Viral infection may cause sudden onset polyarthralgia or polyarthritis. Recognizing viral syndromes during the acute phase of illness is critical as markers of acute infection may fade during convalescence. While joint symptoms and signs in many cases are self limited, in others joint involvement may persist for months to years. Acute and chronic findings may resemble classic idiopathic diseases such as rheumatoid arthritis or systemic lupus erythematosus. Some viral infections may manifest with rash, vasculitis, or organ involvement. Understanding of epidemiology, geography, clinical presentation, virus behaviour and host response assists diagnosis and selection of appropriate management. Understanding virus-host interactions may offer insights into mechanisms of pathogenesis in idiopathic rheumatic diseases.
