  Definition  Rubella isa contagious viral infection best known by its distinctive red rash. It's also called German measles or three-day measles. This infection may cause mild or no symptoms in most people. However, it can cause serious problems for unborn babies whose mothers become infected during pregnancy.  Rubella isn’t the same as measles, but the two illnesses share some signs and symptoms, such as the red rash. Rubella is caused by a different virus than measles, and rubella isn’t as infectious or as severe as measles.  The measles-mumps-rubella (MMR) vaccine is safe and highly effective in preventing rubella. The vaccine provides lifelong protection against rubella.  In many countries, rubella infection is rare or even nonexistent. However, because the vaccine isn’t used everywhere, the virus still causes serious problems for babies whose mothers are infected during pregnancy.

  Symptoms  The signsand symptoms of rubella are often difficult to notice, especially in children. Signs and symptoms generally appear between two and three weeks after exposure to the virus. They usually last about 1 to 5 days and may include:  Mild fever of 102 F (38.9 C) or lower  Headache  Stuffy or runny nose  Red, itchy eyes  Enlarged, tender lymph nodes at the base of the skull, the back of the neck and behind the ears  A fine, pink rash that begins on the face and quickly spreads to the trunk and then the arms and legs, before disappearing in the same order  Aching joints, especially in young women

  The Rash dueto rubella on a child’s back. The area affected is similar to that of measles but the rash is less intensely red.

  Causes  Rubella iscaused by a virus that's passed from person to person. It can spread when an infected person coughs or sneezes. It can also spread by direct contact with infected mucus from the nose and throat. It can also be passed on from pregnant women to their unborn children through the bloodstream.  A person who has been infected with the virus that causes rubella is contagious for about one week before the onset of the rash until about one week after the rash disappears. An infected person can spread the illness before the person realizes he or she has it.  Rubella is rare in many countries because most children are vaccinated against the infection at an early age. In some parts of the world, the virus is still active. This is something to consider before going abroad, especially if you're pregnant.  Once you've had the disease, you're usually permanently immune.

  Complications  Rubella isa mild infection. Some women who have had rubella experience arthritis in the fingers, wrists and knees, which generally lasts for about one month. In rare cases, rubella can cause an ear infection or inflammation of the brain.  However, if you're pregnant when you get rubella, the effect on your unborn child may be severe, and in some cases, fatal. Up to 90% of infants born to mothers who had rubella during the first 12 weeks of pregnancy develop congenital rubella syndrome. This syndrome can cause one or more problems, including:  Growth delays  Cataracts  Deafness  Problems with the development of the heart (congenital heart defects)  Problems with the development of other organs  Problems with mental development and learning  The highest risk to the fetus is during the first trimester, but exposure later in pregnancy also is dangerous.

  Prevention  The rubellavaccine is usually given as a combined measles-mumps-rubella (MMR) vaccine. This vaccine may also include the chickenpox (varicella) vaccine ⸺ MMRV vaccine. Health care providers recommend that children receive the MMR vaccine between 12 and 15 months of age, and again between 4 and 6 years of age — before entering school.  The MMR vaccine prevents rubella and protects against it for life. Getting the vaccine can prevent rubella during future pregnancies.  Babies born to women who have received the vaccine or who are already immune are usually protected from rubella for 6 to 8 months after birth. If a child requires protection from rubella before 12 months of age — for example, for certain foreign travel — the vaccine can be given as early as 6 months of age. But children who are vaccinated early still need to be vaccinated at the recommended ages later.  Providing the MMR vaccine as a combination of recommended vaccines can prevent delays in protection against measle, mumps and rubella and with fewer shots. The combination vaccine is as safe and effective as the vaccines given separately.

  Side effects ofthe vaccine  Most people experience no side effects from the vaccine.  For some people, minor side effects may appear about two weeks after vaccination, but usually occur less often after the second shot. These can include:  Sore arm at the injection site  Fever  Mild rash or redness at the injection site  Very few people experience:

   Temporary jointpain or stiffness, especially in teens and adult women who weren't previously immune to rubella  Swelling of the glands in the cheeks or neck  Seizures that occur with a fever  Low level of cells in the blood that help with clotting (platelets), which can cause unusual bleeding or bruising  Rash all over the body  Serious allergic reaction, very rarely

  Diagnosis  The rubellarash can look like many other viral rashes. So health care providers usually confirm rubella with the help of lab tests. You may have a virus culture or a blood test, which can detect the presence of different types of rubella antibodies in your blood. These antibodies show whether you've had a recent or past infection or a rubella vaccine.

  Treatment  No treatmentshortens the course of rubella infection, and symptoms don't usually need to be treated because they're often mild. However, health care providers usually recommend isolation from others — especially from pregnant women — during the infectious period. Isolate from others as soon as rubella is suspected and until at least seven days after the rash disappears.  Support of an infant born with congenital rubella syndrome varies depending on the extent of the infant's problems. Children who have multiple complications may require early treatment from a team of specialists.
• 13.
  Lifestyle and homeremedies  Simple self-care measures are required when a child or adult is infected with the virus that causes rubella, such as:  Bed rest  Acetaminophen (Tylenol, others) for relief from fever and aches  Use caution when giving aspirin to children or teenagers. Though aspirin is approved for use in children older than age 3, children and teenagers recovering from chickenpox or flu-like symptoms should never take aspirin. This is because aspirin has been linked to Reye's syndrome, a rare but potentially life-threatening condition, in such children. For treatment of fever or pain, consider giving your child infants' or children's over-the-counter fever and pain medications such as acetaminophen (Tylenol, others) or ibuprofen (Advil, Motrin, others) as a safer alternative to aspirin.
