Chapter 23 update patches.

Mumps is an acute viral illness caused by a paramyxovirus. It is usually characterised by bilateral parotid swelling, although it may present with unilateral swelling. Parotitis may be preceded by several days of non-specific symptoms such as fever, headache, malaise, myalgias and anorexia. Asymptomatic mumps infection is common, particularly in children (Plotkin and Orenstein, 2004).
