Mumps is a highly contagious viral infection with an incubation period of 14-18 days from exposure to onset of symptoms. The duration of the disease is approximately 10 days.
The initial symptoms of mumps infection are nonspecific (low-grade fever, malaise, headache, muscle aches, and loss of appetite). The classic finding of parotid gland tenderness and swelling generally develops the third day of illness. The diagnosis is generally made without the need for laboratory tests.
Serious complications of mumps include meningitis, encephalitis,deafness, and orchitis.
The MMR vaccine provides 80% effective immunity against mumps following a two-dosage schedule (12-15 months with booster at 4-6 years of age).
No specific therapy exists for mumps. Warm or cold packs for the parotid gland tenderness and swelling is helpful. Pain relievers (acetaminophen [Tylenol] and ibuprofen [Advil]) are also helpful.
Painful swelling of the salivary glands classically the parotid gland is the most typical presentation. Painful testicular swelling (orchitis) and rashmay also occur. The symptoms are generally not severe in children. In teenage males and men, complications such as infertility or subfertility are more common, although still rare in absolute terms. The disease is generally self-limiting, running its course before receding, with no specific treatment apart from controlling the symptoms with pain medication.
Fever and headache are prodromal symptoms of mumps, together with malaise and anorexia. Other symptoms of mumps can include dry mouth, sore face and/or ears and occasionally in more serious cases, loss of voice. In addition, up to 20% of persons infected with the mumps virus do not show symptoms, so it is possible to be infected and spread the virus without knowing it.Males past puberty who develop mumps have a 1520 percent risk of orchitis, painful inflammation of the testicles.
