The article by "Mayo Clinic Staff" says that "Even in young people, COVID-19 can cause strokes" but there is no link to show which of the 16 references might back that up. The blog post from Harvard says "even young individuals are seven times more likely to have a stroke from this coronavirus versus a typical flu virus" with a link to an article in The Lancet "COVID-19 related stroke in young individuals". The Lancet mentions "a 7.6-fold increase in the odds of stroke with COVID-19 compared with influenza" citing Merkler which says "The youngest patient with ischemic stroke in the cohort was age 51 years." The Lancet also describes "a 7-fold increase in the rate of large vessel stroke in young people compared with the previous year" citing Belani which gives a median age of 65.5 ± 15.3 for the 41 cases and does not mention a minimum age.
