Rising above the mask wars: using nonpharmaceutical interventions to lessen the burden of influenza

The COVID-19 pandemic imparted important lessons, both through its direct impact on society and through the manner in which society's response influenced the trajectory of other diseases. The decrements in the rates of infection and morbidity from influenza during 2020 were significant, which is particularly important for pregnant women. Despite past attempts by public health authorities to encourage nonpharmaceutical interventions for the prevention of influenza, preventive efforts have focused largely on the use of vaccines. The COVID-19 experience has demonstrated that basic nonpharmaceutical interventions can potentially make a difference in lowering the rates of influenza during future outbreaks. In this article, we discuss the prepandemic role of nonpharmaceutical interventions in disease prevention, the outcomes that were seen in the flu season of 2020, and the role obstetricians should play in using nonpharmaceutical interventions in future influenza disease prevention efforts.
