How Did the World Miss Covid-19's Silent Spread? (nytimes.com) 265

Long-time Slashdot reader hankwang writes: The New York Times has an article on how the transmission of Covid-19 by seemingly healthy individuals was discovered in Germany on January 27, but the report was discredited because of a quibble over whether it was really asymptomatic or rather presymptomatic or oligosymptomatic transmission. Oligosymptomatic means that the symptoms are so mild that they are not recognized as symptoms... It took until March before asymptomatic transmission was publicly acknowledged as playing a significant role.
From the article. (Alternate source here): Dr. Rothe, an infectious disease specialist at Munich University Hospital, and her colleagues were among the first to warn the world [on January 30]. But even as evidence accumulated from other scientists, leading health officials expressed unwavering confidence that symptomless spreading was not important. In the days and weeks to come, politicians, public health officials and rival academics disparaged or ignored the Munich team. Some actively worked to undermine the warnings at a crucial moment, as the disease was spreading unnoticed...

It is now widely accepted that seemingly healthy people can spread the virus, though uncertainty remains over how much they have contributed to the pandemic. Though estimates vary, models using data from Hong Kong, Singapore and China suggest that 30 to 60 percent of spreading occurs when people have no symptoms... The Chinese health authorities had explicitly cautioned that patients were contagious before showing symptoms. A Japanese bus driver was infected while transporting seemingly healthy tourists from Wuhan. And by the middle of February, 355 people aboard the Diamond Princess cruise ship had tested positive. About a third of the infected passengers and staff had no symptoms...

[P]ublic health officials saw danger in promoting the risk of silent spreaders. If quarantining sick people and tracing their contacts could not reliably contain the disease, governments might abandon those efforts altogether... Plus, preventing silent spreading required aggressive, widespread testing that was then impossible for most countries. "It's not like we had some easy alternative," said Dr. Libman, the Canadian doctor. "The message was basically: 'If this is true, we're in trouble.'" European health officials say they were reluctant to acknowledge silent spreading because the evidence was trickling in and the consequences of a false alarm would have been severe...

As the research coalesced in March, European health officials were convinced. "OK, this is really a big issue," Dr. Agoritsa Baka, a senior European Union doctor, recalled thinking. "It plays a big role in the transmission..." Since then, the C.D.C., governments around the world and, finally, the World Health Organization have recommended that people wear masks in public.

    Science denial and saving face is widespread, this is the result.

          Well, when you're under explicit orders not to ask people about their attendance in the protests [nypost.com], it's not surprising you don't find infections from contacts at the protests.

            Before the protests even started evidence was mounting that outdoor transmission was far less common than indoors with poorly circulated air. Mask usage among protestors was significantly higher than the people who think crowding small indoor spaces is a good idea.
            That you far right people think that no spike linked to the protests means it's ok to go ahead and cram people shoulder to shoulder inside in a poorly ventilated space are because there was no rise in cases linked to areas with protests, well, in your case, just intellectually dishonest.

            The protests tend to be outside, and a lot of protesters are wearing masks and maintaining at least some social sistancing.

            I suspect there probably is some spreading among protesters, but those spikes wouldn't likely show up right away (given the incubation period and confusing the symptoms of covid for lingering effects of tear gas.

          • From the article:
            "there is no specific directive barring tracers from asking about protest participation"

            So where are you getting "explicit orders not to ask people about their attendance in the protests"?

        • The spike among younger demographics makes me think that this is unlikely. My read is that the lockdowns lasted too long, and made people stir crazy and irrational on risks when it ended. Lifting sooner and requiring masks might have made a bigger impact than the way it was done.

            Or lifting more gradually, actually requiring masks, and "leaders" setting a good example.

          Studies are showing that the raise is actually coming from bars and parties being held. Next, are people working in offices that have started up.
        • Any assertion protests are not spreading the disease needs to be accompanied by an explanation of how protestors have learned not to exhale when infected, not to inhale when uninfected, or spy-satellite photos of their secret vaccine production facilities.

          Obviously the dense crowds of tens of thousands of people are spreading it. I don't see the point of being purposefully obtuse about it. Deny physics and statistics if you want. It may (quite thankfully) be that there is lower transmission outdoors (or wit

          • Totally agree, facts before anything else.

            What I DO know is that masks are NOT for protecting YOU, outside a hospital environment, but they ARE effective at stopping YOU infecting others.

            So in relation to protests, as long as masks were worn (I don't have that info either) and hand sanitising was done, they shouldn't* be a big spreader.

      • Hmm, I see that mentioned in most stories I've see about the spike.

        Probably because the spike in new cases aren't in the same cities and counties where most of the protesting too place.

        I get it, science is hard. That's why we leave it to scientists, it prevents us from posting stupid shit on Slashdot.

    The events in Wuhan were well publicized in January. The explosion in the USA did not happen until March.

    The USA simply chose to ignore the available information.

    Other countries much closer to China like Taiwan or Australia took notice and have had virtually no cases.

    In the early days of the outbreak (late January), I managed to get into a meeting of microbiologists/community health professionals discussing Covid-19 transmission. The consensus was that transmission wasn't "airborne" because the virus was in droplets of liquid exhaled by people. I asked "isn't that airborne?" and got a lecture on the different types of transmission; droplets, aerisolized (Influenza A) or actual virus molecules being carried in the air ("airborne" which is how smallpox is transmitted).

    The message given by these professionals to the Ontario Ministry of Health was that the virus wasn't airborne (strictly true), which was interpreted as masks not being helpful (completely wrong). I don't think it was properly resolved here until late May.

    From what I saw, I can completely understand that scientists could get into an argument about what were the names of the actual states when the virus was passed between people and miss the point that seemingly healthy people can infect others.

    • Airborne transmission is very rare -- they were mostly correct. Most of the transmission is by being in close proximity to a symptomatic individual. Social distancing works best but scientists vastly over-estimated the median intelligence level of people --idiots turned out to be too stupid for that, so we've had to resort to masks which are a sub-optimal solution. Blocking symptomatic individuals from entering New Zealand along with one of the world's strictest social distancing enforcement appears to have

    In Thailand, they had 3-5 planes a day of people coming in directly from Wuhan well into the Chinese New Year. The only precautions that were made (around mid/late February) were taking temperatures at places of business and the airport... yet they magically dodged the bullet. There were a few cases of bus drivers or taxi drivers becoming infected, but in total they only had 3-4,000 infections.

    While I don’t take the official numbers as at all accurate (the cost of a COVID test up through early March was about USD$1,000), by all accounts they didn’t have much of a problem... despite a huge amount of tourists travelling throughout the country presumably spreading things. Masks were not widespread, especially in January and early February. Yet...

          The WHO's sole job is to aid and abet the spread of official government data from the whole world. They are also only advisory, the buck stops with the health organisation of every nation. Be that a nation in the middle of carnival which gets a lot of Chinese tourists, a nation that decides not to stop Las Fallas despite a known outbreak in Europe, a nation that ignores every other country while other countries go into knockdown, or a nation run by an orange toddler who takes out his ADHD on twitter.

        Well the WHO's comments were common knowledge, as was the fact that this was China's line. It's TFS that is revisionist. China claimed there was no person to person transmission right until the day before they shut down Wuhan.

        But you're right that what's going on in the USA is exclusively the fault of the USA.
