1/ Covid ( @UCSF) Chronicles, Day 205

It’s hard to believe that we first learned of Trump’s Covid diagnosis exactly one week ago https://tinyurl.com/yxq2vbv3 .">https://tinyurl.com/yxq2vbv3&... Here are a bunch of hot takes on today’s issues, which continue to move at hyper-speed.
2/ On Trump’s clinical status. Yesterday, his doc reported that Trump& #39;s vital signs were stable, including normal oxygen saturation w/o supplemental O2. Today’s videos show no obvious shortness of breath (he completes sentences without stopping for air): https://tinyurl.com/y3p9l8lh ">https://tinyurl.com/y3p9l8lh&...
3) Based on his @FoxBusiness phone-in today https://tinyurl.com/y5h5brpe ,">https://tinyurl.com/y5h5brpe&... his mental status & judgment seem to be at his baseline (that& #39;s the standard we use). Whatever you think about Trump& #39;s mind, there’s no new evidence of lack of capacity to do his job based on Covid or meds.
4/ Again, per his doctor’s note yesterday https://tinyurl.com/y43v9tuu ,">https://tinyurl.com/y43v9tuu&... Trump& #39;s fever is gone, which could be true improvement or masking of fever by steroids or antipyretics.

But overall, Trump seems stable. With each day, his odds of survival improve.
5/ As of last Friday, as a high-risk Covid patient w/ high fever and low oxygen who needed hospitalization, he probably had a 1-in-5 chance of dying from this episode. There& #39;s no great data to give a precise estimate now, but given stability on day 7, mortality rate is probably…
6/ … now more like 1-in-20.

Note that it is decidedly not zero – many Covid patients (most famously Herman Cain https://tinyurl.com/yxco3acb )">https://tinyurl.com/yxco3acb&... were stable after week 1 and went on to crash in week 2 or 3. Of course, it’s hard to extrapolate from…
7/ … the literature, given that Trump enjoys around-the-clock care in his home, can return to the hospital by helicopter, and has received 3 medications, one of which (monoclonal antibodies) is not available to other patients, outside of a clinical trial.
8/ But the odds – that he will avoid re-hospitalization, the ICU, intubation, and death – are now favorable. His symptom course is harder to predict, partly because we really don’t know what his current symptoms are and partly because…
9/ … his symptoms may be masked by steroids, which will be stopped in a few days (usual course is 10 days; the remdesivir was probably stopped Tuesday after day 5; the monoclonals were a single shot last week). But here too, if he remains asymptomatic…
10/ …through the first 10-14 days, he’s likely to have a fairly benign course overall. Moreover, it’s unlikely, though not impossible, that he’ll have serious symptoms later (ie, be a long-hauler).

On the other hand, whether he& #39;ll have long-term heart and lung involvement…
11/ is hard to predict – unfortunately, many patients do, even if they had a mild initial course. For example, this study found MRI evidence of heart inflammation in 60%; it didn& #39;t vary by initial severity https://tinyurl.com/y6plsg97 .">https://tinyurl.com/y6plsg97&... The clinical meaning of this is not yet known.
12/ We also learned Trump tested positive for antibodies yesterday. That’s likely from the monoclonal antibodies he received https://tinyurl.com/y59kkjq5 ;">https://tinyurl.com/y59kkjq5&... had he not gotten them, it would be early to test + for antibodies (it usually takes 10-14 days). Overall, it doesn’t mean much.
13/ There is no way to prove whether the monoclonal antibodies (actually called REGN-COV2, though Trump calls them “Regeneron,” which is the name of the company) contributed to his benign course so far, though they may have.
14/ He calls it a “miracle cure.” This, of course, illustrates his (mis)understanding of science. Previous Trumpian “miracles,” you’ll recall, included hydroxychloroquine (proven ineffective), convalescent plasma (jury is out), bleach ( ), & the virus itself, just going away.
15/ When he received the antibodies (it’s not clear whether he was hypoxic yet), he probably had an 85-90% chance of surviving this episode, independent of that experimental treatment. This is why we do randomized trials, with active drug in one arm of the study...
16/ … and placebo or “usual care" in the other. If he continues to do well, it could be due to the antibodies, or to the other 2 meds (remdesivir or dexamethasone), or some combo of them, or luck. There’s simply no good way to known when looking at a single patient’s course.
17/ It follows, then, that the President’s course should have precisely zero influence on public policy, including the cost of the drug or its @US_FDA approval prospects. But that’s not the way Trump thinks, nor, in turn, the stock market. https://tinyurl.com/y3c5w3gy ">https://tinyurl.com/y3c5w3gy&...
18/ Turning to next week& #39;s debate: the Commission on Presidential Debates announced today it intends to hold the second debate, scheduled for next Thursday, virtually. Trump immediately rejected the decision https://tinyurl.com/y34jkbjs ">https://tinyurl.com/y34jkbjs&...
19/ The Commission& #39;s decision is wise. Knowing when a Covid patient is no longer contagious is tricky: the @CDCgov guideline says it& #39;s 10 days after symptoms began, but 20 days for patients with severe symptoms or compromised immunity https://tinyurl.com/y3e3t3az ">https://tinyurl.com/y3e3t3az&...
20/ Trump’s symptoms began last Thursday, we believe. So next Thursday would be ~14 days. Although he doesn’t have a known immunity problem, he’s now on an immunosuppressant, dexamethasone.

Unfortunately, there is no available test to allow for 100% certainty re: infectivity.
21/ The problem w/ testing is that a negative test can be wrong (so can a positive – late in the illness it can represent dead virus). For a high risk person (Biden, age 77, is) to stand mask-less, 12 ft away from a mask-less patient with recent Covid who is talking loudly…
22/ … for 90 minutes when said patient has even a 1% chance of still being contagious would be far too risky. If I were advising Biden, I would tell him that the right call is to hold the debate virtually, or not at all.
23/ When I first heard of Trump’s diagnosis, I hoped this would serve as a teachable moment for the US – one that might advance the science & change public attitudes in a way that could save many lives https://tinyurl.com/yynz7mlc .">https://tinyurl.com/yynz7mlc&... But as @murphymike says, Trump is the "atomic clock":
24/ totally predictable & unchanging. By minimizing the role of health measures (incl masking & contact tracing), downplaying the virus& #39;s severity because he (may) be getting lucky, touting unproven therapies & framing himself as a survivor due to his own powers of personality...
25/ (implying that those who died lacked such fortitude; read: losers), he continues his record of Covid-19 failure. The hope that illness would lead to humility & compassion for millions of sickened & 210,000 dead Americans was to ask too much. Now I simply wish him good health.
