Is Coronavirus Mutating Amid its Rapid U.S. Spread?

A new study, currently awaiting peer review and involving more than 5,000 COVID-19 patients in Houston, finds that the virus that causes the disease is accumulating genetic mutations, one of which may have made it more contagious. According to the paper posted this week to the preprint server medRxiv, that mutation, called D614G, was also implicated in an earlier study in the UK in possibly making the virus easier to spread. The Washington Post was among several outlets reporting the findings this week.
