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.

Where did the new coronavirus start? Scientists believe the highly contagious virus spreading quickly among humans probably originated with bats. Bats’ amazing immune systems allow them to carry viruses without getting sick themselves. Just as with past viral outbreaks like SARS and MERS, scientists believe bats infected other animals with coronavirus, and those animals then passed it to humans. Listen to learn more about the origin of coronavirus and why scientists believe studying bats could unlock secrets about fighting disease.
