The team dug deep into data to figure out when the outbreak started spreading in earnest: Conclusion is December 2019.
They spent a lot of time on data from the Huanan market, finding that people w/Covid had visited the same stalls where positive samples were found.
They also went to the Wuhan Institute of Virology & asked a ton of questions. The list of rumors they confronted there are listed in the Appendix. eg
Still, this was a government sanctioned visit. While @MMKavanagh doesn't have reason to believe SARS2 came from a lab, he told me: "This is an authoritarian regime that closely holds information. The WHO has gotten a remarkably good look at some data but it can only get so far."
.@edwardcholmes told me it's (a) naive to think that a 2-wk visit to China will reveal the origin & (b) naive to think that any investigation they did would satisfy those saying this is a lab-leak.
"Bloody hell, this will go on for years." (A darling quote cut from my story)
Most remarkably, @DrTedros@WHO isn't completely satisfied with the origin investigation. "In my discussions with the team, they expressed the difficulties they encountered in accessing raw data...I do not believe that this assessment [into Wuhan Institute] was extensive enough."
This is NOT the final investigation. Far from it. More on this & other findings in my piece, which is wayyy shorter than the report. Please read it :) nature.com/articles/d4158…

So many stories on reaching vaccine herd immunity! But there's a massive dilemma. Here's a 🧵on what I mean...
About 50 countries have fewer than one nurse per 1000 people. Israel has 6x that rate. UK has 10x. US has 15x. Belgium has 20x. Guess which countries want it all?
Have you seen what 1 nurse/1000 looks like?
Picture people hurt in car accidents who die by the road when wounds could have been stemmed; women dying in childbirth; untreated diabetes; children dying from infected wounds, burns, stomachs. A lack of healthcare is palpable.
What do most countries few nurses have in common?
Many are former colonies, where colonizers subsidized just enough medical care to ensure that people were healthy enough for labor, but they didn't invest in national health systems. Slave traders did less.
There's a persistent myth that pathogens become less deadly over time.
@rkhamsi & @dylanhmorris just reminded me of this since people are apparently acting assured that SARS2 can't become more deadly? Psh.
Short 🧵of history beginning w/hopes of an end to infectious disease
According to Frank Snowden's "Epidemics & Society", 'eradicationists' of the 60s & 70s foretold the end of infectious disease. We had some cures, and they said the bugs become less deadly over time. But like evolutionary psychologists(dis!), they didn't study evolutionary biology
If they had, they'd realize that evolution doesn't have directionality. Anyways, time proved them wrong. eg New strains of dengue evolved, and a second infection with a new strain can be deadly. The HIV epidemic showed that unknown viruses emerge from nature fairly regularly.
Azar just released a delusional, alternative history of Covid testing in the US. I’m mad because our testing failures allowed this outbreak to blow-up. We can’t fix our system if we ignore where it is broken. I suspect @PublicHealth agrees.
“It is indisputable that the United States has built the most extensive testing system and strategy of any major country,” says Azar.
False. Several countries have had percent positivity ~1% whereas US has never been below 5% and is >10% today. Refs KCDC & USA @JohnsHopkins
"The federal government got out of the way of test development in safe and sensible ways,” says Azar.
False. In Feb, CDC & FDA blocked labs from testing as the disease spread exponentially. I broke this story👇🏼& wrote more like it as the year wore on. nature.com/articles/d4158…
First 20 min of this delusional evaluation of the Trump Admin's response to Covid is all about blaming China, with some vitriol for WHO. "If a novel virus like this emerged in a Democratic nation, this epidemic would have never happened," says Azar.
As Covid spread in March, Azar says the government acted swiftly to control spread (they definitely did not). He says the key driver of the pandemic -- ready for it -- was thousands of Chinese workers flying to Italy.
Azar says it's a myth to say that if we had a better testing and surveillance system we could have curbed the virus in February.
(Why is this session even called 'lessons learned'?)
In contrast to the US, many low income countries were scaling up tests, building isolation centers, & enforcing quarantines BEFORE THEY EVEN HAD A HANDFUL OF CASES.
They don't have the luxury of relying on hospitals to care for floods of patients. nature.com/articles/d4158…
In 1995, Congolese Ebola discoverer @MTamfum treated Ebola patients with blood from survivors, despite being told not to by the CDC & WHO. 7 of 8 survived. nature.com/articles/d4158…
The NIH failed to replicate his findings in monkeys, but @MTamfum, "Professor Muyembe", didn't give up. “There should be a truth in here,” Muyembe told me.
He hired one of the survivors in his lab & convinced him to fly to the NIH in 2006, along with his sister & a grad student.
At the NIH, the student & other researchers isolated the survivors' antibodies. These antibodies became the basis for an experimental drug, mAB114, that @MTamfum pushed to test in the 2019 outbreak. It was HARD to conduct this trial. nature.com/articles/d4158…
