On February 27, a teenager in the Seattle area was diagnosed with Covid-19. Shortly after, researchers at the Seattle Flu Study shared genomic data about his strain of the virus with other researchers on an “open science” site. Armed with that data, researchers involved with a second open science project determined that the teenager’s strain was a direct descendent of a strain of Covid-19 found in an unrelated patient in the Seattle area on January 20. The discovery was a key link in concluding that the virus had been spreading in the Seattle area for weeks.

The way researchers connected those dots highlights the role of open science projects in tracking the evolution of Covid-19 and other diseases. Sharing data and working collaboratively across the web, scientists are quickly analyzing genetic samples, helping to shape the public response. But the rush to interpret the data also creates new risks.
