Peter Attia MD#102–Michael Osterholm, PhD: COVID-19—Challenges ahead & reasons for optimism and concern
At a glance
WHAT IT’S REALLY ABOUT
Osterholm Warns of Prolonged COVID-19 Spread, Shortages, and Limited Easy Solutions
- Osterholm says he expects transmission to continue until roughly 50 to 70% of the population is infected unless it is suppressed, and sees no easy path between a Wuhan-style shutdown and uncontrolled spread.
- He argues the US case fatality rate could land at 1 to 2.5% because of obesity, older age, and neglected long-term care facilities, while Attia says that would mean more Americans dying than from all other causes combined.
- Osterholm describes supply chain collisions affecting critical ICU drugs, N95 respirators, and testing reagents that he expects to raise mortality and limit testing just when it is most needed.
- He says a vaccine is unlikely before about 18 months because of antibody-dependent enhancement safety concerns and limited manufacturing capacity, and that therapeutics data should arrive sooner.
- The two discuss uncertainties in modeling, R0, super-spreader events, pre-symptomatic transmission, and weak global coordination, with Osterholm noting a macaque re-challenge study as one source of hope for durable immunity.
IDEAS WORTH REMEMBERING
5 ideasOsterholm expects prolonged transmission without an easy way out
He sees three options: suppress with a draconian shutdown, let it spread and overwhelm hospitals, or attempt a middle path that protects the vulnerable while keeping essential work going.
Macaque study offers hope for short-term immunity
Osterholm cites a study in which recovered monkeys were protected on re-challenge a month later, which he takes as a sign of at least short-term durable immunity.
CFR depends heavily on who is infected and underlying health
Osterholm notes that missed deaths in the numerator affect the rate more than added cases in the denominator, and he cites differences between Korea and Italy by age and the risk of obesity and long-term care exposure in the US.
Supply chains may drive deaths as much as the virus
He describes 156 critical generic drugs, about 85% made abroad and many in China, plus limited N95 production of about 35 million a month from 3M versus an estimated need of 400 million or more.
Testing will likely decline just as demand rises
Reagents are drawn on globally and partly made in China, so Osterholm says testing will implode and officials will need to lean on influenza-like illness surveillance and treat symptomatic patients as presumed COVID.
WORDS WORTH SAVING
5 quotesI've come to the point in my old age that when something walks like a duck, looks like a duck, and quacks like a duck, I think it's probably a duck.
— Michael Osterholm
We don't send our soldiers into war without some kind of protective equipment or without bullets in their guns. We send healthcare workers into this viral battle, and we're gonna be sending them in without bullets or without protective equipment, and that to me is really sad
— Michael Osterholm
If there's an operative set of words in this whole entire experience, it's supply chains, supply chains, supply chains.
— Michael Osterholm
Trying to stop this kind of transmission is like trying to stop the wind.
— Michael Osterholm
We throw around a lot of numbers, and we have to never forget these are all people. They're our loved ones. This is real, and more people are gonna know somebody in the next couple of weeks that are gonna be seriously ill or die.
