Genome sequencing holds clues about the progression of COVID-19 in New York City and offers hints about where to look next.

Researchers at NYU Langone have sequenced the genetic code of samples from 91 COVID-19 patients in New York City, seeking clues to its origin and evolution in this region.
Early data suggest that the virus has been spreading in the city for two months, before testing started. The findings also indicate the New York City outbreak is mostly from a virus “version” that evolved in Europe.
