1. We heard that statement from Dr. Lisa Bardack, "who examined her at her home in Chappaqua." Bardack said, "On Friday, during follow up evaluation of her prolonged cough, she was diagnosed with pneumonia." I can't tell from that whether Bardack is the one who did the examination on Friday and gave the diagnosis of pneumonia. Perhaps Bardack is cagily relating what some other doctor saw fit to say to Clinton, and Bardack herself does not believe that is the correct diagnosis. I'm assuming Bardack will not lie, which is why I'm noticing the particular words and the distance Bardack has taken from that diagnosis.
2. Bardack also said, after Clinton's collapse yesterday at the 9/11 event, that "she became overheated and dehydrated," and "she is now re-hydrated and recovering nicely." This seems like a separate diagnosis apart from the diagnosed-on-Friday pneumonia, or is that supposed to be a consequence of the pneumonia? Bardack does seem to be attaching her reputation to the assertion that Hillary "became overheated and dehydrated," but that's just a statement of the symptoms, not why they happened. It wasn't a hot day, but Hillary might have become hot because of the bright sun and her heavy clothing. I just can't tell from Bardack's statement whether there is some underlying medical problem that would lead to overheating. What's the diagnosis, the reason for overheating? I don't think Bardack said anything that even purports to be an answer to that question.
3. NBC — the news site at the link above — has a health news reporter explaining the concept of "walking pneumonia" — "patients don't feel great, but they're not sick enough to stay home in bed or to be hospitalized.... Pneumonia can be caused by viruses or bacteria [or fungi], and it refers to an infection that gets into the lungs. Bacterial pneumonia is common, usually not serious and easily treated with antibiotics." Since Bardack told us that Hillary Clinton "was put on antibiotics," it might mean that the diagnosis was bacterial pneumonia, but it might mean that antibiotics were given because they'd work if it's bacterial, and it might be bacterial, so try antibiotics because they might work. If not, we know it's viral... or fungal... or bacteria that didn't respond to that antibiotic... I don't know.
4. "Walking pneumonia" is not a technical term, and it seems particularly infelicitous when Hillary quite conspicuously could not walk.
5. I think it's fair to say that the Clinton campaign has been withholding information about Hillary's health and that it intends to continue to withhold as much as it can. The Bardack statement seems only to push us back in a hope that we will not ask for more, and that came only after a very dramatic, impossible-to-ignore video of Hillary collapsing.
