What should you know about measles deadly?

Measles is a highly contagious viral infection. It often begins with fever, cough, runny nose and sore eyes, followed by a rash. Most people recover, but the infection can place strain on the lungs and immune system. Complications may include pneumonia, ear infection, severe dehydration or inflammation affecting the brain. Babies, pregnant people and those with weakened immunity need especially prompt clinical advice.

A rash or fever does not prove measles, and measles is not diagnosed from danger level alone. A clinician uses the history and examination, including possible exposure and vaccination status.

If measles is possible, call a [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) service before visiting. Describe the fever, cough, rash, breathing and fluid intake, and mention any vulnerable household members. Rest and offer frequent fluids if the person can drink. Follow professional advice about fever relief and isolation. Avoid work, school, childcare and crowded places while contagiousness is being assessed.

Review protection for close contacts through [MMR Vaccination](/treatments/preventive-care-and-vaccination/mmr-vaccination/). Vaccination decisions after an exposure can be time-sensitive, so contact a healthcare service rather than waiting for symptoms.

Call emergency services for severe breathing difficulty, a seizure, collapse, confusion, marked drowsiness, a stiff neck, inability to drink or signs of severe dehydration. Seek same-day advice for worsening [Fever](/symptoms/fever/), persistent vomiting or a child who is becoming less responsive. More context is available in [Measles](/conditions/measles/) and [Swollen Glands](/symptoms/swollen-glands/).

Ask which symptoms require emergency care, how to protect a baby or pregnant household member, whether testing is needed, and when normal activities can safely resume.
