AP here is only reporting that there is a US government document saying as much. Which was conveniently leaked to them.<p>Reading between the lines, this document seems to include a statistical analysis of Chinese trade patterns to conclude that its trade in medical supplies in January deviated from the past.<p>The idea that China was buying more medical supplies in January seems entirely obvious to me, and I’m pretty sure I have seen previous reports of this, extending even beyond January.<p>The Wuhan Lockdown happened on January 23rd. Do I believe that they were importing more medical equipment in the month where they locked down an entire providence due to the emergence of a new and deadly contagious disease? Yes. Does it take advanced statistics and p-values do convince me of that fact? No.<p>But, of course, including a bit of stats in such a paper might also induce people to put more stock into its other claims, namely that buying such materials was a motivating factor to hide the extend of the disease. Or that China was hiding the extend of the disease in the first place.<p>Here's the WHO's bulletin on the matter. This is based on information they were given by China <i>in December</i>. If you search any news, you'll also find reference to China briefing their US contacts on January 3rd, with similar information. The bulletin itself is from <i>January 5th</i>: <a href="https://www.who.int/csr/don/05-january-2020-pneumonia-of-unkown-cause-china/en/" rel="nofollow">https://www.who.int/csr/don/05-january-2020-pneumonia-of-unk...</a><p>Quotes:<p><i>On 31 December 2019, the WHO China Country Office was informed of cases of pneumonia of unknown etiology (unknown cause) detected in Wuhan City</i><p><i>Of the 44 cases reported, 11 are severely ill, while the remaining 33 patients are in stable condition.</i><p><i>National authorities report that all patients are isolated and receiving treatment in Wuhan medical institutions.</i><p><i>One hundred and twenty-one close contacts have been identified and are under medical observation;</i><p>So they were hiding it, except they told WHO that they had severely ill patients which had been isolated? And that they were tracking >100 people that had been in contact with these patients, indicating the believe that the disease may be contagious?
