How ‘Superspreading’ Events Drive Most COVID-19 Spread
As few as 10 percent of infected people may drive a whopping 80 percent of cases, in specific types of situations

As scientists have learned more about COVID-19, it has become clear that so-called superspreader incidents—in which one person infects a disproportionate number of other individuals—have played an oversized role in the transmission of the virus that causes the disease. The Boston conference and the funeral in Georgia were among several superspreader events that played “a notable role in the early U.S. spread of COVID-19,” according to a report by Anne Schuchat, principal deputy director of the Centers for Disease Control and Prevention. In fact, research on actual cases, as well as models of the pandemic, indicate that between 10 and 20 percent of infected people are responsible for 80 percent of the coronavirus’s spread.

These numbers mean that preventing superspreader events could go a long way toward stopping COVID-19, says Samuel Scarpino, a network scientist who studies infectious disease at Northeastern University. Scientists have identified factors that catalyze such events, including large crowd sizes, close contact between people and confined spaces with poor ventilation. Current evidence suggests that it is mostly circumstances such as these, rather than the biology of specific individuals, that sets the stage for extreme spreading of the novel coronavirus.

1. Yet, one person is more responsible for thousands of

infections and deaths than the 10% of individuals at super spreader events. He is the super spreader of Covid.
