What is Rubella?
Rubella (German measles) is a contagious viral illness that is now uncommon due to immunization. It usually causes little more than a mild red rash that spreads from the face to the body. Often there are no symptoms at all. A child may start with a mild fever, swollen glands, and a runny nose 2–3 weeks after contact with the infection. Adults may also have a headache and joint pain.
The main risk of rubella is that it can harm the fetus if a woman contracts the virus in pregnancy, particularly in the early months. Rubella is infectious for about 7 days before the rash develops and for about 5 days afterward.

Clinical context
See your doctor first
Arrange to see your doctor if you suspect that you have rubella. Check when to attend the office, as rubella is highly contagious and you must avoid contact with anyone who may be pregnant.
03 · Act
Seek further medical advice if you develop:
- 1Headache or drowsiness.
- 2Joint pain or sore, red eyes.
- 3Any concern about pregnancy exposure — contact your doctor immediately regardless of symptoms.

Practical steps
Isolate immediately to protect pregnant women
Rubella poses a serious risk to unborn babies. As soon as you suspect rubella, avoid all contact with anyone who might be pregnant — including in waiting rooms. Notify your doctor before attending so arrangements can be made.
- 1Take analgesics.Acetaminophen or ibuprofen will reduce fever and relieve headache and joint pain. For children, use the appropriate formulation for their age.
- 2Drink plenty of fluids.Stay well hydrated to prevent dehydration, especially if fever is present.
- 3Avoid contact with pregnant women.Rubella is infectious before and after the rash. Avoid all contact with pregnant women from the moment you suspect the illness.
- 4Rest.Symptoms are usually mild and resolve within a few days. Rest at home and avoid public spaces until you are no longer infectious (5 days after the rash appears).
Practical technique
Practical technique — checking immunity before pregnancy
What to do if you are planning to conceive
Rubella infection during early pregnancy can cause serious birth defects. Checking immunity before conceiving is a simple and important step.
- Blood test: A simple blood test can confirm whether you are immune to rubella. Ask your GP to arrange this as part of pre-conception care.
- If not immune: You can receive the MMR vaccine before trying to conceive. Wait at least one month after vaccination before becoming pregnant.
- Previous rubella: Even if you believe you have had rubella before, immunity should be confirmed with a blood test — clinical diagnosis is not always reliable.
The MMR vaccine cannot be given during pregnancy. Check and address immunity before conception to protect your future pregnancy.

BarnMD Bottom Line
Rubella is usually mild, but it poses a serious risk during pregnancy. Immunization with the MMR vaccine is the best protection for yourself, your children, and your community.
If you are planning a pregnancy, ask your doctor to confirm your rubella immunity with a blood test.
