Haemophilus influenzae Sepsis and Placental Abruption in an Unvaccinated Immigrant.

Background: Haemophilus influenzae infections have declined dramatically in the United States since implementation of the conjugate vaccine. However, in countries where widespread immunization is not routine, H influenzae remains a significant cause of morbidity and mortality. We report a case of a previously unvaccinated immigrant with confirmed H influenzae sepsis and placental abruption leading to spontaneous abortion.
