Very brief blog. On March 6, 2021, NYT published an excellent article with first-class graphics on the spread of COVID variants in the US. Multiple references to work performed under a federal contract by HELIX. In addition, the article references an online 24 page PDF (Feb 2021) from the Johns Hopkins Center for Health Security.
