PJ.2.1 COVID Variant: What Indians Need to Know

A new SARS-CoV-2 variant, PJ.2.1, first detected in Canada in May 2026, has spread to multiple countries including the US, Singapore, and France, prompting global health monitoring. The variant, a saltation strain with significant spike protein mutations, can bind easily to human cells and partially evade prior immunity. Symptoms resemble common cold or flu, including fever, sore throat, and cough, making COVID testing essential for accurate diagnosis. Experts say there is no evidence PJ.2.1 causes more severe illness, advising precautions like mask-wearing in crowded places and testing if symptoms persist. High-risk individuals should consult doctors about booster doses.
