Does rubella IgG positive have any effect on newborn?

Yes, rubella IgG positive in the mother can have an effect on the newborn, especially if the mother is infected with rubella during pregnancy. Rubella is a contagious viral infection that can cause mild symptoms in children and adults, but can have serious consequences for pregnant women and their unborn babies.

If a pregnant woman is infected with rubella, the virus can cross the placenta and infect the developing fetus. This can lead to a condition called congenital rubella syndrome (CRS), which can cause a range of birth defects, including:

- Heart defects

- Eye problems (such as cataracts)

- Hearing loss

- Mental disabilities

- Growth retardation

The risk of CRS is highest if a woman is infected with rubella in the first trimester of pregnancy, but it can still occur if she is infected later in pregnancy.

Rubella IgG positive means that the mother has antibodies to rubella, which indicates that she has been previously infected with the virus and is now immune. This means that the mother herself is not at risk of developing rubella or CRS, but she could still transmit the virus to her unborn baby if she is infected during pregnancy.

For this reason, it is important for pregnant women to be vaccinated against rubella before they become pregnant. The rubella vaccine is safe and effective in preventing rubella and CRS. If a pregnant woman is not immune to rubella, she should be vaccinated as soon as possible to protect her and her baby from the virus.
