Acute respiratory infections (ARIs) during pregnancy are associated with poor maternal and fetal outcomes.


Using U.S. Flu Vaccine Effectiveness Network data (2011–2016) from Washington and Michigan, we tested for respiratory viruses among pregnant and non‐pregnant outpatients matched on age, site, and season (n = 191).


Among all participants, detection of human coronaviruses and rhinovirus was common. We also observed differences in virus detection by pregnancy status; human coronaviruses and respiratory syncytial virus (RSV) were detected more frequently among pregnant and non‐pregnant participants, respectively.


The role of respiratory viruses in maternal ARI morbidity should be further characterized to inform implementation of prevention interventions including maternal vaccines.
