Scientists Find That Pirola Variant of Covid-19 May Be Less Infectious and Deadly Than Feared
The recent panic sparked by the emergence of the BA.2.86, also known as “Pirola,” variant of Covid-19 may have been unnecessary. Initially, experts believed that this variant had mutated in a way that allowed it to easily infect vaccinated individuals and those who had recovered from previous infections. As a result, mask mandates were reinstated in several colleges and businesses, and health officials in New York urged people to wear face coverings during the Labor Day weekend. However, lab tests conducted in the US, Sweden, and China have provided early results suggesting that these fears may have been exaggerated. BA.2.86 may actually be just “another scariant” and not as threatening as initially believed.
The lab tests found that antibodies from vaccinated people and those who had recovered from an infection within the last six months were equally effective at stopping infection from BA.2.86 as they were against other variants. In fact, scientists believe that BA.2.86 may even be less infectious than other currently circulating strains. While it is still too early to pinpoint specific symptoms of BA.2.86, experts suggest that similar Omicron subvariants may display signs such as a runny nose, sore throat, and fatigue.
Chinese researchers discovered that BA.2.86 is approximately 60% less infectious than XBB.1.15, which was the dominant variant in the US until the emergence of EG.5 or Eris. This may explain why BA.2.86 is only being detected at low levels. Furthermore, scientists have warned that while previous infections or vaccinations may not prevent people from catching the virus, they are not more likely to experience severe illness.
Dr. Dan Barouch, a virologist at Beth Israel Deaconess Medical Center in New York, initially doubted the results of the lab tests but became confident in their findings when they were consistently repeated. He described BA.2.86 as a “scariant” and stated that two independent labs have shown that it is not more immune evasive than current variants.
Initial fears about BA.2.86 were driven by its catalog of 35 mutations, which experts believed could help it evade immune defenses and lead to increased infections and severe illness. However, studies in the US, Sweden, and China indicate that the protection offered by vaccines and prior infections still holds against BA.2.86.
Although the studies have certain limitations as they were conducted in a laboratory setting, their results suggest that BA.2.86 is not more infectious or likely to cause severe disease compared to other circulating variants. Experts are cautiously optimistic about these findings, but further research is needed to fully understand the characteristics and potential impacts of BA.2.86.
Overall, these studies provide some reassurance that BA.2.86 may not pose as significant a threat as initially feared. This variant is behind only a small number of infections in the US, with EG.5 being the dominant strain. While Covid-19 hospitalizations in the US are rising, they remain relatively low compared to previous peaks. It is important to continue monitoring the situation and conducting further research to stay ahead of the virus’s evolution.
