About 1·8 billion people live in fragile contexts worldwide,¹ including 168 million individuals in need of humanitarian assistance. Approximately a quarter of those in fragile contexts are women and girls of reproductive age.² Experience from past epidemics in these settings has shown that discontinuing health- care services deemed unrelated to the epidemic response resulted in more deaths than did the epidemic itself.³ Issues related to sexual and reproductive health are among the leading causes of mortality and morbidity among women of childbearing age, with countries affected by fragility and crisis accounting for 61% of maternal deaths worldwide.⁴
