Q

A 32 year old woman suffering from arthritis and rash on her face with evidence of viral DNA in the synovial fluid?

A

Parvovirus B19 (Parvovirus B19 has ssDNA and erythema infectiousum can occur in children and sometimes in adults; it can cause immune complex arthritis with rash. Rubella has ssRNA so it can’t be the answer; it presents with maculopapular rash on face. HBV has dsDNA and may lead to arthritis-dermatitis syndrome (immune complex mediated). HCV is also ssRNA and presents with myalgia and cryoglobulinemia)
