AB  - A previously healthy 53-year-old man was hospitalised for 12 days due to COVID-19 
      with shortness of breath. A few days after discharge from hospital, the patient 
      developed fever and severe pain in several joints in the lower extremities. The 
      pain was so severe that the patient was unable to stand on his feet. Synovial 
      fluid from the right-side knee contained a high number of polynuclear cells and a 
      few mononuclear cells. Microscopy, culture and PCR tests for bacterial infection 
      were all negative. Furthermore, the patient tested negative for rheumatoid 
      factor, anti-cyclic citrullinated peptide and human leukocyte antigen (HLA)-B27. 
      Thus, the condition was compatible with reactive arthritis. The condition 
      improved markedly after a few days' treatment with non-steroid anti-inflammatory 
      drugs and prednisolone.
