What are the chances of having cmv infections in consecutive pregnancies?

Very low: CMV infection that affects a pregnancy and causes complications is usually a result of a first infection. Because immunity generally results after an infection, the likelihood of having complications occur again are very rare.

Virtually nil: Primary CMV infection happens only once, though the virus lives in the white blood cells of the person for the rest of her/his life and may become active and cause disease if the person is immunosuppressed.
