colleagues were becoming infected. all of us were definitely scared. ♪ ♪ >> narrator: although there were now hundreds of sick patients across wuhan, they weren't being logged in the cdc's much-touted reporting system. the official case count had in fact been revised down to 41. according to leaked documents from the city health commission and wuhan central hospital, local and provincial authorities were suppressing the numbers. they were only counting cases linked directly to the huanan market. and only they not the doctors were authorized to confirm cases. >> at the level of the hospital, we could not confirm a diagnosis. and i don't know what level could actually confirm the diagnosis. so to say there were 41 confirmed cases i don't think is incorrect.
but if you're talking about suspected cases, i guess that at that time, there were already hundreds and hundreds. ♪ ♪ >> narrator: during this period, the national health commission's scientists on e ground in wuhan were gathering extensive data about the outbreak, and preparing a paper on their findings. >> at the very beginning of january, the central government had dispatched a team of leading infectious disease experts from the peking university school of medicine-- it's kind of like the harvard medical school of china-- as well as from other leading universities. and so they arrived in wuhan, they began to look at the clinical data that they had gathered up to january 2. >> narrator: the data covered all 41 official cases hospitalized by january 2. ♪ ♪
it was an alarming picture. it turned out only two-thirdof cases were linked to the huanan market. the first case had no link to any of the others. therwere clusters of cases within families. the national health commission scientists concluded the virus could have acquired the ability for "efficient human-to-human transmission." and that there was potential for a pandemic. >> they had been working on this paper since early january, and so they would have submitted an internal version of the paper to a senior official in china. >> narrator: the chinese government did not answer our questions about whether anyone had signed off on the paper. but the scientists it had appointed ended up sending a draft to the prestigious "lancet" medical journal in london.
>> when i read through that paper, i had nothing but fear, because the severity of the disease was shocking. i mean, these patients, they were rapidly deteriorating into multi-organ failure, admission to intensive care unit, a high mortality. the virus was triggering this massive inflammatory explosion which was damaging the organs of their bodies, and when you see the severity of the illness combined with the signal of the risk of a global pandemic? fear. >> narrator: horton said he held off publishing the paper while it was getting peer-reviewed. in the meantime, beijing did not make public its team's findings-- including that the virus was likely being
transmitted from human to human. >> i think that what was happening was that very difficult interface between the message coming from the scientists, and the politicians who are trying to manage that message internally for domestic security and externally in terms of its international relations, and i think that's where the block took place. but i have no doubt that the scientists and doctors who were on the front lines knew exactly what they were dealing with. ♪ ♪ >> narrator: in beijing, the government secretly started to ramp up its response. xi jinping issued new instructions on the outbreak. they were passed down to the country's local and provincial health departments. ♪ ♪

the w.h.o. called its first press conference on the outbreak. >> so, good morning, colleagues, thank you for the opportunity to be here today with you. so just to provide a little bit of background about what coronaviruses are and... >> narrator: publicly, the w.h.o. had been sticking to the official chinese line that there was no clear evidence of human-to-human transmission. but in front of the media, the agency's coronavirus expert appeared to contradict that. >> so far, with the current virus, we have limited human-to-human transmission. but what we are preparing for is the possibility that there will be, there could be. that was my first press conference i've ever done. i presented the situation as i understood it, and as we understood it from the data, and as it relates to the guidance that we want to put out. and so when you have a respiratory pathogen, of course there would be human-to-human transmission, it's just, where is that happening and what is
the extent? >> narrator: news spread fast that the w.h.o. had confirmed human-to-human transmission. >> the first report came out from reuters. they sent out a news alert that the w.h.o. said that there was limited human-to-human transmission. so i quickly sent an email to geneva saying, like, "can you confirm this?", and started writing the story. you know, that the w.h.o. had identified this as a virus that can spread easily among humans. and then they said, "oh," they sent me an email to say, "oh, it was a misunderstanding. the preliminary investigations conducted by the authorities have found no clear evidence of human-to-human transmission. there has been no evidence of limited human-to-human transmission." >> narrator: in a statement, a w.h.o. spokesman told us they never intended to suggest that there was definitely human-to-human transmission happening.
despite the mounting evidence, the spokesman said w.h.o. scientists were not on the ground, so couldn't make that determination officially. >> we rely on the information that is provided to us. there's always more information that we need-- always. things were happening very, very quickly, um, and we were utilizing the information that we have, and we always go back to the countries to gather more information, and china was no different. >> i do appreciate that it's early on in the pandemic, and there was this, you know, there was what we call the fog of war. people are trying to understand what's happening, and you don't want to put out information before you don't really know what's happening. but it made a lot of us think, me included, that, you know, this wasn't such a big deal after all. so i just left it at that and scrapped the story.

decisions to hide the news so that the spring festival migration can proceed without any hiccups, without any panics. there's actually a very decent public health reason. if they had announced a lockdown, that would have meant that hundreds of millions of migrant workers would have been trapped in the major cities, which would have great implications for both public health, but also for stability. ♪ ♪ >> narrator: in wuhan, life continued as normal. there was a college careers event, performances, and a mass banquet attended by thousands. >> (speaking chinese): >> it was unnecessary. you know, the wuhan government could have canceled the banquet. the reporters talked to community workers, and they were afraid, and they tried to
convince district-level officials to cancel the banquet, but the district-level officials would not do it. they refused to do it. my guess is that the order to not do anything unusual came from the very top, you know, some very senior-level officials in beijing. >> narrator: on january 19, the head of the wuhan cdc was still reassuring the public. >> (speaking chinese): ♪ ♪ >> narrator: neither wuhan officials nor the chinese central government have specifically answered for why they were still downplaying the outbreak and allowing these mass gatherings and travel.
