Health Information For Parents
Rubella — commonly known as German measles or 3-day measles — is an infection that mostly affects the skin and lymph nodes. It is caused by the rubella virus (not the same virus that causes measles).
Rubella spreads when people breathe in virus-infected fluid, such as the droplets sprayed into the air when a person with rubella sneezes or coughs, or share food or drink with someone who’s infected. It also can pass through a pregnant woman’s bloodstream to infect her unborn child.
It’s a generally mild disease in children; the primary medical danger of rubella is the infection of pregnant women because it can cause congenital rubella syndrome in developing babies.
Before a vaccine against rubella became available in 1969, rubella epidemics happened every 6-9 years, usually among kids 5 to 9 years old, along with many cases of congenital rubella. Thanks to immunization, there are far fewer cases of rubella and congenital rubella.
Most rubella infections today appear in young, non-immunized adults rather than in kids. In fact, experts estimate that 10% of young adults are currently susceptible to rubella, which could pose a danger to any children they might have someday.
Rubella infection may begin with 1-2 days of mild fever (99-100°F, 37.2–37.8°C) and swollen, tender lymph nodes, usually in the back of the neck or behind the ears. A rash then begins on the face and spreads downward. As it spreads, it usually clears on the face.
The rubella rash is often the first sign of illness that a parent notices. It can look like many other viral rashes, appearing as either pink or light red spots, which may merge to form evenly colored patches. The rash can itch and lasts up to 3 days. As the rash clears, the affected skin might shed in very fine flakes.
Other symptoms of rubella (these are more common in teens and adults) can include headache, loss of appetite, mild conjunctivitis (inflammation of the lining of the eyelids and eyeballs), a stuffy or runny nose, swollen lymph nodes in other parts of the body, and pain and swelling in the joints (especially in young women). Many people with rubella have few or no symptoms.
Rubella in a pregnant woman can cause congenital rubella syndrome, with potentially devastating consequences for the developing fetus. Children who are infected with rubella before birth are at risk for growth problems; intellectual disability; defects of the heart and eyes; deafness; and liver, spleen, and bone marrow problems.
The rubella virus passes from person to person through tiny drops of fluid from the nose and throat through sneezing and coughing. People who have rubella are most contagious from 1 week before to 1 week after the rash appears. Someone who is infected but has no symptoms can still spread the virus.
Infants who have congenital rubella syndrome can shed the virus in urine and fluid from the nose and throat for a year or more and may pass the virus to people who have not been immunized.
Rubella can be prevented by the rubella vaccine. Widespread immunization against rubella is critical to controlling the spread of the disease, thereby preventing birth defects caused by congenital rubella syndrome.
The vaccine is usually given to children at 12–15 months of age as part of the scheduled measles-mumps-rubella (MMR) immunization. A second dose of MMR usually is given at 4–6 years of age. As with all immunization schedules, there are important exceptions and special circumstances. For example, if your child will be traveling outside the United States, the vaccine can be given as early as 6 months of age. Talk to your child’s doctor to see when the vaccine is needed.
The rubella vaccine should not be given to pregnant women or to a woman who may become pregnant within 1 month of receiving the vaccine. If you are thinking about becoming pregnant, make sure that you’re immune to rubella through a blood test or proof of immunization. If you’re not immune, you should receive the vaccine at least 1 month before you become pregnant.
Pregnant women who are not immune should avoid anyone who has the illness and should be vaccinated after delivery so that they will be immune during any future pregnancies.
The incubation period for rubella is 14–23 days, with an average incubation period of 16–18 days. This means that it can take 2–3 weeks for a child to get rubella after being exposed to someone with the disease.
The rubella rash usually lasts 3 days. Lymph nodes may remain swollen for a week or more, and joint pain can last for more than 2 weeks. Children who have rubella usually recover within 1 week, but adults may take longer.
Rubella cannot be treated with antibiotics because they do not work against viral infections. Unless there are complications, rubella will get better on its own.
Any pregnant woman who has been exposed to rubella should contact her obstetrician immediately.
Rubella usually is mild in kids, who often can be cared for at home. Monitor your child’s temperature and call the doctor if the fever climbs too high.
To ease minor discomfort, you can give your child acetaminophen or ibuprofen. Remember, you should never give aspirin to a child who has a viral illness, as its use in such cases has been associated with the development of Reye syndrome.
Call your doctor if your child appears to be getting sicker than the mild course of symptoms described above.
Encephalitis is a rare brain inflammation caused by a virus. The best way to avoid encephalitis is to prevent the illnesses that may lead to it.
If you’re old enough to read this, you’ve probably had most of your shots. But even bigger kids may need a shot once in a while. Find out more about them in this article for kids.
Measles is best known for the skin rash it causes. Although rare, outbreaks can happen. Getting your kids fully vaccinated is the best way to protect them from this disease.
Missing out on shots puts you at more serious risk than you might think. That one little “ouch” moment protects you from some major health problems.
