Overall, 59.0% (82\/139) of people with Covid\u201019 had mild disease, 36.7% (51\/139) had severe disease, and 4.3% (6\/139) had critical illness. Eighty\u2010two (59.0%; 95% CI: 50.3 to 67.3) reported new headaches during the acute phase and 3.6% (5\/139) had persistent headaches 1\u00a0month after fever and dyspnea remission. Anosmia and ageusia were also very common, occurring in 60.4% (84\/139) and 58.3% (81\/139) of the patients, respectively. These 2 symptoms persisted in 14.4% (20\/139) and 11.5% (16\/139) of Covid\u201019 patients 1\u00a0month after recovery. Headaches were neither clearly associated with anosmia, nor with ageusia, and were not associated with disease severity (ie, requiring hospitalization or intensive care unit).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This specific study highlights the high prevalence of new headaches during Covid\u201019 infection in French patients.
