Can rubella cause birth defects?
Pregnant women who contract rubella are at risk for miscarriage or stillbirth, and their developing babies are at risk for severe birth defects with devastating, lifelong consequences. CRS can affect almost everything in the developing baby’s body. The most common birth defects from CRS can include: Deafness.
What infections can cause congenital birth defects?
Toxoplasmosis, cytomegalovirus (CMV), varicella, rubella, and lymphocytic choriomeningitis virus (LCMV) are among the agents that are recognized to have the potential to cause birth defects in a developing fetus.
Which infectious disease is most linked to birth defects?
Cytomegalovirus (CMV) infection is the most common infection present at birth (i.e., congenital infection) in the United States. 3 Infection with CMV during pregnancy increases the risk that the baby will experience congenital CMV.
What happens if you are not immune to rubella while pregnant?
If a pregnant woman is not immune to rubella and catches it during the first 5 months of pregnancy, she usually passes the disease on to her fetus. If the fetus gets rubella during the first 12 weeks of pregnancy, the baby will likely be born with many problems.
What happens if you get rubella vaccine while pregnant?
There is no evidence that getting the MMR vaccine during pregnancy would increase the chance of birth defects. The MMR vaccine is not recommended during pregnancy because of a very small chance of developing the disease from the weakened virus in the vaccine itself.
Some viruses can directly infect the fetus at specific times during gestation, while some only infect the placenta. Both scenarios can result in severe birth defects or pregnancy loss.
What virus can cause teratogenic effects?
Rubella. Rubella is one of the more teratogenic viruses.
What does rubella rash look like?
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.
What is the life expectancy of a baby with microcephaly?
There is no standard life expectancy for microcephalic babies because outcomes depend on so many factors, and the severity of the condition can range from mild to severe. Babies with mild microcephaly may still meet the same milestones like speaking, sitting and walking as a child without the disorder.
What tests help to screen for birth defects?
Amniocentesis. An amniocentesis is test where the doctor collects a small amount of amniotic fluid from the area surrounding the baby. The fluid is then tested to measure the baby’s protein levels, which might indicate certain birth defects.
Are there any infections that cause birth defects?
Naveed Saleh, MD, MS, is a medical writer and editor covering new treatments and trending health news. Brian Levine, MD, MS, is board-certified in obstetrics and gynecology as well as in reproductive endocrinology and infertility. Infection during pregnancy is a major cause of birth defects.
When does congenital rubella affect a fetus?
The most severe effects of the virus on fetal development occur when the mother contracts rubella between conception and the first trimester. Defects from maternal rubella in the first trimester are included in the term congenital rubella syndrome, but physicians and researchers specifically refer to those defects as rubella embryopathy.
When is a baby born with a birth defect?
A birth defect can be found before birth, at birth, or any time after birth. Most birth defects are found within the first year of life. Most birth defects occur in the first 3 months of pregnancy, when the organs of the baby are forming.
What are some birth defects that can cause preterm birth?
It can cause polyhydramios (extra fluid around the baby in pregnancy), which can increase the risk of preterm birth. It is sometimes associated with other genetic syndromes. Dandy walker malformation, an abnormal development of the posterior fossa (a space in your baby’s skull) and cerebellum (a section of the brain).
