The Omicron BA.2.86 (Pirola) subvariant, which is the ancestor of JN.1, has emerged as a concern due to rising infection rates. JN.1 has a single mutation in its spike protein, potentially making it more transmissible and able to evade immune reactions. The WHO has designated the current variant as a variant of interest due to substantial changes in the spike protein. Data on severity are limited, but serious pneumonia can occur in individuals with certain medical conditions. Precautions such as wearing masks, avoiding crowds, and preventing infections are advised by the WHO.COVID JN.1 cases rise: Expert shares preventive measures
