Introduction

What is rubella?

Rubella is an acute viral infection. It can cause a rash over your child's body, fever, and swelling of the lymph nodes. It is also known as "German measles."

Rubella is usually a mild illness, but it can cause severe birth defects if a pregnant woman is infected. It is rarely diagnosed in Canada because most people are immunized.

Signs and symptoms

Signs and symptoms of rubella

Child with rubella rash on torso — The name rubella comes from the Latin for "little red". Rubella is also sometimes called "German measles."

Rubella is a mild infection in infants and children. Many children do not show any symptoms at all. The infection can be more severe in teenagers and adults. Signs and symptoms may not show until two or three weeks after the infection is in the body.

Some of the signs and symptoms of rubella include:

slight fever
swollen lymph nodes at the back of the neck and behind the ears
a non-itchy rash that first appears on the face and spreads to the body and limbs
the rash consists of tiny, flat pink spots that become paler when pressed
the rash usually appears after a few days of fever and feeling unwell
joint pain is common in adolescent and adult women
joint pain usually occurs after the rash and may last for a few weeks

Not all cases of this condition look the same and many conditions can look similar. For information about your child's illness, please speak to your child's doctor.

Causes, risk factors and prevalence

Causes of rubella

Microscopic view of rubella virus — Under a microscope, the rubella virus particles look like small spheres.

The rubella virus is spread through the air by infectious droplets when an infected person coughs, sneezes or touches a surface. Your child may contract the virus by inhaling or touching these droplets then touching their face, mouth, eyes or ears.

Risk factors

Your child is more likely to contract the illness if:

your child has not had the MMR vaccination
your child has made international travel without being vaccinated

Prevention

Rubella can be prevented by immunization with the Measles-Mumps-Rubella (MMR) vaccine. In Canada, two MMR vaccines are routinely recommended at 12 and 18 months.

Complications

The most serious complication of rubella occurs when a pregnant woman catches the infection in the first four months of pregnancy. An infected mother can pass the infection to the growing fetus. This can cause miscarriage. Rubella can also damage the developing brain, eyes, ears, heart or other organs. This condition is called congenital rubella syndrome.

Arthritis in the knees, wrists and fingers is common in teenage and adult women. Rarely, rubella can cause low platelet counts, which can result in bleeding. Encephalitis (inflammation of the brain) is another rare complication.

Helping your child

Taking care of your child at home

There is no specific treatment for rubella. You can help your child by trying to make them comfortable. Usually children recover completely from rubella within 10 days of the onset of symptoms. Acetaminophen or ibuprofen can be given for fever.

When to seek medical attention

When to seek medical assistance

If you think your child may have rubella, call your doctor's office immediately. Do not go to the doctor's office right away. There is a risk your child could infect a pregnant woman while in public.

A doctor will examine your child and order a blood test to confirm the diagnosis.
