the world is grappling with the resurgence of COVID-19 as a new and concerning variant, BA.2.86, emerges.
This variant, informally dubbed “Pirola,” has ignited alarm among public health experts due to its substantial spike protein mutations.
According to medical experts, BA.2.86 is a designated variant of Omicron, a variant of the SARS-CoV-2 virus responsible for COVID-19. BA.2.86 stems from BA.2, a previously circulating Omicron subvariant. The variant was first identified in Denmark in late July and made its way to the United States in August. Knowing that cases aren’t linked indicates broader circulation, significantly as COVID-19 surveillance has waned, medical experts asserted.
Dr. Roberts emphasized that ongoing studies would reveal the true nature of Pirola’s threat. The unprecedented number of mutations in Pirola is reminiscent of significant shifts seen in other respiratory viruses, such as the 2009 swine flu. However, he noted that these variants sometimes fade away without causing a significant impact.
