We don't have a good handle on the real long-term long Covid patients (the 6-12+ month kind), but it's definitely not rare. I had one patient with it referred to me, but also out of the 30 or so patients in my practice who got Covid earlier in the year, 2 had some Long Covid symptoms (one is my partner's healthy 30 year old son who has just a week of flu-like symptoms and loss of smell in March in NYC, but still now has intermittent days of severe fatigue and some cardiac symptoms. )
Overall, I'd say 10-20% of my outpatient mild-to-moderate cases have had some long-term sequelae. I've seen new onset diabetes, new onset asthma, hearing loss, orchitis (inflammation of the testicles which can cause infertility), one patient had to go on oxygen at night - not to mention the people who just had a cough and fatigue for 5 months.
