What should you know about rubella virus cause?

The virus enters through the nose or mouth and multiplies in the upper airways before the immune system responds. A person may pass rubella on before recognising the illness, and some infected people have few or no obvious symptoms. When symptoms occur, they can include a mild fever, a fine rash, swollen glands behind the ears or in the neck, and joint pain. A symptom such as fever is not proof of rubella; several infections can cause it. Rubella during pregnancy can harm an unborn baby, so possible exposure should be discussed promptly with a clinician.

If you have been close to someone with suspected rubella, note the date of contact and watch for fever, rash, swollen glands, or joint pain. Phone a GP consultation before arriving if rubella is possible, so the practice can reduce contact with other patients. Avoid close contact with pregnant people until you have received advice. Do not rely on appearance alone to identify the infection; a clinician may consider your symptoms, vaccination history, and testing needs. Check whether MMR vaccination is appropriate for you or your household.

Seek prompt medical advice if you are pregnant and may have been exposed, develop a rash after contact with a suspected case, or become unwell with fever and swollen glands. Call ahead rather than sitting in a waiting room because rubella can spread before the diagnosis is clear. Urgent help is needed for severe breathing difficulty, confusion, fainting, or a rapidly worsening condition; these signs are not specific to rubella but need immediate assessment.

Ask: Could my symptoms fit rubella or another infection? Do I need testing or temporary contact precautions? Is my MMR vaccination record complete? What should I do if someone pregnant has been near me?
