Dr. Katz Articles with Information about Coronavirus
The major medical news of this past week, certainly grim and described in many outlets as “staggering,” was the reported decline in average U.S. life expectancy since the onset of the COVID19 pandemic. …Read More
I recently contributed a quip to my social media channels I hoped might mature into an aphorism or meme: wherever dogma barks, we have a very hard time hearing one another. Whatever this puppy matures into, it represents my conviction on the matter. …Read More
We had indications quite early in the pandemic that diet quality was, if anything, trending down. On the one hand, this is entirely understandable. If ever there was a need for whatever comfort so-called “comfort foods” can provide, this was the year. …Read More
You no doubt recall the rousing motto of The Musketeers: All for One, and One for All! I trust you received that exhortation in the spirit intended, as I always did. It was redolent of loyalty, camaraderie, courage, and honor. It was “band of brothers” (or sisters) stuff that meant no one would be left behind. It was the aspiration of making the ultimate “team,” fulfilled; it was the inspiration to be worthy. …Read More
Epidemiology is the study of impacts on human populations. There is nothing in the etymology (the study of word origins) that requires exclusive application of the term to health impacts, but that is the custom in practice. That seemingly reflects our tacit consensus: those are the only impacts, encompassing both body and mind, that truly matter. …Read More
Ordinarily, diet dominates the news this time of year, and arguably with good reason. There is the turn of the calendar as reliable portent for a bounty of diet and weight-related resolutions. There is the eagerly awaited “best diets” rankings from US News & World Report– where, I note in passing, I have been privileged to serve as one among the judges for roughly the past decade. …Read More
During my most recent guest appearance at Yahoo! Finance to discuss the COVID pandemic and nothing to do with finance – a gig that has been recurring for some time now, for whatever reasons- I was asked if the darkest days of the pandemic yet lie ahead. Actually, the provocation was a bit more extreme. …Read More
Even now, in the short, dark days of this pandemic extending past the solstice and the turn of the calendar, our viral nemesis is not the greatest threat to years in life and life in years. Even now, with more than 350,000 deaths in the United States attributed to SARS-CoV-2 since this time last year, another assailant steals more of our loved ones from us, this year and every year. …Read More
As I was composing my most recent COVID reality check video commentary, principally addressing the salient, current concerns- vaccine efficacy and safety, the emergence of new viral strains- an unintended theme insinuated itself to me. I found myself reflecting on our shared experience, even within our current, emphatic divisiveness. …Read More
Assuming one becomes available to you and/or your loved ones sometime soon, should you, or shouldn’t you, roll up your sleeve for a COVID vaccine? Please indulge me in a thought experiment on our shared way to my conclusion, and recommendation. ….Read More
Many times over the years I’ve been asked to recommend a physician, or more generically- asked what to look for in a physician. Much might be said, but I always prioritize the same thing. In medicine, what I most want to hear a colleague say at least once before I know I can trust her/him- especially with the clinical care of me or someone I love, is: I don’t know. I’m not sure. ….Read More
Our current news is, of course, dominated by the pandemic, and much of it comes at us numerically. Each day brings headlines about record numbers of cases, and hospital occupancy. Such news is grave and grim, and made all the more so by comparing the quantitative thresholds of the day for cases and casualties alike to precedent, and proclaiming that things are worse now than ever. ….Read More
I am just back from my first in-person speaking engagement since the pandemic began refashioning life as we knew it. Metaphorically, at least, it was nice to get briefly above the clouds and see that the sun still shines up there, whatever the overcast travails down here. ….Read More
One need not be a specialist in Preventive Medicine to know that the best option for a train wreck is to avoid it in the first place, and keep the train on the tracks. With regard to our national pandemic response, that opportunity has come and gone these many mismanaged months of hardship and loss. ….Read More
The US Preventive Services Task Force just advised the start of routine colon cancer screening at age 45 rather than 50. This is how Preventive Medicine is supposed to work. ….Read More
Is the pandemic over, or as the kids in the back seat might put it: are we there yet? If in Sweden, the answer is apparently: yes – albeit a very begrudging and tentative yes, encumbered by doubts, caveats, and aspersions from the camp prone to parlaying the valid arguments for lockdown into moral superiority. …Read More
The combination of initial forays back to the world, work, and notably schools; plus far more testing than we did at the start of the pandemic, produces one inevitable result: surges in case counts everywhere the population wasn’t uniformly exposed already. Is this bad, and if so- how bad? Is it in some way good? Or, is it something in between? …Read More
You have no doubt heard the news that as universities reconvene students on campuses around the country, there are flares in COVID case counts. The inclination to return universities to lock down and disperse the students back home in response to this is predictable, and about as nuanced as a knee jerk reflex, give or take the knee. …Read More
An important new study in the New England Journal of Medicine had a primary objective of determining the nature of durability of antibody responses to SARS-CoV-2. In other words, the primary questions these researchers were asking were: do people show clear evidence of immunity after a COVID19 infection, and does that immunity last for months? …Read More
Our disparate inclinations famously refract the same view into opposing perceptions: a glass half full, or half empty. The anxious passions engendered by the COVID19 pandemic have greatly amplified that proclivity. Rarely has the gulf between competing versions of optimism and pessimism, or other reciprocal ideologies, yawned so great. …Read More
Roughly two weeks ago, the American Heart Association told the world that diet should be assessed routinely in clinical encounters, and that new tools were needed to make this possible. The new tools should be quick, elegant, efficient, reliable, accurate, user friendly and economical. They should interface seamlessly with electronic health records, fit without friction into clinical work flow. …Read More
I hope, my fellow Americans, that in spite of it all, you have a good holiday weekend. This is a hard time to “celebrate” America, both practically and in principle. Practically, the customary expressions of celebration are much obviated during a pandemic surge – by restrictions, regulations, cancellations, and lock-down extensions. …Read More
My colleagues, Maria Chikina and Wes Pegden, were entirely correct in their predictions of what happens when you flatten the epidemic curve without clear plans for a “phase 2” to follow. They were entirely, and obviously right- but I imagine they get no satisfaction from that, as I get none for having recognized that they were right. People in Texas, and Arizona, and Nevada; in Missouri, Alabama and Florida- are paying with their lives. …Read More
I don’t think it is much of a stretch to say the United States has responded to the challenge of the COVID pandemic by doing nearly everything wrong. Federal guidance has been inconsistent and incoherent, and while waiting for evidence that grown-ups were running the country, sensible people with more regionalized authority lost critical time, and saw vital windows of opportunity slam shut. …Read More
I was privileged yesterday morning to address the virtually assembled multitudes for the 2020 Harvard Lifestyle Medicine conference. Hundreds were gathered from throughout the US, and countries all over the world. As ever, the enthusiasm of this group ran high- albeit expressed on this occasion via texts on Zoom, rather than the smiles, hugs, high-fives, and back-pats of life as we knew it before COVID. …Read More
For much of the world, the past three months had a clear goal: “lockdown and avoid Covid-19 exposure.” But, in recent weeks, a restless public had already been transitioning haphazardly out of this stage, ranging from demands for continued isolation to massive pool parties and “liberate my state” rallies. With the addition of large gatherings and protests of the past week, confusion and anxiety have even further grown. …Read More
There is a trait other than skin pigment that we humans do seem to share all but universally: a rather short attention span. A veritable “moment” before the COVID19 pandemic began rewriting the modern history of public health practice, fixating our attention, and propagating our miscellaneous anxieties, we had declared another epidemic here in the United States a national emergency, after considerable debate and dithering. …Read More
One could be forgiven for thinking that however bad it is to be in the middle of one pandemic, it would be worse to be in the middle of two at the same time. In fact, though, we are very much in the middle of two- and at least through one pertinent lens, two pandemics are better than one. …Read More
My fellow Americans- and to be ecumenical about it, my fellow humans- I have two questions for you. Do you have at least half a wit? And, do you have at least half a heart?
If the answers are yes- you have at least half of each- then I contend it’s time to come out of opposing corners and meet in the middle of the COVID infodemic. Enough of the polarizing nonsense that passes for COVID policy debate in this country. Seriously: enough.
We must, to some extent, be something like flotsam in the currents of culture, debris on the winds of the Zeitgeist; a bit helpless against the buffeting of “now,” in all its particulars.
Perhaps it is the Internet and social media; perhaps the constant immediacy of news cycles. Whatever the reasons intrinsic to “now,” they exert some dominion over our thinking, and seemingly the dictates of now call for: pretty dumb. …Read More
I have had abundant opportunity to share my various reflections on the COVID19 crisis. This week, I had the chance to do so directly before the Homeland Security Committee of the United States Senate, and at full length and leisure in a podcast interview with my friend, Rich Roll. What’s left?
Hope, and consternation. …Read More
We updated previous estimates (wwwnc.cdc.gov/eid/article/26/8/20-0679_article) of adults with any underlying condition increasing risk of complications from COVID-19 using recent US hospitalization data instead of mortality data from China. This substitutes obesity for cancer in the definition and increased the percentage of adults reporting more than 1 condition to 56.0% (95% CI 55.7-56.4). …Read more
This past weekend, the World Health Organization stoked the flames of global anxiety by issuing this in the guise of a reality check: we do not know that getting COVID19, and recovering from it, results in immunity. …Read more
Having just completed three 12-hour shifts as a volunteer physician at a hospital emergency department in the Bronx, I can tell you this: it would be bad not to get a N95 mask, but getting one is no walk in the park, either! You try wearing one for 12 hours straight, and then let’s talk. …Read more
Thomas L. Friedman of The New York Times: With each passing day it becomes more obvious how unlucky we are that one of the worst crises in American history coincides with Donald Trump’s presidency. To get out of this crisis with the least loss of life and least damage to our economy, we need a president who can steer a science-based, nonpartisan debate through the hellish ethical, economic and environmental trade-offs we have to make. …Read more
We are, no doubt, all comparably eager to consign this blighted interval- of coronavirus contagion, social upheaval, recrimination and fear – to the history books. One day, this will all just be a reference in a tale told to grandchildren, an episode stripped of its visceral impacts and neatly archived. …Read more
Believe it or not, now- with the acute threat of COVID19 constraining our activities and propagating our anxieties- there may have never been a better time to address and improve the chronic state of our health, both as a population, and as individuals. Timing, timelines, and the newfound time at our disposal- really are of the essence. …Read more
Much has been made of my early contention that the coronavirus could hurt and kill people more than one way, and that we needed to do our best to interdict them all. I called the approach – that would keep those vulnerable to severe infection and the direct harms of the virus away from it, while allowing those more prone to harm through a degradation of services, goods, livelihoods, supply chains and the social determinants of health back to the world early – vertical interdiction. …Read more
There is no debate, and never was among serious people, about the need to keep those at high risk for severe coronavirus infection and this very nasty germ – SARS-CoV-2- apart. There is only debate about how. Any suggestion to the contrary is misunderstanding, willful or inadvertent, or the replacement of actual ideas with caricatures of them. …Read more
Ordinarily, I work to draw attention away from the crude, bland, anonymizing statistics of public health to the faces they veil, the human stories they obscure.
But as the coronavirus pandemic becomes an ever more proximal menace, affecting more people we all know and love- I see a need to go the other way, and highlight the use and misuse, the lessons and liabilities of numbers, in and out of context. …Read more
Of the slightly more than 30,000 total, global deaths from coronavirus to date, a third of them all have been in Italy. That sad distinction means Italy is the source of our best potential insights about COVID19 and the risk of severe infection and death.
Only in a world of ideologues and demagogues, of propagandists and Internet trolls, are our options limited to: “send everyone back to the world by some arbitrary date, and never mind the body count” versus “everybody’s grandparents in coronavirus lockdown until many of them die of other causes before ever again hugging their grandchildren.” Indefinite lockdown and indiscriminate largess are two variants on a common theme of heartless, thoughtless public health carnage. Of course there is another way. …Read more
I am just back from being tested for COVID19- very efficiently and professionally, I might add- at Griffin Hospital in Derby, CT. I can’t commend my Griffin colleagues enough for how beautifully they organized. Below are images of the test facility, and the print guidance I received. That said, I won’t have my test results for 3 to 5 days, which is far too long- not just for me, but for the system that needs those data to understand and best address the pattern of the epidemic. …Read more
Thomas L. Friedman of The New York Times: One of the best ideas I have come across was offered by Dr. David L. Katz, the founding director of Yale University’s C.D.C.-funded Yale-Griffin Prevention Research Center and an expert in public health and preventive medicine. Katz wrote an Op-Ed in The Times on Friday that caught my eye. He argued that we have three goals right now: saving as many lives as we can, making sure that our medical system does not get overwhelmed — but also making sure that in the process of achieving the first two goals we don’t destroy our economy, and as a result of that, even more lives. …Read more
The New York Times: If we were to focus on the especially vulnerable, there would be resources to keep them at home, provide them with needed services and coronavirus testing, and direct our medical system to their early care. I would favor proactive rather than reactive testing in this group, and early use of the most promising anti-viral drugs. This cannot be done under current policies, as we spread our relatively few test kits across the expanse of a whole population, made all the more anxious because society has shut down. …read more
COVID-19 is not an even-handed scourge. The risk of severe coronavirus infection, and death, are highly concentrated among those over age 80, to a lesser extent among those over 70, and in particular where baseline health is already poor. To maximize the efficiency of our harm reduction efforts- containment, prevention- they should be targeted accordingly. …read more
No one will know for sure the best responses to the COVID-19 pandemic until after it’s all over, and we look back and second guess ourselves. Hindsight will approximate 20/20; foresight almost never does…my view is that we are under-testing, over-reacting, and somewhat misdirecting our efforts. …read more
There’s no way to watch the COVID-19 drama unfold and not be concerned/anxious (as if we needed another reason for anxiety these days!). My primary point early on- here – was that we exaggerate the ‘new and shiny’ risk relative to more familiar perils. That remains true of COVID-19 almost no matter how bad it gets. …read more
The ultimate questions- will I get this disease, and will it kill me if I do?– can be broken into component parts. The first is, what is my risk of exposure? Right now, unless you are in one of the rarefied populations around the world where the disease is concentrated, the answer is- probably very, very, very low…read more
Perhaps our species will decide before it is entirely too late to stop soiling our nest – although that’s far from clear. Perhaps we will decide to stop ravaging and blighting the only planet we will ever call home while it remains hospitable to our kind. …read more
Wouldn’t the Devil you loathe and fear appear disguised, deceive, and evoke your sympathy? Wouldn’t the Devil you believe in and shun, attract rather than repulse you? Wouldn’t he assuage you to his side of every argument? Wouldn’t he make you love him, and hate those who called him out for the hate he sowed, and the evil he did? …read more
I’ve noticed the inevitable during my travels of the past week: a whole lot of anxious conversations about the coronavirus. This is not entirely unfounded- the pandemic is alarming. For those wanting good, up-to-date, expert intelligence about the virus, its spread, the risks, and suitable responses- they are available…read more
Poor overall diet quality is the single leading cause of premature death in the United States today, causing an estimated 500,000 or so deaths each year. That is more than ten times worse than a fairly bad strain of influenza, monumentally worse than coronavirus thus far, and happens every year. ….read more
I happen to be a board-certified specialist in Preventive Medicine and Public Health…it is in my training, if not my DNA, to prevent the preventable calamity. My duty is to perceive vulnerability, peril, and imminent danger to life and limb- and do my utmost about it in advance…read more
