Fortunately, almost all women in the Netherlands are routinely tested for HIV in the first trimester of their pregnancy. The chance that a pregnant woman is positive for HIV is very small, between 0.04 and 0.08 percent. Even though chances are slim, we can prevent a possible HIV infection in the baby.
Namely, if the mother has HIV, but is adequately treated for the infection, the chance of transmitting HIV to the baby is virtually 0. With proper treatment, the virus can no longer be found in the mother's blood and therefore cannot be transferred. Because we test so well for HIV during pregnancy in the Netherlands, HIV has only been transmitted from mother to child once since 2015.
