What should you know about German measles virus?

Rubella virus passes mainly through respiratory droplets when an infected person coughs, sneezes, or speaks. Infection can be mild or unnoticed, yet transmission can still occur around the time symptoms develop. When symptoms appear, a fine rash, low fever, tiredness, sore throat, and swollen glands may be present; joint pain is more common in adults.

Rubella is not the same virus as measles. Its greatest concern is infection during pregnancy, because it can affect the developing baby. This is why suspected exposure should be discussed promptly with a healthcare professional.

If rubella is possible, limit close contact, especially with pregnant people, and call a GP practice before going in. Cover coughs and sneezes, wash hands, and avoid sharing personal items. Keep track of the rash, fever, contacts, and vaccination history for the clinician.

MMR vaccination helps prevent rubella infection. Ask a vaccination service to review your protection, particularly if records are incomplete or you work closely with children or vulnerable people.

Arrange prompt medical advice for a new rash with fever or after known contact with rubella. Contact a clinician urgently after exposure during pregnancy or when pregnancy is possible. Emergency care is needed for breathing problems, fainting, confusion, severe dehydration, or a rapidly worsening illness.

Ask how rubella is confirmed, how long to avoid close contact, whether testing is needed, and whether you or household members should discuss MMR vaccination.
