What should you know about three-day measles?

Rubella can begin with mild cold-like symptoms, followed by a pink or red rash that may spread across the face and body. Tender swollen glands, especially behind the ears or at the back of the neck, can occur. The illness may be mild, so appearance alone cannot confirm the cause. Rubella is different from measles, although the rashes can look similar. Infection during pregnancy can harm an unborn baby, making prompt medical advice especially important.

Avoid close contact with pregnant people and others who may be unprotected until a clinician advises that you are no longer infectious. Call ahead before attending a clinic if you have a rash or fever, so the service can reduce exposure to others. Rest, drink fluids, and use symptom relief only as advised for your age and health. A GP consultation can help distinguish rubella from measles and other rash illnesses. MMR vaccination helps prevent rubella.

Arrange prompt assessment for a new rash with fever, particularly after travel or contact with an illness. Seek urgent help for breathing difficulty, severe headache, unusual drowsiness, dehydration, or a rapidly worsening condition. Anyone who is pregnant or may be pregnant should contact a clinician promptly after possible exposure, even if symptoms are mild.

Ask whether testing is needed, how long to stay away from others, whether your vaccination history changes the advice, and what to do after exposure during pregnancy.
