WHO Warns Flu-Like Symptoms May Signal New COVID Variant PJ.2.1

The World Health Organization warns that flu-like symptoms may indicate infection with the new COVID-19 variant PJ.2.1, urging testing because symptoms alone cannot distinguish it from influenza or the common cold. The variant, identified as a SARS-CoV-2 lineage, spreads across countries and presents with overlapping signs such as sore throat, fever, cough, and fatigue. WHO stated on November 8 that diagnostic testing is necessary when identification could influence treatment or public health decisions. No unique symptom profile exists for PJ.2.1, and evidence is insufficient to show it causes more severe illness than earlier variants. High-risk groups, including older adults and those with chronic conditions, should seek urgent care for breathing difficulty or chest pain.
