Mumps Info

Una guía sobre paperas que cubre los signos y síntomas, prevención y tratamiento.

Mumps is a viral disease caused by the mumps virus.Initial signs and symptoms often include fever, muscle pain, headache, poor appetite, and feeling generally unwell.This is then usually followed by painful swelling of one or both parotid salivary glands.Symptoms typically occur 16 to 18 days after exposure and resolve after 7 to 10 days.Symptoms are often more severe in adults than in children.About a third of people have mild or no symptoms.Complications may include meningitis (15%), pancreatitis (4%), inflammation of the heart, permanent deafness, and testicular inflammation, which uncommonly results in infertility.Women may develop ovarian swelling, but this does not increase the risk of infertility.

Mumps is highly contagious and spreads rapidly among people living in close quarters.The virus is transmitted by respiratory droplets or direct contact with an infected person.Only humans get and spread the disease.People are infectious from about 7 days before onset of parotid inflammation to about 8 days after.Once an infection has run its course, a person is typically immune for life.Reinfection is possible, but the ensuing infection tends to be mild.Diagnosis is usually suspected due to parotid swelling and can be confirmed by isolating the virus on a swab of the parotid duct.Testing for IgM antibodies in the blood is simple and may be useful; however, it can be falsely negative in those who have been immunized.
