RSV is the worst virus I've had in a decade, probably since I had shingles in my twenties. My daughter brought it home from daycare and both my partner and I had a low-grade fever for 2 weeks, and a bad dry cough for another 2 weeks after that that would wake us up multiple times a night. Daughter bounced back in about half the time. By contrast, Covid hit us all recently and we were all 100% within the week. Your mileage may vary.
