During the initial wave of the pandemic, 71% of the novel coronaviruses identified in patients in Houston had this mutation. When the second wave of the outbreak hit Houston during the summer, this variant had leaped to 99.9% prevalence. This mirrors a trend observed around the world. A study published in July based on more than 28,000 genome sequences found that variants carrying the D614G mutation became the globally dominant form of SARS-CoV-2 in about a month. SARS-CoV-2 is the coronavirus that causes COVID-19.University of Texas at Austin – https://medicalxpress.com/news/2020-10-coronavirus-mutation-contagious.html — More information: Molecular Architecture of Early Dissemination and Massive Second Wave of the SARS-CoV-2 Virus in a Major Metropolitan Area, mBIO, DOI: 10.1128/mBio.02707-20 , mbio.asm.org/content/11/6/e02707-20
Kind of spooky if you ask me.
