How many lesions did you have at diagnosis?

Apparently I have at least 20 (brain) and a few on Cspine. Doc said counting more than 20 wouldn't be helpful. I obviously have so many questions for myself lol but curious what is the average number ppl have at time of diagnosis?? One doc said covid could have caused MS, which I hope not bc that would mean 20+ lesions developing within 10 weeks 😬
