The COVID-19 Pandemic and Its Lessons

Public health, with its goals of preventing disease, promoting health and prolonging life, comprises a complex system affecting almost every facet of life, both in health and disease.

Public health rests on both epidemiology and emergency preparedness. In an outbreak of an infectious disease, it is the science of epidemiology that defines the response, while emergency preparedness planning provides its framework.

What Happened in the USA During the Pandemic?

In 2019, the US had scored the highest on the Global Health Security Index of Pandemic Preparedness. So how could a country that outranked 194 other countries suffer the third highest age-adjusted mortality among similarly ranked countries during the COVID pandemic?
