WHO: New Covid-19 Variant PJ.2.1 Mimics Cold and Flu Symptoms

The World Health Organization has warned that symptoms of the new Covid-19 variant PJ.2.1 may resemble those of the common cold and influenza, stating that infections cannot be distinguished by symptoms alone and may require diagnostic testing. The WHO emphasized that testing remains the most accurate method to identify the virus causing an infection, particularly when determining the cause could affect treatment decisions or public-health measures. The organization is closely monitoring the emerging variant amid growing concern over its global spread. Russian infectious disease specialist Elena Malinnikova noted that PJ.2.1 may cause severe sore throat and more prolonged fatigue following recovery compared with some other variants.
