Viral arthritis?,”Viral arthritis presents with the acute onset of polyarticular and symmetric arthritis that resolves within two months. Parvovirus is amongst the most common causes of viral arthritis, and is particularly likely in adults who have frequent contact with children, such as day care workers. Parvovirus in adults most often presents with arthritis/arthralgias involving the MCP, PIP, and wrist joints. The “”slapped cheek”” appearance is unusual in adults, and the presence of systemic symptoms is variable.There is a lack of inflammatory markers
and resolution typically occurs within 2 months. Viral arthritis can mimic inflammatory arthritides such as rheumatoid arthritis. Arthritis must be present for at least 6 weeks in order to diagnose rheumatoid arthritis.”
