A new highly mutated COVID-19 variant BA.2.86, sometimes called "Pirola," has recently been detected in various regions, raising concerns among scientists and health authorities. According to Today!, the variant has been identified in several countries, including the United States, Canada, Denmark, Sweden, Portugal, Israel, the United Kingdom, South Africa, and France.
Both the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) are closely monitoring this new variant, which first emerged in late July.
As the NBC Boston report indicates, BA.2.86 appears to have descended from the omicron BA.2 sublineage that triggered virus surges in early 2022. Despite the limited number of identified infections, the simultaneous appearance of the variant in multiple locations, and its considerable genetic differences with previous omicron subvariants, warrant thorough investigation by health officials.
At this stage, it remains unclear whether BA.2.86 poses a more significant threat compared to other coronavirus variants.
Dr. Andrew Pekosz, a virologist at Johns Hopkins University, told Today! that it is too early to determine the transmissibility and severity of this new variant. The CDC, in its risk assessment of BA.2.86, stated that no evidence suggests this variant causes more severe illness. However, data could change as more scientific information becomes available.
