As we go to press—at the end of March 2020—with this issue of *La Santé en action* dedicated to perinatal care, our quarterly journal on prevention, education, and health promotion, the country is being hit very hard by the coronavirus (COVID-19) pandemic. Our thoughts are with those who have been affected, and we extend our condolences to the families of the victims. We stand with healthcare professionals, all other professionals, and citizens who are on the front lines. Santé publique France is mobilized to provide its expertise to public authorities and to fulfill its mission of surveillance, alert, monitoring, expertise, and information in the service of professionals and all citizens. As part of its missions, our agency is contributing to the unprecedented mobilization currently underway in the country.
