AI Summary Overview
What is Mumps?
Mumps is an acute viral infection caused by the mumps virus. It commonly affects the parotid glands, which are large salivary glands located in front of and below each ear. Inflammation of these glands is called parotitis. It can cause painful swelling on one or both sides of the face, producing the characteristic puffy cheeks and swollen jaw associated with mumps.
The virus spreads mainly through respiratory droplets and direct contact with saliva. Transmission can occur when an infected person coughs, sneezes, talks, kisses someone or shares objects contaminated with saliva.
Symptoms usually develop about 16 - 18 days after exposure, although the incubation period can range from approximately 12 - 25 days. People are most infectious around the onset of parotid swelling, including roughly two days before it appears and five days afterwards.
Although the salivary glands are most commonly affected, mumps can sometimes involve the nervous system, testicles, ovaries, pancreas and other organs. Complications are more common among adolescents and adults than young children.
What are the Types of Mumps?
There is no formal classification of clinical types of mumps. But the presentation of mumps can be different based on the patient's age, immunisation status, affected organs and complications. The presentations below describe different ways the mumps infection may appear rather than separate diseases:
-
Asymptomatic or Subclinical Mumps Some people infected with the mumps virus develop no noticeable symptoms or experience only mild, non-specific symptoms. Since these people may not realise that they are infected, transmission can occur without the characteristic cheek or jaw swelling being recognised.
-
Mumps With Parotitis This is the classic and most recognisable presentation. Inflammation causes swelling and tenderness of one or both parotid glands. The person may also experience fever, headache, muscle aches, tiredness and loss of appetite. Parotid swelling often peaks within a few days and gradually improves over the following week.
-
Mumps Without Parotitis Mumps does not always cause visible swelling of the salivary gland. Some infected people experience only fever, headache, tiredness or respiratory symptoms. Complications such as orchitis, meningitis or pancreatitis can occasionally occur even without obvious parotitis.
-
Breakthrough Mumps Breakthrough mumps refers to an infection occurring in someone who has previously received a mumps-containing vaccine. Vaccination does not provide complete protection for every person. Also, protection against mumps can decrease over time. However, vaccinated people who develop mumps generally have a lower risk of severe symptoms and complications than people without adequate vaccination.
-
Mumps During Pregnancy Pregnant women with mumps are vulnerable to complications that affect their health and the health of the fetus. Even though congenital mumps syndrome is not clearly defined compared to congenital rubella syndrome, it requires immediate medical care.
How Common is Mumps in India?
A reliable national prevalence rate for mumps in India is difficult to establish because reporting, laboratory confirmation and surveillance vary between regions. In March 2024, Kerala reported more than 190 mumps cases in a single outbreak, followed by around 2,500 additional cases after a health alert was issued. Cases were also reported from Maharashtra, Andhra Pradesh, Telangana and other states.
The rise in infections was linked to the prolonged period of communicability, a shift in the age groups affected and the presence of a substantial proportion of subclinical cases, which can contribute to unnoticed transmission.
What are the Stages of Mumps?
Mumps is a disease that undergoes various stages from its onset to its resolution. However, the amount of time taken for each of the stages is not similar between patients.
These stages of mumps are shown in the table below:
| Phase | Features |
| Incubation Period | No symptoms are present while the virus replicates after exposure. This period usually lasts around 16-18 days but can range from about 12-25 days. |
| Early or Prodromal Phase | Fever, headache, muscle aches, tiredness and reduced appetite may appear several days before salivary-gland swelling. |
| Parotitis Phase | One or both parotid glands may become painful and swollen, causing cheek or jaw swelling and discomfort while chewing or swallowing. |
| Recovery Phase | Gland swelling and other symptoms gradually improve. Most uncomplicated cases recover completely within about two weeks. |
Not everyone follows this pattern. Some people have very mild symptoms, no parotid swelling or no noticeable illness at all.
What are the Symptoms of Mumps?
Symptoms of mumps vary and normally occur once the incubation period is over. In some cases, individuals suffer from mumps but do not exhibit any symptoms.
The symptoms of mumps are shown in the following table:
| Early Warning Signs | Severe Stage Symptoms |

Diseases Similar to Mumps
Several conditions can cause swelling around the cheeks, jaw or salivary glands and may be mistaken for mumps. A proper medical assessment is important when symptoms are persistent, severe or do not follow the typical pattern of mumps.
The following table compares mumps with two common conditions that can resemble it:
Mumps Vs. Bacterial Parotitis Vs. Salivary Gland Stones
| Feature | Mumps | Bacterial Parotitis | Salivary Gland Stones |
| How It Happens | Viral infection causes salivary-gland inflammation | Bacteria infect a salivary gland | A stone blocks a salivary duct |
| Location | Usually parotid glands near the ears | Usually one salivary gland | Affected salivary gland or duct |
| Associated Symptoms | Fever, headache, tiredness and jaw swelling | Fever, marked tenderness and sometimes pus from the duct | Pain and swelling, often worse during meals |
| Severity | Usually mild, but complications can occur | Can become serious without treatment | Usually localised unless infection develops |
| Can It Be Reversed? | Usually resolves with supportive care | Usually improves with appropriate antibiotic treatment and drainage when required | May pass or require removal |
What Causes Mumps?
Mumps is caused by infection with the mumps virus. The virus spreads from one person to another rather than developing because of lifestyle or environmental factors.
The main routes of mumps transmission include the following:
-
Respiratory Droplets: An infected person can release virus-containing droplets while coughing, sneezing or talking.
-
Direct Saliva Contact: Kissing or other direct contact with infected saliva can transmit the virus.
-
Shared Items: Cups, bottles, eating utensils and other objects contaminated with saliva can contribute to transmission.
-
Close Contact: Prolonged close contact at home, school, college, work or other shared environments increases exposure.
-
Transmission Before Parotitis: People can transmit the virus before the characteristic cheek or jaw swelling becomes obvious.
The likelihood of transmission increases with close and prolonged contact.
What are the Risk Factors for Mumps?
Anyone without adequate immunity can develop mumps after exposure. Certain circumstances make infection more likely. The main risk factors for mumps include the following:
-
Being unvaccinated against mumps
-
Having an incomplete mumps vaccination
-
Close contact with someone who has mumps
-
Living with an infected household member
-
Sharing cups, bottles or utensils with an infected person
-
Living, studying or working in crowded settings
-
Staying in hostels, dormitories or other congregate environments
-
Exposure during a community outbreak
-
Having immunity that has decreased since the previous vaccination
-
Having certain conditions or treatments that affect immune function
Having one or more risk factors does not mean a person will definitely develop mumps.
What are the Complications of Mumps?
Most people recover fully from mumps. However, complications are more common after puberty and can sometimes occur without parotid swelling.
Complications associated with mumps are given below:
-
Orchitis: Inflammation of one or both testicles, causing pain, swelling and tenderness. Testicular shrinkage can rarely occur.
-
Oophoritis: Inflammation of the ovaries, which may cause pelvic or lower abdominal pain.
-
Mastitis: Inflammation of breast tissue that can occasionally occur in adolescent or adult females.
-
Meningitis: Inflammation of the membranes around the brain and spinal cord, causing headache, neck stiffness, fever or vomiting.
-
Encephalitis: Rare inflammation of the brain that may cause confusion, seizures or altered consciousness.
-
Pancreatitis: Inflammation of the pancreas, causing upper abdominal pain, nausea and vomiting.
-
Hearing Loss: Temporary or permanent hearing impairment can rarely occur.
-
Other Rare Complications: Mumps can occasionally affect organs such as the heart or kidneys.
When Should I See a Healthcare Provider for Mumps?
Medical assessment is appropriate when mumps is suspected, particularly if cheek or jaw swelling occurs after possible exposure.
It is recommended to seek medical attention if you experience:
-
New swelling around one or both cheeks or jaws
-
Fever with salivary-gland swelling
-
Significant pain while chewing or swallowing
-
Symptoms after known exposure to mumps
-
Persistent or worsening symptoms
-
Difficulty maintaining adequate fluid intake
-
New hearing problems
-
Testicular or pelvic pain
Certain symptoms may indicate complications and require more urgent assessment. Seek urgent medical attention for any or multiple of the following:
-
Severe or persistent headache
-
Stiff neck
-
Confusion
-
Seizures
-
Loss of consciousness
-
Severe abdominal pain
-
Severe testicular pain or swelling
-
Breathing difficulty
-
Rapidly worsening illness
Pregnant women with suspected mumps should also contact a doctor for individual assessment.
How is Mumps Diagnosed?
Mumps diagnosis begins with the symptoms, physical findings, vaccination history and possible exposure. Laboratory testing is often useful because other viral and bacterial illnesses can also cause parotid swelling. The common diagnostic measures used to detect mumps are:
-
Medical History
A doctor may ask several questions to assess the likelihood of mumps. These may include:
- When the swelling or other symptoms began
- Whether one or both sides of the face are swollen
- Whether fever, headache or muscle aches are present
- Whether chewing or swallowing is painful
- Whether there has been recent contact with someone who has mumps
- Previous mumps-containing vaccination
- Recent travel
- Exposure to a known outbreak
- Current medical conditions and medicines
This history helps distinguish mumps from other causes of salivary-gland swelling.
-
Physical Examination The doctor examines the face, jaw, neck and mouth. The parotid glands are checked for characteristic swelling and tenderness. Other salivary glands and lymph nodes may also be examined because several conditions can resemble mumps.
-
Buccal Swab RT-PCR A swab taken from inside the cheek near the affected salivary gland can be tested for mumps viral RNA. RT-PCR is the preferred laboratory method for confirming acute mumps when an appropriate sample is collected at the correct time. Samples are generally most useful when collected soon after salivary-gland swelling begins.
-
Blood Tests A blood sample may be tested for mumps IgM antibodies. IgM can support the diagnosis, but it is less reliable than RT-PCR and may be absent in vaccinated people. A negative IgM result, therefore, does not necessarily exclude mumps.
-
Testing for Complications Additional investigations may be required when complications are suspected. Depending on the symptoms, these can include blood tests, urine tests, an ultrasound or cerebrospinal fluid analysis.
Diagnostic Summary Table
| Diagnostic Method | What It Involves | Why It May Be Done |
| Medical History | Reviews symptoms, exposure, vaccination and timing | Assesses whether mumps is clinically likely |
| Physical Examination | Examines parotid and other salivary glands | Identifies characteristic swelling and tenderness |
| Buccal Swab RT-PCR | Tests a cheek swab for viral RNA | Preferred method for laboratory confirmation |
| Mumps IgM Test | Tests blood for an early antibody response | Provides supportive diagnostic evidence |
| Additional Blood Tests | Assesses inflammation or organ function | Used when complications are suspected |
| Ultrasound | Images affected organs such as the testicles | May assess orchitis or alternative diagnoses |
| Cerebrospinal Fluid Testing | Examines fluid around the brain and spinal cord | May be required for suspected meningitis or encephalitis |
How is Mumps Treated and Managed?
There is no routinely recommended antiviral medicine that eliminates the mumps virus. Treatment, therefore, focuses on relieving symptoms, maintaining hydration and nutrition, monitoring for complications and reducing transmission.
Treatment and management approaches of mumps are given below:
-
Supportive Care
Most uncomplicated cases can be managed at home. The following supportive measures may help with recovery:
- Get adequate rest while fever or weakness continues.
- Drink enough fluids to prevent dehydration.
- Choose soft foods when chewing causes pain.
- Avoid very acidic foods if they increase salivary gland discomfort.
- Use warm or cold compresses over the swollen glands according to comfort.
- Use appropriate pain and fever medicines when medically suitable.
Most uncomplicated cases improve within about one to two weeks.
-
Reducing Transmission Someone with mumps should remain away from school, work and close social contact during the infectious period. Once parotid or other salivary gland swelling begins, the person should generally avoid close contact with others for five days. Sharing cups, bottles, utensils and other saliva-contaminated items should also be avoided.
-
Treatment of Orchitis Mumps orchitis is usually treated supportively. Management may include pain relief, rest, scrotal support and cold compresses. Severe pain or diagnostic uncertainty may require hospital assessment.
-
Treatment of Meningitis or Encephalitis Neurological complications like meningitis or encephalitis require hospital assessment. Treatment may include intravenous fluids, neurological monitoring, seizure treatment when needed and intensive supportive care in severe cases.
-
Treatment of Pancreatitis Pancreatitis may require hospital care when pain, vomiting or dehydration is significant. Treatment focuses on fluid replacement, pain management and monitoring.
-
Treatment of Hearing Problems New hearing difficulty should be evaluated. Formal hearing assessment may be required when symptoms persist.
Common Medicines Used to Treat Mumps
There is no specific antiviral medicine routinely used to cure mumps. Medicines are therefore used primarily for symptom relief and complication management.
Commonly used medicines during mumps include:
-
Paracetamol (Acetaminophen): Given to lower the temperature and treat pain associated with swelling of the parotid gland, headaches and muscle aches. This drug is safe for use in children, adolescents and adults. Paracetamol is usually the drug of choice for pain management in paediatric mumps.
-
Ibuprofen: A Non-Steroidal Anti-Inflammatory Drug (NSAID) given to treat fever, pain and inflammation in older children, adolescents and adults. Ibuprofen needs to be taken with caution in patients with gastrointestinal diseases or dehydration.
-
Intravenous Immunoglobulin (IVIG): IVIG is used in rare situations or when the case is serious as a treatment for immunocompromised patients who cannot provide an immune response. This drug is not commonly used in mumps treatment.
-
Intravenous Fluids: The intravenous administration of fluids in hospitalised patients who are unable to take oral fluids due to problems with swallowing, vomiting associated with pancreatitis and confusion from encephalitis.
-
Painkillers for Orchitis: In case of serious orchitis, stronger painkillers can be needed. Apart from the painkillers, the scrotum can be supported, and cold compresses are used.
-
MMR Vaccine (Prevention): The MMR vaccine that is available in India under the brand names like Tresivac (Serum Institute of India) and Morupar (Sanofi) is considered to be the main prevention method against mumps.
Note: All medicines should be used under the supervision of a qualified doctor. Self-medication, particularly in children, is not recommended. Aspirin must not be given to children with viral illnesses.
Living With Mumps: Daily Challenges and Caregiving
Mumps is usually a transient condition. However, the pain, quarantine requirements, potential complications and time off from school or work make this a tough situation for patients and their families to handle.
Some of the common challenges and care points for individuals with mumps are given below:
-
Challenges
- Pain and Discomfort: Swollen salivary glands can cause facial pain and discomfort while chewing.
- Eating Difficulties: Jaw tenderness can make ordinary meals uncomfortable.
- Absence from School or Work: Isolation during the infectious period can interrupt education and employment.
- Fatigue: Fever and viral illness can temporarily reduce energy and normal activity.
-
Patient Well-Being
- Maintain Hydration: Encourage regular fluids throughout the day.
- Choose Comfortable Foods: Soft foods that require little chewing may reduce jaw discomfort.
- Monitor Recovery: Watch for severe headache, testicular pain, neck stiffness, abdominal pain or hearing changes.
-
Expenses
- Consultation and Testing Costs: Medical visits or laboratory confirmation may add to expenses.
- Treatment Costs: Pain relief and treatment of complications can increase medical spending.
- Indirect Costs: School absence, time away from work and caregiver leave can affect families financially.
What is the Prognosis for Mumps?
The prognosis for mumps is good for most people. Uncomplicated mumps generally improves within one to two weeks, and most people recover completely. Parotid swelling usually settles within several days, although fatigue or general discomfort may last somewhat longer.
Certain factors can influence the risk of complications from mumps. These include:
-
Older age, particularly adolescence and adulthood
-
Lack of previous vaccination
-
General health and immune status
-
Development of neurological or other organ complications
-
Severity of dehydration or associated illness
Most people with orchitis, meningitis or pancreatitis also recover with appropriate care. Encephalitis is rare but has a greater potential for lasting neurological effects.
Natural infection usually produces long-lasting immunity. However, reinfection and recurrent parotitis have occasionally been documented, so recurrence should not be described as impossible.
How Can I Prevent Mumps?
Vaccination is the most effective preventive measure against mumps, although no vaccine provides complete protection. Several measures can help reduce mumps and its transmission. These include:
-
Keep recommended mumps-containing vaccinations up to date when medically appropriate.
-
Avoid close contact with someone known to have active mumps.
-
Stay away from school, work and close gatherings for five days after salivary gland swelling begins.
-
Avoid sharing cups, bottles, eating utensils and other items that have been exposed to saliva.
-
Cover coughs and sneezes appropriately.
-
Wash your hands regularly.
-
Clean frequently touched surfaces when someone in the household is ill.
A mumps-containing vaccine can still be useful for people who need protection against future exposure, but vaccination after a particular exposure does not reliably prevent an infection that has already been acquired.
India's routine public childhood schedule currently uses measles-rubella vaccination rather than routine mumps-containing vaccination. Anyway, MMR vaccines are available through private healthcare services.
MMR is a live vaccine and is not generally administered during pregnancy. A person who is not immune can discuss appropriate vaccination before pregnancy or after delivery.
Mumps Treatment Cost in India
Most uncomplicated mumps cases require only outpatient assessment and supportive treatment. Costs rise when laboratory confirmation, specialist assessment or hospital treatment for complications is required.
The following table provides approximate costs for mumps treatment in India:
| Treatment Component | Approximate Cost Range |
| Consultation with a general doctor/paediatrician | ₹300 - ₹2,500 per visit |
| IgM serology test for mumps infection (by ELISA) | ₹500 - ₹1,500 |
| RT-PCR for confirmation of mumps | ₹1,500 - ₹3,000 |
| Painkillers (paracetamol, ibuprofen) | ₹30 to ₹200 per course |
| Consultation with a specialist (if complications are present) | ₹800 - ₹3,000 |
| Ultrasound of the scrotum (if orchitis is present) | ₹500 - ₹2,000 |
| Lumbar puncture and cerebrospinal fluid study (if meningitis is present) | ₹1,000 - ₹5,000 |
| Hospitalisation for complications (orchitis, pancreatitis, meningitis) | ₹15,000 - ₹80,000 per admission |
| Treatment in the ICU for encephalitis or serious complications | ₹50,000 - ₹2,00,000 per admission |
| MMR vaccination (preventive, private clinic) | ₹600 - ₹1,200 per dose |
Note: The above prices are estimates. Actual costs differ between public and private hospitals, cities and doctors. Subsidised and even free treatment is available at public hospitals.
Does Health Insurance Cover Mumps in India?
Yes. Health insurance provides coverage for mumps in India, depending on the terms and conditions of the policy. The expenses covered under the policy may include hospitalisation for mumps-related diseases like orchitis, aseptic meningitis, encephalitis or pancreatitis. The plan may also cover in-patient diagnostic investigation, doctor's fees, medications and pre- and post-hospitalisation expenses as mentioned in the policy documents.
Outpatient doctor consultations, vaccinations, medications and diagnostic tests are covered by the policy if it comes with an OPD cover.
Since mumps is an acute infection rather than a chronic disease, an initial waiting period of 30 days will be applicable. Policy wordings should be reviewed carefully regarding coverage, exclusions, inclusions, room-rent limits, waiting periods and sub-limits before purchasing.
How Much Health Insurance Coverage is Needed for Mumps Treatment?
The amount of health insurance coverage required in case of mumps depends on whether the disease stays uncomplicated or becomes complicated enough to lead to hospitalisation. A regular health insurance plan with a sum insured amount of ₹5 - ₹10 lakh should suffice in cases where hospitalisation is necessary due to some minor complications like orchitis or pancreatitis.
Individuals suffering from more serious complications, like encephalitis, leading to ICU admission or individuals with weakened immune systems who are at greater risk of severe complications, will incur much higher expenses for treatment. ICU stay, neurology services, neurological tests and rehabilitation add up to increased overall expenses.
In such cases, a health insurance plan with a sum insured of ₹15 lakh or above is recommended for individuals who run a higher risk of complications due to age or other medical reasons.
