Symptoms lasting 12+ months were linked to 2x worse perceived economic status, despite stable household income. Prevalence: 13% at 3 months, 11% at 6 months, 6% at 12 months. No differences in actual income or work attendance in Japanese cohort. (n=2,756) #LongCovid

Microvascular function was reduced in patients vs recovered controls, independent of fitness level. Muscle oxygen reperfusion rate lower even after adjusting for cardiorespiratory fitness. May explain persistent muscle fatigue in case-control study. (n=62) #LongCovid

Fatigue affected 78-98% of workers with persistent symptoms after occupational infection. Cognitive fatigue in 78-93%, physical fatigue in 87-98%. Higher acute symptom count linked to lower cognitive fatigue odds. Median age 54, 77% female in German registry study. #LongCovid

ME/CFS patients' sleep efficiency varied 40% more night-to-night than healthy controls, despite keeping steadier bedtimes Matched case-control study using 7-day activity tracking found patients spent 1hr+ more in bed but achieved same total sleep hours (n=76) #LongCovid
