MUMPS The causative agent is a filterable virus. It is found in the saliva of patients, where it may be present for at least 24 hours before swelling of the salivary glands develops, and throughout the entire period of glan­dular enlargement. Spread is by droplet infections or direct contact with materials contaminated with infected saliva. Most cases occur in children between 5 and 15 years of age; the disease is unusual in children under 2 years. Infants up to 10 months ordinarily are immuned. However, the dis­ease may occur at any age, and cases in the older age groups may be seen. After an incubation period of 14 to 21 days onset is marked by chilly sensations, headache, anorexia and malaise. This is accompanied by a low to moderate fever which may last from 12 to 24 hours before any involve­ment of the salivary glands. In mild cases, these prodromal symptoms may be absent. Pain on chewing or swallowing is the earliest symptom of parotitis. There is marked sensitivity to pressure over the angle of the jaw. With development of parotitis, the temperature frequently rises to 103 or 104 F. Swelling of the gland reaches its maximum about the 2nd day and is associated with swelling, involving the cheek and area below the ear. In most cases, both parotid glands are involved. Occasionally the submaxillary and sublingual glands also may be swollen, or, more rarely, may be the only glands affected. In such cases, there is swelling of the neck beneath the jaw. The diagnosis of typical cases during an epidemic is simple, but spo­radic cases present a more difficult problem. Swelling of the parotid or other salivary glands due to the mumps virus must be distinguished from: (1) bacterial parotid involvement, occuring in streptococcal throat infec­tions, diphtheria, or debilitated patients with poor oral hygiene, typhoid or typhus fever; (2) malignant tumors of the salivary glands; (3) postop­erative parotitis. In uncomplicated mumps, prognosis is extent. However, relapses may occur occasionally after about 2 weeks. In complicated cases, deafness or facial paralysis has been known to occur following involvement of the nervous system. Choose the correct statement:
