Mumps: Symptoms, Causes, and Treatment

Mumps is a viral infection that primarily affects the salivary glands, causing swelling and pain. It spreads through saliva or respiratory droplets. While many cases are mild, serious complications can occur, especially in adults. Vaccination is the best prevention. Most people recover fully with rest and supportive care, but medical attention is crucial for severe cases.

In plain words

Mumps is a viral infection that causes swelling in the salivary glands near the ears. It spreads through saliva or when an infected person coughs or sneezes. Many cases are mild, but serious problems can happen, especially in adults. The best way to prevent mumps is by getting vaccinated. Most people recover fully with rest and care, but severe cases need medical help.

What is Mumps: Symptoms, Causes, and Treatment?

Mumps is a viral infection that primarily affects the salivary glands, causing swelling and pain. It spreads through saliva or respiratory droplets.

Most people recover fully with rest and supportive care, but medical attention is crucial for severe cases.

Symptoms

Early symptoms

  • Fever: Often mild, lasting 1-3 days. May precede other symptoms. (2) (4)
  • Headache: Common early symptom, often accompanied by muscle aches. (2) (4)
  • Muscle aches: Generalized body aches, similar to flu-like symptoms. (2)
  • Fatigue: Feeling tired or lacking energy, often early in the illness. (2) (4)
  • Loss of appetite: Reduced desire to eat, often due to discomfort. (2)
  • Swollen salivary glands: Hallmark symptom, causing puffy cheeks and jaw pain. (2) (4)

Serious or emergency symptoms

  • Severe headache with stiff neck: May indicate meningitis, a serious complication. Seek emergency care immediately. (3)
  • Testicular pain or swelling: Sign of orchitis, a complication affecting males. Consult a doctor urgently. (3)
  • Severe abdominal pain: May signal pancreatitis, a rare but serious complication. Get medical attention right away. (3)
  • Hearing loss: Can occur due to inflammation and requires prompt evaluation. Seek urgent medical care. (3)

Causes

Primary causes

  • Mumps virus: Caused by the rubulavirus, part of the paramyxovirus family. (5)
  • Spread through saliva or respiratory droplets: Transmitted when an infected person coughs, sneezes, or shares utensils. (5)
  • Close-contact environments: High-risk settings include schools, dorms, and sports teams. (5)

Risk factors

Unvaccinated individuals

Highest risk group for contracting mumps. (6) (7)

Incomplete vaccination

One dose of MMR vaccine provides less protection than two doses. (7) (8)

College students or healthcare workers

Increased exposure risk due to close contact settings. (8)

International travelers

Higher risk in regions with lower vaccination rates. (8)

Diagnosis

Doctors typically diagnose mumps based on swollen salivary glands and fever, especially during an outbreak. Laboratory confirmation involves PCR testing of saliva or a blood test detecting mumps-specific antibodies. Because other viruses can cause similar swelling, testing helps distinguish mumps from parainfluenza or Epstein-Barr virus. Local health departments may require reporting suspected cases to track potential outbreaks.

Physical exam

To identify swollen salivary glands and other symptoms. (1)

PCR testing of saliva

Laboratory confirmation of the mumps virus. (1)

Blood test for antibodies

Detects mumps-specific antibodies in the blood. (1)

Treatment

Medication options

Pain and fever reducers

Relieves fever and discomfort from swollen glands. (1)

Lifestyle and self-care

  • Rest: Adequate rest helps the body recover from infection. (4) (5)
  • Hydration: Drink plenty of fluids to prevent dehydration. (4) (5)
  • Soft foods: Eat easy-to-chew foods to reduce discomfort. (4)
  • Isolation: Stay home for 5 days after swelling starts to prevent spread. (7)

Always discuss dosing and treatment changes with your own prescriber.

Possible complications

  • Orchitis: Testicular inflammation affects about 30% of post-pubertal males. (3)
  • Meningitis: Inflammation of the brain and spinal cord membranes. (3)
  • Hearing loss: Rare but possible complication, often permanent. (3)
  • Pancreatitis: Inflammation of the pancreas, causing severe abdominal pain. (3)

When to see a doctor

Routine follow-up

  • Consult a doctor when you suspect mumps to confirm diagnosis and receive guidance on symptom management. (2) (3)

Seek emergency care

  • Seek immediate care for severe headache with stiff neck, severe abdominal or testicular pain, hearing changes, or high fever unresponsive to medication. (3)

Frequently asked questions

What are the first signs of mumps?

Early symptoms include fever, headache, muscle aches, tiredness, and loss of appetite. Swollen salivary glands typically develop 1-3 days later. (2) (4)

How long does mumps last?

Most people recover within 2 weeks. Symptoms like fever last 1-3 days, while gland swelling subsides within a week. (2) (4)

Can you get mumps more than once?

Reinfection is extremely rare. Natural infection usually confers lifelong immunity. (8) (4)

Is there a cure for mumps?

No cure exists. Treatment focuses on relieving symptoms and preventing complications. (1) (4)

How effective is the mumps vaccine?

Two doses of MMR vaccine are about 88% effective at preventing mumps. (7) (8)
