I had it in September of 2020. Eleven days with 103F temp, then after the fever broke I spent 8 days on supplemental oxygen. Doc was very pleased with my recovery considering how bad I'd had it. On the bike, I was probably 80% last year (2021) and strengh-wise I was fully recovered by this year; but my endurance was just starting to return by the end of this year (2022). For basically the last two years, if I rode 30-40 miles I'd need several days to recover, no matter how easy I took it. Hopefully I'll be ready for some metrics next year.
