Covid-19 Virus Variants Mu and Lambda Unlikely to Supplant Delta – The Wall Street Journal

The Delta variant of the Covid-19 virus appears well placed to preserve its supremacy over brand-new variations such as Lambda and Mu, virologists say.
Delta represents 99% of brand-new Covid-19 cases in the U.S. and approximately 88% of cases worldwide, according to information from the Centers for Disease Control and Prevention and Nextstrain, an open-source pathogen-tracking service. Virologists expect Delta to outcompete new versions of the SARS-CoV-2 virus, including Lambda and Mu, in their hunt for people susceptible to Covid-19.
