What should you know about mumps symptoms contagious?

Mumps is caused by a virus that passes through respiratory droplets and saliva. A person may spread it before the most recognisable swelling appears and while symptoms continue. Symptoms can start with tiredness, headache, reduced appetite, muscle aches, or fever, followed by painful swelling near one or both jaw lines. Most people with mumps notice swollen glands or salivary-area tenderness, but symptoms vary. See [Mumps](/conditions/mumps/) and [Fever](/symptoms/fever/) for related information.

Avoid close contact, crowded indoor settings, and shared drinks or utensils while you arrange advice. Cover coughs and sneezes, wash hands, and clean frequently touched surfaces. Rest and drink enough fluid to avoid dehydration. Tell your school, workplace, or household contacts that exposure may have occurred, while protecting your privacy. Contact a [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) service before arriving in person; this allows infection-control advice.

Arrange prompt assessment for fever with jaw or gland swelling, particularly after contact with someone who may have mumps or when vaccination is uncertain. Seek urgent help for breathing or swallowing difficulty, confusion, severe headache with a stiff neck, persistent vomiting, dehydration, or severe testicular pain or swelling. Do not wait for swelling to become severe before asking for advice.

How long might I be contagious? Should household contacts seek advice? Do my symptoms need testing, and when can I safely return to normal activities?
