillette.com. Today’s data According to statistics compiled by Our World in Data (OWD), the number of newly confirmed COVID-19 deaths increased yesterday. The data, as reported by the European Centre for Disease Prevention and Control (ECDC), indicated 3,698 new confirmed COVID-19 fatalities globally, up from Monday’s newly reported deaths, of which there were 3,125. This included 418 new cases in France, 128 in Germany, 28 in Canada, and 661 in the United States—all of which represent new highs for these countries. Italy and Spain recorded 810 and 812 new deaths respectively, roughly equivalent to their average daily values over the last week. As usual, the four countries that consistently registered the most new deaths over the last three weeks—France, Italy, Spain, and the United States—accounted for almost three-quarters of all new deaths worldwide (73 percent). One other statistical pattern worth noting: Yesterday’s drop in worldwide newly reported deaths—from 3,461 to 3,125—represented the second …

COVID-19 Science Update for March 30th: The Planet’s Deadly Viral Baseline

This article constitutes the March 30th, 2020 entry in the daily Quillette series COVID-19 UPDATES. Please report needed corrections or suggestions to jon@quillette.com. According to statistics compiled by Our World in Data (OWD), the number of newly confirmed COVID-19 deaths decreased yesterday. The data, as reported by the European Centre for Disease Prevention and Control (ECDC), indicated 3,128 new confirmed COVID-19 fatalities globally, down 10 percent from Sunday’s newly reported deaths, of which there were 3,461. This is only the second time in the last two weeks that the daily death rate has decreased. The rate of new deaths fell in France, the UK, Italy, Iran, and the United States. In Spain and Germany, the rate remained virtually unchanged. These seven countries have collectively accounted for over 80 percent of COVID-19 deaths in late March. So this is good news. While previous updates in this series have focused closely on short-term developments in the fight against COVID-19, today’s entry will examine some of the important background issues that are commonly referenced in public discussion about …

COVID-19 Science Update for March 29th: Keep Your Voice Down

This article constitutes the March 29th, 2020 entry in the daily Quillette series COVID-19 UPDATES. Please report needed corrections or suggestions to jon@quillette.com. According to statistics compiled by Our World in Data (OWD), the number of newly confirmed COVID-19 deaths increased yesterday. The data, as originally assembled by the European Centre for Disease Prevention and Control (ECDC), indicated 3,461 new confirmed COVID-19 fatalities globally, up slightly from Saturday’s newly reported deaths (3,318). As has been the case throughout mid- and late March, the new deaths were concentrated largely in Italy (887), Spain (832), the United States (411), and France (299). Taken together, these four countries accounted for about 70 percent of all newly reported global deaths—about average for the past three weeks. In the United States, about half of all cases are located in and around New York. As the New York Times reports, the city’s emergency-response services are becoming overwhelmed, and health care workers are beginning to be faced with the sort of live-or-die decisions that Italian doctors have been required to make. As discussed …

COVID-19 Science Update for March 28th: Bergamo’s Decimation, More SSEs, and the Case for Masks

This article constitutes the March 28th, 2020 entry in the daily Quillette series COVID-19 UPDATES. Please report needed corrections or suggestions to jon@quillette.com. According to statistics compiled by Our World in Data (OWD), the number of newly confirmed COVID-19 deaths increased yesterday. As reported by the European Centre for Disease Prevention and Control (ECDC) on Saturday morning, the data indicated 3,418 new confirmed COVID-19 fatalities globally. However, this figure embeds what I confirmed was an erroneous report for Argentina, artificially inflating deaths by 100. Correcting this would put the actual number of deaths at 3,318, which is still a substantial increase over Friday’s reported deaths, which were 2,684. As has been the case over the last three weeks, the highest number of dead were in France (299), Italy (971), Spain (769), and the United States (411), and these countries accounted for over 70 percent of total global deaths reported yesterday. This figure has remained above 65 percent for 18 of the last 19 days. The case of Italy is particularly alarming. Italy recorded its 1,000th …

COVID-19 Science Update for March 27th: Super-Spreaders and the Need for New Prediction Models

This article constitutes the March 27th, 2020 entry in the daily Quillette series COVID-19 UPDATES. Please report needed corrections or suggestions to jon@quillette.com.   According to statistics compiled by Our World in Data (OWD), the number of newly reported COVID-19 deaths increased yesterday. There were 2,681 new confirmed COVID-19 fatalities globally, compared to 2,423 reported on yesterday. This was largely due to increased death tallies in France (365 new deaths, up from 231 the day before), Italy (660, down from 685 reported on Thursday and 743 reported on Wednesday), Spain (655, down from 738), and the United States (246, virtually unchanged from Thursday’s report of 249, with the New York City area remaining the pandemic’s American epicenter). On Wednesday, I mentioned that just four countries—France, Italy, Spain, and the United States—represented 78 percent of that day’s newly reported global COVID-19 deaths. In yesterday’s reports, it was 79 percent. In today’s reports, it is 72 percent. This figure has remained above 65 percent for 17 of the last 18 days. In these four countries, the annualized …

COVID-19 Science Update for March 26th: Five Trends Shaping Medium-Term Policy

This article constitutes the March 26th, 2020 entry in the daily Quillette series COVID-19 UPDATES. Please report needed corrections to jon@quillette.com. Until today, these updates have begun with a rundown of the latest global data for COVID-19 published at Our World in Data (OWD). As of this writing on Thursday morning, however, the March 26th numbers have not yet been published at OWD. (However, for those interested, there do seem to be recent updates at the website of the European Centre for Disease Prevention and Control, whose reports have formed the statistical basis for OWD daily tallies since March 18th.) So I will skip the daily rundown of new numbers and proceed directly to the thematic focus of today’s update: a broad-stroke, point-form summary of some of the policies that, even at this early stage, seem likely to inform our global response to COVID-19. Until now, the focus was almost exclusively on the short-term response to the pandemic. But now that social and economic lockdowns in affected countries have somewhat dampened the exponential spread of …

COVID-19 Science Update for March 25th: Understanding Models

The latest global data for COVID-19—updated with reports received on March 25th, 2020—have been published at Our World in Data. Here are some of the numbers and trends that I believe deserve special attention, as well as a brief report on notable developments and analyses. Since March 21st, these updates have been published at Quillette in our section marked COVID-19 UPDATES. Please report needed corrections or suggestions to jon@quillette.com. The number of newly reported deaths increased yesterday. There were 2,200 new confirmed COVID-19 fatalities, compared to 1,764 reported on Tuesday, 1,660 on Monday, and 1,690 on Sunday. This was largely due to increased death tallies in France (240 new deaths, up from 186 the day before), Italy (743, up from, in reverse order, 601, 649, and 795), Spain (514, up from 462) and the United States (211, up from 119). The Netherlands had an unsettling jump to 63 new deaths (up from 34 on Tuesday). And some bad news in Sweden, which I discussed yesterday as being a European outlier due to its liberal approach …

(Italy also had its second straight day of decline in new cases reported: 4,789, down from 5,560 and 6,557 on Monday and Sunday respectively.) Spain’s daily tally jumped to 462, up from 394 on Monday. If these trends continue, …

COVID-19 Science Update for March 23rd: The Wealth Paradox

The latest global data for COVID-19—updated with reports received on March 23rd, 2020—have been published at Our World in Data. Here are some of the numbers and trends that I believe deserve special attention, as well as a brief report on notable regional developments and media analyses. Since March 21st, these updates have been published at Quillette in our section marked COVID-19 UPDATES. Please report needed corrections or suggestions to jon@quillette.com. Let me start off with some good news: For the first time in a week, the daily number of new global confirmed COVID-19 deaths has dropped—from 1,690 to 1,660. That’s a small drop, but it’s important. Since I began doing these updates informally on my Facebook page, there has always been at least one country, every day, that has reported a horrifying surge in daily death rates. (The last time that the daily death rate dropped was March 16th — 17th, and even that seemed to have resulted from the previous day’s anomalous doubling of global daily fatalities, fed by an order-of-magnitude increase in …

COVID-19 Science Update for March 22nd: Grim Omens in the U.S.

The latest global data for COVID-19—updated with reports received on March 22nd, 2020—have been published at Our World in Data. Here are some of the numbers and trends that I believe deserve special attention, as well as a brief report on notable regional developments and media analyses. Since March 21, these updates have been published at Quillette in our section marked COVID-19 UPDATES. Please report needed corrections or suggestions to jon@quillette.com. Yesterday’s global tally of total confirmed cases was 305,275. This represents a daily jump of 34,047, up from the previous daily jump of 28,891. This includes: Another 6.5K cases in Italy (a slight increase from the previous daily jump); A worrying 4.9K case jump in Spain (up from the previous daily jump, which was 2.8K); And a big 7.1K increase in the United States, the biggest U.S. jump to date. These three countries account for more than half of all new cases. If you add in France (1.8K) and Germany (3.3K), you get more than two thirds of global cases. There were 1,690 new deaths reported globally. …
