We’re still learning, but it seems that much of the spread of the coronavirus has been caused by what disease trackers call superspreader events.

That’s when a single person infects numerous other people, or when a gathering is linked to numerous cases. There’s no rule for when a cluster of cases is big enough to be called a super spreader event.

But these are not instances of spread within one household. Instead, these are large clusters of cases where infection occurs in settings such as churches, restaurants or bars.

Scientists studying three months of contact tracing data from Hong Kong estimated that 19% of people infected were responsible for 80% of the spread of coronavirus infections.

To prevent superspreader events, we need to better understand them, said Anne Rimoin, an infectious diseases expert at the University of California, Los Angeles.

She has called for detailed contact tracing of the infections around President Donald Trump, including those who attended a Sept. 26 Rose Garden ceremony and indoor White House reception for Supreme Court nominee Judge Amy Coney Barrett.

The timing of the event and the number of people infected suggests the possibility of superspreading, she said.

“Contact tracing is the way you get to the bottom of a superspreader event,” Rimoin said. “That’s how you break chains of transmission.”

Unlike many contact tracing investigations, where it can be difficult to find everybody involved, the White House investigation would have “exquisite records and video about who was where and when,” Rimoin said.

“It’s an opportunity to learn about superspreader events that could save thousands of lives, if not millions of lives, in the long run.”
