I have come close to pneumonia a couple of times from inhaling acid reflux in my sleep. No virus, no bacteria, just acidulous gastric contents.

BTW, I’m on a Z-pack, prednisone and albuterol right now for flu-related bronchitis. I believe my five-day course of ivermectin shortened the flu symptoms materially but the pulmonary inflammation had already begun.
