What should you know about mumps dangerous?

Mumps commonly causes painful swelling near the jaw and may settle with supportive care, but inflammation can affect other parts of the body. Possible concerns include meningitis or encephalitis, inflammation of the pancreas, hearing problems, and painful swelling of the testicles. Symptoms vary, and a person with facial swelling may have another condition; a [Mumps](/conditions/mumps/) assessment is needed for a clear diagnosis.

Risk can be more concerning for people with reduced immunity, during pregnancy, or when severe symptoms are present. Vaccination helps prevent mumps but does not replace assessment of active illness.

Rest, drink fluids, avoid close contact, and do not share items that touch the mouth. Call a clinic before attending if mumps is possible, then arrange a [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) for advice. Keep a note of symptom onset, exposure, vaccination history, and any new pain, vomiting, rash, or hearing change.

Seek emergency help for severe headache, stiff neck, confusion, seizure, fainting, breathing difficulty, repeated vomiting, severe abdominal pain, sudden testicular pain or swelling, or a sudden change in hearing. Contact a clinician promptly for persistent [Fever](/symptoms/fever/), worsening [Swollen Glands](/symptoms/swollen-glands/), inability to drink, or reduced urine.

Ask which symptoms require emergency care, whether testing or monitoring is needed, how long to avoid close contact, and whether family members should review their [MMR Vaccination](/treatments/preventive-care-and-vaccination/mmr-vaccination/) status.
