A recent outbreak of coronavirus infections at the White House is highlighting how superspreading events can quickly infect large numbers of people.

The symptoms of COVID-19 often do not appear for several days in a newly infected person, but it is during this pre-symptomatic period that the person is most contagious. Because of this, public health experts are finding coronavirus especially hard to contain. Listen to an epidemiology professor describe the challenges of containing a virus that spreads silently, and which strategies have been proven to work best.
