How coronavirus mutations can track its spread--and disprove conspiracies
Think of the open-source project Nextstrain.org as an outbreak museum. Labs around the world contribute genetic sequences of viruses collected from patients, and Nextstrain uses that data to paint the evolution of epidemics through global maps and phylogenetic charts, the family trees for viruses.
So far, Nextstrain has crunched nearly 1,500 genomes from the new coronavirus, and the data already show how this virus is mutatingevery 15 days, on averageas the COVID-19 pandemic rages around the world.
As menacing as the word sounds, mutations dont mean the virus is becoming more harmful. Instead, these subtle shifts in the viruss genetic code are helping researchers quickly figure out where its been, as well as dispel myths about its origins.
These mutations are completely benign and useful as a puzzle piece to uncover how the virus is spreading, says Nextstrain cofounder Trevor Bedford, a computational biologist at the Fred Hutchinson Cancer Research Center in Seattle.
