Measles information: understanding reliable guidance

Measles is a contagious viral infection that can begin with fever, cough, runny nose, or red eyes before a rash appears. A person with these symptoms may have another illness, so symptoms alone cannot confirm measles. The practical concern is avoiding exposure while arranging assessment. See [Measles](/conditions/measles/) and [Fever](/symptoms/fever/) for related explanations.

If you have had contact with measles or develop a compatible illness, phone a [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) service before attending. Describe the exposure, symptoms, vaccination history, pregnancy status, and any immune-suppressing treatment. Keep distance from others while waiting for advice and avoid shared indoor spaces when possible. Ask about [MMR Vaccination](/treatments/preventive-care-and-vaccination/mmr-vaccination/) if your record is incomplete or uncertain.

Seek prompt medical advice for fever with a new spreading rash, cough, red eyes, or a known exposure. Urgent help is needed for difficult breathing, confusion, severe weakness, dehydration, or a child who is hard to wake. Call before arrival so the team can reduce contact with other patients. Swollen glands have several possible causes; more detail is available under [Swollen Glands](/symptoms/swollen-glands/).

Ask how the symptoms fit measles, whether testing or monitoring is needed, whether your vaccination record is sufficient, and how to protect household members.
