Tracking a pandemic: Q&A with a COVID-19 detective

Dr. Trevor Bedford, a computational biologist at Fred Hutchinson Cancer Research Center in Seattle, has followed the virus as it hopped from China to Washington to a cruise ship in California. He tracks the virus on Nextstrain, a public website he co-developed that provides informative and animated maps of viral evolution. (The genetic sequences are pulled from GISAID, an online repository where labs from all over the world post new genomic data.) Bedford is also publicly sharing his work on Twitter.
