Why write about this now?
The information about the NTDTV source only existed as social media posts, and it seems important to preserve the memory of the event in a more stable format -- more details and links about this episode here:

Unfortunately, ProMED did not realize that the information actually came from Falun Gong's NTDTV, and amplified it.

When the The Free Press article was published, however, the news had already been clarified -- but Alina Chan, its author, ignored it, out of contempt for the WHO. ▫️6/7

NTDTV is a propaganda outlet linked to Falun Gong. They are not an honest actor, and are a frequent source of disinformation.
They may sometimes leak useful information from official sources, but anything coming from them must be taken with mega grains of salt. ▫️5/7

It was false, because as the WHO had already indicated, China had communicated on the outbreak several days before already.

It was also false, because Taiwan media were actually re-sharing content from NTDTV (it's their logo at the top right-hand corner). ▫️4/7

China Says This New Outbreak Is Nothing to Worry About. How Can We Be Sure?
Less than four years after Covid, as another respiratory illness spreads in China, we’ve learned nothing from the pandemic, writes Alina Chan.

Two weeks ago, Taiwanese media were the first to report an outbreak of pneumonia in several northern regions of China. Footage showed crowds of masked parents and children at a hospital in Beijing. Sick children attached to intravenous drips filled the lobby of another hospital in Liaoning as they waited hours to see a doctor.

Yet, for some people, neither China not the WHO were trustworthy -- were they hiding the beginning of a new pandemic? The Free Press published an accusatory article, falsely describing the outbreak as first reported by Taiwan media. ▫️3/7

In late 2023, an alert was sent on ProMED about outbreaks of respiratory diseases in China. Taiwan media had just reported on it. It seemed eerily familiar. The WHO quickly obtained and shared information from China. China had already communicated on the outbreak, a couple of weeks before! ▫️2/7

Do you remember the other pandemic that started in China in late 2023?
Probably not, and for a good reason: it did not happen.

The alarm was due to misinformation coming from a Falun Gong-linked outlet, laundered through other media. ▫️1/7 #covidorigin

Merci pour ces explications !

Le compte bsky[.]social redevient-il disponible après la migration, ou bien reste-il réservé ? Autrement dit, faut-il se soucier de possibles usurpations après la migration ?

Using data from Table1(*), here are the contributions of each discipline to bioRxiv over time.

Evolutionary biologists used to be leaders in preprint use, but were displaced, and now neuroscientists are by far the greatest contributers of preprints to bioRxiv

Major Chinese funder to stop paying fees for 30 pricey open-access journals Move comes amid effort to grow the country’s own journals

Are #openaccess fees that some journals charge authors too high? The Chinese Academy of Sciences, the world’s largest research institution, reportedly thinks so and plans to stop funding some, a move that could shake up #scientificpublishing. @science.org www.science.org/content/arti...

Dear Professor Birch,

A new kind of email I've been getting lately. I'm wondering: how long before my inbox is completely swamped by these?

Interesting how this scandal involves for real some false claims made about Covid origin:
- doing abroad with US funds research not allowed in the US
- skipping the evaluation process and having approval straight at the director office

As if false accusations were indeed admissions of intent

That said, I think it would be worth exploring the source of what seems to have been a disinformation campaign, with fake emails, fake quotes, shared by several outlets. ▫️6/6

When they were told the source was dodgy, their reaction was to ask the lab to prove its innocence: a classical inversion of the burden of proof. The same pattern happens with the origin of COVID-19. ▫️5/6

Yet, lab leakers fell for it and shared the claim on X.

No source nor explanation for how the email was obtained;
The whole email looked typed (even included a cursor!);
The purported sender had left the named organization in 2021;
The narrative in the article was inconsistent, mixing stories about a HIV vaccine and Marburg virus;
etc. ▫️3/6

In May 2025, a LondonPost article was shared by several lab leaker accounts on X. It claimed that the 2024 Marburg virus disease outbreak in Rwanda was a lab leak, and the screenshot of an email was provided as "evidence".

It was very easy to show that this was a complete fabrication: ▫️2/6

Yes. There have been many such stories from various places (incl. Oxford) for a long time. Also stories of buying illegal stuff to satisfy his demands.
