Mumps is a viral illness characterized by fever, swelling, and tenderness of the salivary glands, with the parotid gland most commonly affected. The disease is seen most commonly in the winter and spring months and is communicable 1 week to 10 days after the onset of parotitis. Nonsuppurative parotid swelling is the hallmark of mumps. The swelling can be unilateral or bilateral and is sometimes associated with trismus. Less commonly, patients experience epididymoorchitis, which also can be unilateral or bilateral, and meningitis. The CSF in these cases usually demonstrates a lymphocyte pleocytosis and low glucose. Rare complications include transverse myelitis, Guillain-Barre syndrome, pancreatitis, myocarditis, and deafness. Treatment is supportive.
Cough, coryza, and conjunctivitis (A) is associated with measles (Rubeola) and precedes the characteristic maculopapular rash by 2 to 4 days. The classic rash of measles is maculopapular (C) and begins on the head and progresses downward over the body over a period of 3 days. Epididymoorchitis (B) is associated with mumps, but much less common than nonsuppurative parotid swelling.
