What are the clinical manifestations of mumps?
The classic symptoms of mumps include parotitis in about 50% either unilateral bilateral, which develops an average of 16 to 18 days after exposure. Swelling can also be seen in the submandibular and sublingual gland in a small percentage. Nonspecific symptoms including myalgia, anorexia, malaise, headache, and low-grade fever may precede parotitis by several days. As many as 40%–50% of mumps infections are associated with nonspecific or primarily respiratory symptoms, particularly among children less than 5 years of age. Only 30-40% of mumps infections produce typical acute parotitis. In 15-20% of infections, cases are asymptomatic.

The classic symptoms of mumps include parotitis (either unilateral or bilateral), though only 30%-40% of mumps infections produce typical acute parotitis. The parotitis develops an average of 16-18 days after exposure. Swelling may also be seen in the submandibular or sublingual glands in a small percentage of cases. Nonspecific symptoms including myalgia, anorexia, malaise, headache, and low-grade fever may precede parotitis by several days. Nonspecific or primarily respiratory symptoms are the only manifestations of infection in 40%-50% of mumps cases, and particularly cases in children less than 5 years of age. Fifteen to twenty percent of mumps virus infections are asymptomatic. Are there other causes of parotitis? Yes, but only mumps causes epidemic parotitis. Parotitis can also be caused by parainfluenza virus types 1 and 3, influenza A virus, Coxsackie A virus, echovirus, lymphocytic choriomeningitis virus, human immunodeficiency virus, and other non-infectious causes such as dr
