Viral arthritis and vasculitis are important differential diagnoses primarily in patients with acute polyarticular arthritis in association with fever and rash, in populations specially at risk and in returning travellers. Parvovirus B19 is the most frequent cause of viral arthritis in Europe, whereas rubella, hepatitis B and C viruses have become less common. Due to worldwide tourism arthritogenic alphaviruses, which are transmitted by mosquito vectors have come into the focus of tropical medicine and rheumatology. Viral arthritis is typically self-limiting but due to severe pain often requires symptomatic therapy with nonsteroidal antirheumatic drugs; however, arthritis and vasculitis may also be a manifestation of an important treatable viral infection, such as hepatitis B, C and human immunodeficiency viruses (HIV).
