1/ Why do doctors like me & @meganranney ask how high the POTUS' fever has been, if his O2 levels have been low, whether he's required supplemental oxygen? It's the difference between moderate & severe COVID. This tells us a lot about prognosis & what treatments are indicated.
2/ If the president required supplemental oxygen, he has SEVERE COVID and should hand power over to VP Pence until he is clinically improved.
3/ POTUS was given remdesivir. *Assuming* evidence-/guideline-based use of remdesivir, this would also indicate that the president has SEVERE COVID (i.e. oxygen saturation less than or equal to 94% on room air, requiring supplemental oxygen/ventilator/ECMO).
4/ But we know the president doesn't abide by evidence and guidelines, so it's hard to know for sure if that's what his receiving remdesivir means.
5/ Dr. Sean Conley, the president's personal doctor, ended the press conference when asked whether the president had received dexamethasone. Dexamethasone is indicated in severe/critical COVID, but not mild/moderate COVID.
6/ Assuming a non-denial = tacit affirmation, the president has received dexamethasone. This would mean he has (at the very least) SEVERE COVID. He should transfer power to VP Pence until he's clinically improved.
7/ There are reasons NOT to give dexamethasone if COVID is not severe enough: psychiatric side-effects (e.g. agitation, confusion), suppression of adrenal glands, risk of bacterial/fungal infection. I don't think the decision to give dexamethasone would be cavalier.
8/ The questions Dr. Conley is avoiding / refusing to answer (highest temperature, lowest oxygen saturation, requirements for supplemental oxygen, need for dexamethasone) would tell us something about the president's prognosis. THE LACK OF TRANSPARENCY IS, ITSELF, A DIAGNOSIS.

1/ I explain how RFK Jr's plans could affect Americans' health.

He is known for falsely claiming that vaccines cause autism & other health issues.

cbsnews.com/video/doctor-e…
2/ RFK Jr: "The problem with the measles vaccine is that it's a leaky vaccine. It doesn't provide sterilizing immunity."

It's true that the measles vaccine doesn't prevent ALL infections.

It's ~97% effective after 2 doses.
3/ In rare cases, vaccinated people may get infected & transmit the virus to others.

This is all the more reason for vaccinating everyone in a community, not just those who feel like it.

1/ RFK Jr. to lead @HHSGov US Dept of Health & Human Services

with @AdrianaDiaz & @tonydokoupil on @CBSMornings
2/ Kennedy has criticized multiple public health agencies he could now lead.

He's said the @US_FDA's "war on public health is about to end," claiming the agency suppresses anything that "advances human health & can't be patented" by pharmaceutical companies.
3/ But Kennedy's statement demonstrates a common misunderstanding about public health authorities in te US.

We are the United States of America — public health powers reside at the state level.

1/ Yesterday, the @WHO declared mpox a public health emergency of international concern (PHEIC).

This is the 2nd time in 2 years that the WHO has declared a PHEIC for mpox.

with @vladduthiersCBS on @CBSMornings
2/ There have already been more than 17K cases in Africa so far this year – more than the total for all of last year.
3/ @WHO announces a Public Health Emergency of International Concern (PHEIC) when there is a significant risk to global health & it requires an internationally coordinated response.

A PHEIC:
🔹helps marshal funding for a public health response
🔹pressures governments to act

2/ A new study published in the JAMA Health Forum yesterday found that:
🔹mask requirements & vaccine mandates were associated with ⬇️ deaths
🔹prohibitions on vaccine or mask mandates were associated with ⬆️death rates

3/ Activity limitations (e.g. closing schools, restaurants, bars; stay-at-home orders; restrictions on leisure time activities & public gatherings) likely provided minimal benefit while imposing substantial cost.

1/ New Hope Against Dementia: study says singles vaccine also appears to delay onset of dementia
with @CBSMornings' @tonydokoupil @AdrianaDiaz @nateburleson
2/ A study published yesterday in Nature Medicine found that the new Shingrix vaccine was more protective than the old Zostavax vaccine in delaying dementia.

The Zostavax shingles vaccine was discontinued after the Shingrix vaccine was approved.

3/ The Shingrix vaccine is also more protective than Zostavax in preventing shingles.

Shingles is caused by the varicella-zoster virus (VZV), a herpes virus that also causes chickenpox.
