From Fortune:

The highly mutated COVID-19 variant BA.2.86, a close ancestor of the Pirola JN.1, may cause more severe disease than other Omicron variants, according to two recent studies. The studies found that BA.2.86 has traits similar to pre-Omicron strains that were more deadly and infects cells in the lower lung more efficiently. The variant may constitute an elevated health threat compared to previous Omicron sublineages.

Experts say that it is impossible to definitively say if the initial Omicron strain is less severe than earlier variants due to waning immunity. This means that new studies that show Omicron may be evolving into a more severe form are concerning. Some experts say that the new studies need more investigation and could be a cause for alarm.

Concerns are being raised about the possibility of COVID recombining with another coronavirus in animals, then transitioning back over to humans—providing another twist to the pandemic’s narrative. Some experts are concerned that animals, such as white-tailed deer, could provide an environment for COVID to mutate and potentially combine with other, more deadly coronaviruses.

Overall, concerns are growing about the possibility of further coronavirus evolution in animals and its impact on humans. With the threat of COVID recombining with more deadly coronaviruses if given the opportunity, experts recommend increased vigilance in watching out for potential future developments related to the virus.
