Rubella

Rubella is a contagious viral infection that often causes a rash and swollen glands and needs particular care around pregnancy.

It is also called German measles. Illness is often mild, but infection during pregnancy can harm a developing baby, so avoiding exposure and obtaining prompt advice are especially important.

A fine pink or red rash can begin on the face and move to the body. Swollen glands, particularly around the head and neck, are a very common presentation of rubella. Fever, headache, tiredness, sore throat and a runny nose can occur before or with the rash.

Adults may also experience aching or painful joints. Some people have few symptoms, which is why a new rash or relevant contact should be discussed with a clinician, especially during pregnancy.

Rubella spreads through respiratory droplets when an infected person coughs, sneezes or talks closely with others. It can pass between people before the rash is recognised. Close contact in households, classrooms and shared indoor settings can increase opportunities for spread.

Early symptoms may resemble a mild cold before the rash appears. The rash and general symptoms then settle as the immune system clears the infection. Joint discomfort can last longer than the rash in some adults. A clinician can advise when it is appropriate to return to work, school or childcare.

People who have not received recommended rubella-containing vaccination, or whose vaccination history is uncertain, may be more vulnerable. Anyone who is pregnant and develops a rash, feels unwell after contact with rubella, or learns of a possible exposure should contact their maternity team or clinician promptly.

Because several illnesses can cause a rash, a clinician will ask about symptoms, recent travel, contacts and vaccination history. Blood or swab tests may be used to confirm rubella and help public-health teams reduce further spread. Do not rely on the appearance of a rash alone to identify the cause.

There is no routine antiviral treatment for rubella. Rest, fluids and measures recommended by a clinician or pharmacist for fever or discomfort can help. Keep away from close contact with pregnant people while you may be infectious, and follow the clinician’s advice about isolation.

Seek urgent medical care for trouble breathing, confusion, a severe headache with a stiff neck, or a person who is becoming rapidly more unwell. These symptoms need assessment regardless of the suspected cause.

Use tissues for coughs and sneezes, dispose of them promptly and wash hands often. Avoid sharing drinks, cutlery and towels. Tell the clinic about a suspected rash illness before you arrive so they can advise on the safest way to be seen.

Rubella during pregnancy can affect the developing baby, particularly when infection occurs early in pregnancy. This is why prompt assessment matters after a possible exposure or rash. Your maternity team can explain what tests or follow-up are appropriate for your own circumstances.

Vaccination is the main way to prevent rubella. Check your immunisation record if you are unsure whether you have received the recommended doses. If you are planning a pregnancy, discuss your immunity and the timing of any needed vaccination with a clinician.

A GP can assess a rash illness, arrange testing and advise on reducing spread. Pregnant people should contact their maternity team as well as their usual clinician after a possible exposure. Emergency care is appropriate for severe symptoms such as breathing difficulty or reduced consciousness.
