When compared with nonpregnant women, season influenza poses higher risks of hospitalization on pregnant women in all trimesters, a new study found. Researchers joined individual-level administrative datasets and active surveillance data to estimate influenza-association hospitalization and outpatient visit rates by pregnancy, postpartum, and trimester status. They found:
- During 2012‒2015, 46 (17.5%) of 260 influenza-confirmed acute respiratory hospitalizations and 13 (4.4%) of 294 influenza-confirmed outpatient visits were among pregnant and postpartum women.
- Pregnant and postpartum women experienced higher rates of influenza hospitalization compared with nonpregnant women overall and by trimester.
- Hospitalization rates varied by influenza type and ethnicity among pregnant women.
