Also known as: Epidemic Parotitis (Mumps)
Mumps is a contagious viral infection best known for causing painful swelling of the salivary glands (parotitis). It is preventable through the MMR vaccine and is usually self-limiting, though complications can occur.
Mumps is caused by a paramyxovirus and spreads through respiratory droplets and direct contact with saliva. Before the vaccine era, it was one of the most common childhood infections. The incubation period ranges from 12-25 days (average 16-18 days).
The hallmark symptom is bilateral parotid gland swelling, giving the face a characteristic 'chipmunk cheek' appearance. However, up to 30% of infections may be asymptomatic, and some present with only non-specific respiratory symptoms.
Despite high vaccination rates, mumps outbreaks continue to occur, particularly in young adults in close-contact settings such as college dormitories. This may be due to waning vaccine immunity over time.
Complications are uncommon but can include orchitis (testicular inflammation) in post-pubertal males, oophoritis in females, pancreatitis, meningitis, and sensorineural hearing loss.
People with Mumps often experience the following symptoms.
Tender swelling of one or both parotid glands, typically developing over 1-3 days. The swelling may cause pain with chewing and gives the jaw a puffy appearance. It usually resolves within 7-10 days.
Low-grade to moderate fever (38-39.5°C) and general unwellness typically accompany the gland swelling. Fever may precede parotitis by 1-2 days.
Painful testicular swelling occurring in 15-30% of post-pubertal males with mumps, usually 4-8 days after parotitis onset. It is usually unilateral.
Headache and muscle aches are common prodromal and concurrent symptoms. Severe headache with neck stiffness may suggest meningeal involvement.
Certain factors may increase your likelihood of developing Mumps.
Common approaches to managing mumps. Always consult a healthcare provider for personalized treatment.
No specific antiviral therapy exists. Treatment includes rest, adequate hydration, and a soft diet to minimize pain from chewing.
Acetaminophen or ibuprofen for pain and fever. Warm or cold compresses on swollen glands may provide comfort.
Bed rest, scrotal support, ice packs, and anti-inflammatory medications for testicular swelling and pain.
Patients should be isolated for 5 days from parotitis onset to reduce transmission risk. Avoid school, work, and communal settings.
Clinical diagnosis based on parotid swelling with compatible symptoms. Laboratory confirmation involves buccal swab for RT-PCR or viral culture, and mumps-specific IgM serology. Elevated serum amylase supports parotitis.
See a doctor if you develop severe headache with stiff neck (possible meningitis), abdominal pain, testicular swelling, or hearing changes alongside parotitis symptoms.
Steps that may help reduce the risk of developing or worsening mumps.
MMR vaccine (2-dose series in childhood)
A third dose of MMR may be recommended during outbreaks
Avoid sharing eating utensils and drinking glasses
Isolate infected individuals for 5 days after parotitis onset
If left untreated or poorly managed, mumps may lead to:
Orchitis from mumps may cause testicular atrophy in some cases, but complete infertility is rare. Even when bilateral, most men retain fertility.
Yes, though it is less common and typically milder. Vaccine immunity may wane over time, which is why outbreaks occasionally occur in vaccinated populations.
Most people recover within about 2 weeks. Parotid swelling typically resolves within 7-10 days. Complications may extend the illness duration.
