It introduced concepts such as "cough etiquette", "early, targeted, and layered nonpharmaceutical interventions (NPIs)", "hand hygiene", "nonpharmaceutical intervention (NPI)", and "social distancing".$^{:70}$ In the report's introduction, a chart illustrates how expanding "medical surge capacity", "reducing the anticipated demand for services", and "limiting disease transmission" can delay a "rapid upswing of cases" and lower the "epidemic peak".$^{:17}$ This would "allow a better match between the number of ill persons requiring hospitalization and the nation's capacity to provide medical care for such people."$^{:18}$ This chart was shared on social media in March 2020 during the COVID-19 pandemic.

## 2010s
