The Bearer of Good Coronavirus News

Howard Laitin.  Dr. Ioannidis argues[ The Bearer of Good Coronavirus News, Allysia Finley ,Wall Street Journal  4-24-20] that Covid-19 is far less deadly than modelers are  assuming.  Dr. Ioannidis estimated that the U.S. fatality rate could be as low as 0.025% to 0.625% and put the upper bound at 0.05% to 1%—comparable to that of seasonal flu.

“If that is the true rate,” he wrote, “locking down the world with potentially tremendous social and financial consequences may be totally irrational. It’s like an elephant being attacked by a house cat. Frustrated and trying to avoid the cat, the elephant accidentally jumps off a cliff and dies.”

A substantial proportion of those dying with Covid-19 had one or more other serious underlying complications. Prof. Neil Ferguson, when discussing his sharply  downward revised estimates for English deaths,  stated that most of these  people would have died from other underlying causes within several months, had they not, at that time,  succumbed to the coronavirus<

However, NVSS’ recently revised  cause of death  reporting directive [https://www.cdc.gov/nchs/data/nvss/vsrg/vsrg03-508.pdf ] plus Medicare’s  financial incentivization by paying   hospitals and treating physicians more when they report their patient as as suffering from covid-19  infection  have  made “Covid-19  associated deaths” the prime recording category and therefore “Covid-19  associated deaths” now shows up as ” the leading cause of death in the United States.”

The current CDC dominated federal draft guidelines threshold values for opening up the economy as they apply to Torrance  translate into the following: (Using  145,000  as Torrance’s  population)n   if Torrance exceeded either four  identified cases per month OR  exceeds one hospitalization per month Torrance  would be below the threshold  that would allow the reopening of the Torrance economy.[ Also given the expected increase in testing,  it is nearly  certain that more cases will be discovered  and  that  Torrance  will never be able to achieve the threshold  value that would allow the reopening of the Torrance economy.]

Defenders of coronavirus lockdown mandates keep talking about science. “We are going to do the right thing, not judge by politics, not judge by protests, but by science,” California’s Gov. Gavin Newsom said this week. Michigan Gov. Gretchen Whitmer defended an order that, among other things, banned the sale of paint and vegetable seeds but not liquor or lottery tickets. “Each action has been informed by the best science and epidemiology counsel there is,” she wrote in an op-ed.

But scientists are almost never unanimous, and many appeals to “science” are transparently political or ideological. Consider the story of John Ioannidis, a professor at Stanford’s School of Medicine. His expertise is wide-ranging—he juggles appointments in statistics, biomedical data, prevention research and health research and policy. Google Scholar ranks him among the world’s 100 most-cited scientists. He has published more than 1,000 papers, many of them meta-analyses—reviews of other studies. Yet he’s now found himself pilloried because he dissents from the theories behind the lockdowns—because he’s looked at the data and found good news.

In a March article for Stat News, Dr. Ioannidis argued that Covid-19 is far less deadly than modelers were assuming. He considered the experience of the Diamond Princess cruise ship, which was quarantined Feb. 4 in Japan. Nine of 700 infected passengers and crew died. Based on the demographics of the ship’s population, Dr. Ioannidis estimated that the U.S. fatality rate could be as low as 0.025% to 0.625% and put the upper bound at 0.05% to 1%—comparable to that of seasonal flu.

“If that is the true rate,” he wrote, “locking down the world with potentially tremendous social and financial consequences may be totally irrational. It’s like an elephant being attacked by a house cat. Frustrated and trying to avoid the cat, the elephant accidentally jumps off a cliff and dies.”

Dr. Ioannidis, 54, likes metaphors. A New York native who grew up in Athens, he also teaches comparative literature and has published seven literary works—poetry and fiction, the latest being an epistolary novel—in Greek. In his spare time, he likes to fence, swim, hike and play basketball.

Early in his career, he realized that “the common denominator for everything that I was doing was that I was very interested in the methods—not necessarily the results but how exactly you do that, how exactly you try to avoid bias, how you avoid error.” When he began examining studies, he discovered that few headline-grabbing findings could be replicated, and many were later contradicted by new evidence.

Scientific studies are often infected by biases. “Several years ago, along with one of my colleagues, we had mapped 235 biases across science. And maybe the biggest cluster is biases that are trying to generate significant, spectacular, fascinating, extraordinary results,” he says. “Early results tend to be inflated. Claims for significance tend to be exaggerated.”

An example is a 2012 meta-analysis on nutritional research, in which he randomly selected 50 common cooking ingredients, such as sugar, flour and milk. Eighty percent of them had been studied for links to cancer, and 72% of the studies linked an ingredient to a higher or lower risk. Yet three-quarters of the findings were weak or statistically insignificant.

Dr. Ioannidis calls the coronavirus pandemic “the perfect storm of that quest for very urgent, spectacular, exciting, apocalyptic results. And as you see, apparently our early estimates seem to have been tremendously exaggerated in many fronts.”

Chief among them was a study by modelers at Imperial College London, which predicted more than 2.2 million coronavirus deaths in the U.S. absent “any control measures or spontaneous changes in individual behaviour.” The study was published March 16—the same day the Trump administration released its “15 Days to Slow the Spread” initiative, which included strict social-distancing guidelines.

Dr. Ioannidis says the Imperial projection now appears to be a gross overestimate. “They used inputs that were completely off in some of their calculation,” he says. “If data are limited or flawed, their errors are being propagated through the model. . . . So if you have a small error, and you exponentiate that error, the magnitude of the final error in the prediction or whatever can be astronomical.”

“I love models,” he adds. “I do a lot of mathematical modeling myself. But I think we need to recognize that they’re very, very low in terms of how much weight we can place on them and how much we can trust them. . . . They can give you a very first kind of mathematical justification to a gut feeling, but beyond that point, depending on models for evidence, I think it’s a very bad recipe.”

Modelers sometimes refuse to disclose their assumptions or data, so their errors go undetected. Los Angeles County predicted last week that 95.6% of its population would be infected by August if social distancing orders were relaxed. (Confirmed cases were 0.17% of the population as of Thursday.) But the basis for this projection is unclear. “At a minimum, we need openness and transparency in order to be able to say anything,” Dr. Ioannidis says.

Most important, “what we need is data. We need real data. We need data on how many people are infected so far, how many people are actively infected, what is really the death rate, how many beds do we have to spare, how has this changed.”

That will require more testing. Dr. Ioannidis and colleagues at Stanford last week published a study on the prevalence of coronavirus antibodies in Santa Clara County. Based on blood tests of 3,300 volunteers in the county—which includes San Jose, California’s third-largest city—during the first week of April, they estimated that between 2.49% and 4.16% of the county population had been infected. That’s 50 to 85 times the number of confirmed cases and implies a fatality rate between 0.12% and 0.2%, consistent with that of the Diamond Princess.

The study immediately came under attack. Some statisticians questioned its methods. Critics noted the study sample was not randomly selected, and white women under 64 were disproportionately represented. The Stanford team adjusted for the sampling bias by weighting the results by sex, race and ZIP Code, but the study acknowledges that “other biases, such as bias favoring individuals in good health capable of attending our testing sites, or bias favoring those with prior Covid-like illnesses seeking antibody confirmation are also possible. The overall effect of such biases is hard to ascertain.”

Dr. Ioannidis admits his study isn’t “bulletproof” and says he welcomes scrutiny. But he’s confident the findings will hold up, and he says antibody studies from around the world will yield more data. A study published this week by the University of Southern California and the Los Angeles County Department of Public Health estimated that the virus is 28 to 55 times as prevalent in that county as confirmed cases are. A New York study released Thursday estimated that 13.9% of the state and 21.2% of the city had been infected, more than 10 times the confirmed cases.

Yet most criticism of the Stanford study has been aimed at defending the lockdown mandates against the implication that they’re an overreaction. “There’s some sort of mob mentality here operating that they just insist that this has to be the end of the world, and it has to be that the sky is falling. It’s attacking studies with data based on speculation and science fiction,” he says. “But dismissing real data in favor of mathematical speculation is mind-boggling.”

In part he blames the media: “We have some evidence that bad news, negative news [stories], are more attractive than positive news—they lead to more clicks, they lead to people being more engaged. And of course we know that fake news travels faster than true news. So in the current environment, unfortunately, we have generated a very heavily panic-driven, horror-driven, death-reality-show type of situation.”

The news is filled with stories of healthy young people who die of coronavirus. But Dr. Ioannidis recently published a paper with his wife, Despina Contopoulos-Ioannidis, an infectious-disease specialist at Stanford, that showed this to be a classic man-bites-dog story. The couple found that people under 65 without underlying conditions accounted for only 0.7% of coronavirus deaths in Italy and 1.8% in New York City.

“Compared to almost any other cause of disease that I can think of, it’s really sparing young people. I’m not saying that the lives of 80-year-olds do not have value—they do,” he says. “But there’s far, far, far more . . . young people who commit suicide.” If the panic and attendant disruption continue, he says, “we will see many young people committing suicide . . . just because we are spreading horror stories with Covid-19. There’s far, far more young people who get cancer and will not be treated, because again, they will not go to the hospital to get treated because of Covid-19. There’s far, far more people whose mental health will collapse.”

He argues that public officials need to weigh these factors when making public-health decisions, and more hard data from antibody and other studies will help. “I think that we should just take everything that we know, put it on the table, and try to see, OK, what’s the next step, and see what happens when we take the next step. I think this sort of data-driven feedback will be the best. So you start opening, you start opening your schools. You can see what happens,” he says. “We need to be open minded, we need to just be calm, allow for some error, it’s unavoidable. We started knowing nothing. We know a lot now, but we still don’t know everything.”

He cautions against drawing broad conclusions about the efficacy of lockdowns based on national infection and fatality rates. “It’s not that we have randomized 10 countries to go into lockdown and another 10 countries to remain relatively open and see what happens, and do that randomly. Different prime ministers, different presidents, different task forces make decisions, they implement them in different sequences, at different times, in different phases of the epidemic. And then people start looking at this data and they say, ‘Oh look at that, this place did very well. Why? Oh, because of this measure.’ This is completely, completely opinion-based.”

People are making “big statements about ‘lockdowns save the world.’ I think that they’re immature. They’re tremendously immature. They may have worked in some cases, they may have had no effect in others, and they may have been damaging still in others.”

Most disagreements among scientists, he notes, reflect differences in perspective, not facts. Some find the Stanford study worrisome because it suggests the virus is more easily transmitted, while others are hopeful because it suggests the virus is far less lethal. “It’s basically an issue of whether you’re an optimist or a pessimist. Even scientists can be optimists and pessimists. Probably usually I’m a pessimist, but in this case, I’m probably an optimist.”

  1. Dr. Ioniddes is a voice of sanity and reason in an ages of madness. Would that there were more like him in the medical profession, and even more in the medical bureaucracy.

  2. It is interesting that Governor Cuomo of New York’s calculation of the percentage of deaths from coronavirus in out of the total number of people infected with the virus is 0.5 percent–which is well within the range suggested by Dr. Ionnides last month. This gives him a lot of validation.

    Cuomo based his estimate on a random sample of people tested for the virus in many areas of the state by the state health department. That survey showed that 13.9 per cent of all New York State residents and 21% of New York City residents had antibodies in their system for the disease–meaning that their bodies had already fought it off. Most of these individuals either had no symptoms or very mild ones. Enough to create “herd immunity?” I would like to knoow what the experts on this phenomena think.

  3. China, the media and the W DC kleptocrats created a big economic disaster to prevent a small man-made disaster!

  4. @ Bear Klein:
    HI, Bear

    I have been closely following the Worldometers. The virus is clearly past its peak of daily increases, as summer approaches. Apparently, heat and humidity are lethal to its spread. This is confirmed, by the continuing lack of major spread in tropical countries. Also good news: The Southern Hemisphere, which entered autumn in March, did not experience any sort of “spike” in cases — even though Australia and New Zealand have been thoroughly infected by now. That points to a very manageable autumn in the Northern Hemisphere this year as well.

    I’m getting disgusted with Shmuel/Adam and Reader’s shenanigans, which Ted has not helped in posting ridiculous pseudo-scientific articles about “death rates”. You have the correct take on this: When someone dies, he becomes a very real “one” death, regardless of how the statisticians mix and max useless ratios like “death rates”.

  5. Bear, I’m fairly certain I replied to your post. My reply got put into moderation, then “disappeared” (Chinese-style?)

  6. @ Michael S:
    I hope you are correct about the virus having peaked. On the 25th this occurred:

    6201 new cases and 375 new deaths in Brazil

    35419 new cases and 2065 new deaths in the United States

  7. @ Bear Klein:
    Bear, I don’t know what is happening in Brazil. Here’s what I got from Wikipedia:

    PROVINCE CASES DEATHS DEATHS/MIL POP.

    Amazonas 3,635 287 69.25 4,144,597
    Pernambuco 4,507 381 39.87 9,557,071
    Rio de Janeiro 6,828 615 35.62 17,264,943
    Ceara 5,421 310 33.95 9,132,078
    Sao Paulo 20,004 1,667 36.30 45,919,049

    Something strange is clearly happening in Amazonas. Despite its isolation on the upper Amazon, the capital of Manaus is a seaport with possibly much connection with China. The cases in Sao Paulo and Rio are obviously connected with Italy.
