What is mumps, and what are its symptoms?
Mumps (epidemic parotitis) is an acute viral infection caused by the mumps virus (Paramyxoviridae, genus Rubulavirus), characterized by painful inflammation of the parotid glands (salivary glands located in front of and below the ears). A notifiable disease in France since 2012, mumps primarily affects adolescents and adults who are unvaccinated or inadequately vaccinated, for whom complications can be serious. Vaccination remains the only effective prevention. Any neurological complication or orchitis must be evaluated urgently by a doctor.

- Transmission and epidemiology: transmission via respiratory droplets (coughing, sneezing) and contact with saliva — peak contagiousness 2 days before parotid swelling begins and lasting up to 5 days afterward — incubation period 16–18 days (range 12–25 days) — primarily affects children and adolescents, but can affect unimmunized adults — cyclical outbreaks occur in the absence of sufficient vaccination coverage (herd immunity threshold: 92–95%)
- Characteristic symptoms: prodromal phase lasting 1–2 days (moderate fever + malaise + loss of appetite + headache) — parotitis (painful unilateral or bilateral swelling of the parotid glands — characteristic “hamster face”) — pain when chewing and swallowing — Sténon’s ostium (opening of the parotid duct opposite the upper second molar), often erythematous — symptoms peak in 2–3 days, then subside within 7–10 days
- Clinical forms: bilateral parotitis (the most common, 75% of cases) — unilateral forms (25%) — asymptomatic forms (20–40% of infections) — forms without parotid involvement (isolated mumps meningitis or isolated orchitis)
- Diagnosis: clinical in most cases — laboratory confirmation if in doubt: RT-PCR on nasopharyngeal or urine specimen (gold standard) — mumps IgM serology (less sensitive) — Complete blood count (leukopenia + lymphocytosis) + elevated amylase levels (parotid involvement)
- Mandatory reporting (MR): must be reported immediately to the Regional Health Agency (ARS)—enables epidemiological surveillance and the implementation of control measures (verification of vaccination status of contacts)
Complications and warning signs
- Mumps orchitis: the most common complication in pubertal males (20–38% of MNI cases in adult males) — occurs 4–8 days after parotitis — painful testicular inflammation, unilateral in 85% of cases — partial testicular atrophy in 50% of cases if bilateral — risk of infertility if bilateral orchitis — treatment: bed rest + scrotal support + analgesics + NSAIDs + corticosteroids if severe (prescription required)
- Meningitis associated with mumps: 1–10% of cases — the most common neurological complication — severe headache + fever + neck stiffness → lumbar puncture → clear, lymphocytic cerebrospinal fluid (viral meningitis) — generally benign and self-limiting with no sequelae — but requires hospitalization and monitoring
- Hearing loss: a rare (1 in 20,000 cases) but serious complication — unilateral sensorineural hearing loss (cochlear involvement) — often irreversible — should be considered in the presence of any tinnitus or hearing loss during the illness → urgent ENT consultation
- Oophoritis: inflammation of the ovaries in women (5% of cases) — pelvic pain + menstrual irregularities — low risk of infertility — gynecological follow-up recommended
- Peripancreatic inflammation: epigastric pain + vomiting + elevated amylase—generally benign and self-limiting—rest + liquid diet + pain relievers—rule out severe pancreatitis (abdominal ultrasound if in doubt)
Symptomatic treatment and complementary natural therapies
- Symptomatic treatment (the only option available): no specific antiviral treatment — acetaminophen 500–1,000 mg × 3/day for fever and pain — NSAIDs (ibuprofen 400 mg × 3/day in adults) for inflammation of the glands and pain — rest at home during the acute phase — ibuprofen is contraindicated in severe epididymitis (debated risk of reduced fertility) → corticosteroids are preferred
- Appropriate diet: chewing and swallowing are painful — soft, cold foods (yogurt, fruit compotes, purees, smoothies) — avoid acidic foods (citrus fruits, vinegar, acidic sauces) and very salty or spicy foods → may worsen parotid pain — cold beverages to relieve local inflammation
- Local care: cold compresses on swollen parotid glands (15 min several times a day) — reduce inflammation and relieve pain — gentle oral hygiene (gentle brushing + alcohol-free antiseptic mouthwash)
- Propolis: anti-inflammatory properties for the mucous membranes + mild antiviral effects — oral spray to relieve pharyngeal inflammation — as a complementary treatment — well tolerated (check for allergies to bee products)
- Hydration: 2–3 L/day of lukewarm or cold liquids — water + broths + cold herbal teas — compensate for fluid loss due to fever and support the healing of salivary mucous membranes
MMR vaccination, isolation, and immune support
- MMR (measles, mumps, rubella) vaccination: the only effective prevention — live attenuated vaccine — French vaccination schedule: 1st dose at 12 months, 2nd dose at 16–18 months — efficacy against mumps: 78% after 1 dose, 88% after 2 doses (less effective than for measles) — booster shots recommended for adults born after 1980 who received < 2 doses or have no documented vaccination history — women of childbearing age: check vaccination status + serology if in doubt — contraindicated during pregnancy and in immunocompromised individuals
- Isolation: stay at home for at least 5 days after the onset of parotid swelling — notify close contacts and the school — verification of contacts’ vaccination status recommended by the ARS — avoid public places (community settings, public transportation)
- Immune support during recovery: vitamin D3 (1,000–2,000 IU/day) + zinc (10–15 mg/day) + vitamin C (acerola) (500 mg/day) — support immune recovery and mucosal healing — visit our immune defense page
- Echinacea during recovery: short course after full recovery — stimulates macrophages and NK cells — do not use during the acute phase (the immune system is already fighting the virus — avoid any interference without medical advice)
- Medical follow-up recommended: medical evaluation after recovery if bilateral orchitis is present (sperm analysis at a later date) — ENT specialist if unilateral hearing loss is suspected — gynecologist if oophoritis is present — report to the Regional Health Agency (ARS) for an epidemiological investigation — EBV-associated infectious mononucleosis is a differential diagnosis to consider — see our page on infectious mononucleosis
