The variant is called EG.5 and is a descendant of Omicron.
The Center for Disease Control and Prevention estimated that EG.5 accounted for roughly 17.3 per cent — or one in six — of new COVID-19 cases in the U.S. in the past two weeks.
That’s because we literally don’t know much. EG.5 has only had 183 sequences submitted to GISAID, and EG.5.1 has had 3400 sequences submitted. This means we only have about 3600 cases confirmed as EG.5, but it’s growth rate since May is crazy fast. 10% of sequences submitted to GISAID by the end of July were for EG.5, compared to 0.02% in May.
Part of the problem is that people have stopped going to the doctor when they can just do a COVID test at home, so we are less able to track individual strains and calculate things like transmission rates. When’s the last time you heard the phrase “contact tracing”?
