The Wall Street Journal informs that Delta accounts for 99% of new Covid-19 cases in the US and roughly 88% of cases globally, according to data from the Centers for Disease Control and Prevention and Nextstrain, an open-source pathogen-tracking service. Virologists expect Delta to outcompete new variants of the SARS-CoV-2 virus, including Lambda and Mu, in their hunt for people susceptible to Covid-19.
The scientists say new case waves would likely be driven by Delta and its sub-variants rather than a new virus lineage. That’s because Delta has evolved to be so transmissible that other variants can’t keep up with the pace of its spread.
