My parents went on a two week vacation to Switzerland and have been back in the United States for around a week. In the last few days they’ve gotten very sick. The symptoms seem like covid or the flu, but my dad said their doctor ruled those out as well as strep throat. I’m sure they ran additional tests as well. Has anyone heard about something like this going around? Should I be concerned? FWIW I’ve been around them the entire time they’ve been sick and I haven’t caught anything.
COVID/flu symptoms are the same symptoms as a lot of things, so hard to say anything about what they have based on those symptoms. If their doctor is decent, your best advice is to just let them do their thing. You’re not going to get a useful diagnosis from the Lemmy community.
I should stop there, but I came here to answer the title of your post. Yes, my dad died of something they never figured out. Was very strange.
