Adult-onset Still's disease after SARS-Cov-2 infection.

Adult-onset Still's disease (AOSD) is an uncommon inflammatory disorder. AOSD and SARS-Cov-2 infection share clinical and laboratory features, including systemic inflammation. A 19-year-old woman had prolonged fever for 3 weeks, joint pain, and biological inflammatory syndrome. Post COVID-19 AOSD was diagnosed. SARS-Cov-2 infection induces many inflammatory diseases including AOSD.
