WHO Announces New COVID-19 Variant PJ.2.1 Spreading in US, Europe, Australia
The World Health Organization has announced a new COVID-19 variant, PJ.2.1, is spreading rapidly in the US, Europe, and Australia, prompting global monitoring and research. The variant, first detected in Ontario, Canada on May 2, 2024, evolved from the JN.1 family branch MC.10.1.7 with significant spike protein mutations. However, WHO has not classified it as a Variant of Concern, and no evidence suggests it causes more severe illness or escapes current vaccine immunity. Common symptoms include fever, sore throat, cough, runny nose, headache, body aches, and fatigue. Health officials advise against panic, recommending masks and hand hygiene for elderly and high-risk individuals in crowded places.
