Is a woman’s pregnancy at risk if she contracts West Nile virus?
Many women infected with West Nile virus during pregnancy will not have any signs of illness, while some may develop West Nile virus fever or West Nile virus neurologic disease. There is limited evidence to suggest that West Nile virus can be transmitted to a fetus when the mother is infected during pregnancy, regardless of whether the mother has symptoms of illness. There is not enough information to determine if West Nile virus infection during pregnancy results in adverse birth outcomes.
