How Long Is Influenzaの注目ポイントを分かりやすくまとめてご紹介します。

Full recovery—the moment you can walk up a flight of stairs without gasping—usually happens around the two-week mark. But that lingering “blah” feeling can stick around for another week. You’ll feel off. Your brain will be foggy. You’ll forget your own phone number. It’s like your body is slowly rebooting after a major crash. So, be patient. Eat some soup. Drink all the water. And remember: you are not alone in that misery—every single person reading this just nodded.

So, to answer your original question: influenza is about a week of pure chaos, followed by two weeks of a lingering cough, and a month of feeling like a slightly damp version of your former self. It’s the uninvited guest who eats your snacks, breaks your couch, and leaves without saying thank you. Treat it with rest, fluids, and low expectations. You’ll be back to normal eventually—just in time for allergy season to start.
