In the Genome Watch article, it was incorrectly stated that the D614 variant replaced a previously established G614 variant. The sentence has been amended to read ‘Comparison of different regions revealed consistent patterns of the G614 variant replacing a previously established D614 variant.’ The text has been corrected in the HTML and PDF versions of the manuscript. The authors apologize to readers for this error.
