Congenital rubella syndrome

If infection occurs 0–days before conception, the infant has a risk of being affected. If the infection occurs 0–weeks after conception, the risk increases to. When rubella infection occurs during early pregnancy, serious consequences–such as miscarriages, stillbirths, and a constellation of severe birth defects in infants–can result.


When a woman is infected with the rubella virus early in pregnancy, she has a chance of passing the virus on to her fetus. This can cause the death of the fetus, or it may cause CRS.

Congenital means the condition is present at birth. Measles infection of the mother during the first trimester of pregnancy is associated with encephalitis, hearing loss, and blindness in the newborn infant, an later, intellectual disabilities. If such an infection does not lead to miscarriage or still birth , the neonate may show severe congenital malformations. The syndrome is characterized by multiple congenital malformations (birth defects) and mental retardation.


When adults and children contract the disease, it is known as rubella , or German measles. It is a highly contagious but generally mild disease, without consequences in most cases. Fetal infection occurs transplacentally during the maternal viremic phase, but the mechanisms by which rubella virus causes fetal damage are poorly understood.

The fetal defects observed in congenital rubella syndrome are likely secondary to vasculitis resulting in tissue necrosis without inflammation. The epidemiology of rubella infection is discussed separately. While rubella virus infection usually causes a mild fever and rash in children and adults, infection during pregnancy, especially during the first trimester, can result in miscarriage, fetal death, stillbirth, or infants with congenital malformations, known as congenital rubella syndrome (CRS). Rubella is an acute, contagious viral infection.


When pregnant women are infected with rubella virus, their babies also are expose which may result in serious complications. Current and Historical Conditions Indexed list of current and historical nationally notifiable conditions. It is primarily characterized by abnormalities of the heart and nervous system, the eyes and the ears.


A baby born affected by rubella is said to have congenital rubella syndrome. Many will have hearing loss, cataracts, other eye conditions, damage to the brain and heart problems that will affect them throughout their life. Some may also have additional needs, such as autism and learning disabilities. OBJECTIVE: To evaluate the impact of rubella vaccination strategies on the rates of acquired rubella and congenital rubella syndrome in the Americas. Pregnant women infected with rubella virus run the risk of harmful effects to their growing fetus.


Babies who are infected can have serious birth defects, called congenital rubella syndrome (CRS). Signs are multiple congenital anomalies that can result in fetal death. Diagnosis is by serology and viral culture.

There is no specific treatment. Prevention is by routine vaccination. Nine states reported seven indigenously acquired cases, four imported cases, and one case with unknown importation status.


The introduction of the MMR vaccine has almost eliminated rubella and congenital rubella syndrome in the UK. As a result, babies were born with congenital rubella syndrome. However, there have been occasional outbreaks the virus.


Once a main cause of congenital abnormalities (1), congenital rubella syndrome (CRS) is now rare in the United States.
