COVID-19 has officially been declared a pandemic, a disease infecting populations throughout the world. The virus spreads easily, and once a few people have it, they can quickly infect many others with whom they have contact. A graph of the infection’s spread shows a sharp peak when the rate of infection is highest. As schools close, more people work from home, and other steps are taken to limit human interaction, scientists expect the rate of infection to slow down and the graph’s curve to flatten. Listen to learn how flattening the curve can help the health care system handle the COVID-19 outbreak, and how past epidemics can help guide today’s decisions about how to respond.
