Mumps is an acute, usually self‑limited systemic illness characterized by parotiditis, high fever, and fatigue. One third of infections are asymptomatic. The presence of mumps IgG antibody suggests immunization or past or current infection with mumps virus. The presence of IgM antibody to mumps typically indicates recent or current mumps infection; however, false positive results may occur due to antibody cross reactivity to parainfluenza virus.
