New coronavirus variant PJ.2.1 draws concern with flu-like symptoms
CNN Central News & Networks / ITDC India ePress / ITDC News / Agencies, Bhopal:
A new coronavirus variant, PJ.2.1, is under the watch of health experts after being reported in several countries. It was first identified in Ontario, Canada, in May 2026. Cases have since also been reported in the United States, Europe, Asia and parts of Australia. Because its symptoms resemble those of the common cold and flu, identifying the infection may be challenging. However, so far, no firm evidence has been found that this variant causes more severe disease than earlier forms of coronavirus.
What are its symptoms?
According to the World Health Organization, the symptoms of coronavirus and influenza can be very similar. These include fever, sore throat, persistent cough, runny or blocked nose, headache, body ache and fatigue. Some patients may also experience breathing difficulty and changes in the sense of taste or smell. It is difficult to distinguish between coronavirus and ordinary flu on the basis of symptoms alone. Testing is necessary when required.
Changes in spike protein keep scientists alert
Several genetic changes have been found in the spike protein of PJ.2.1. Early laboratory studies have shown an increased ability to enter some cells. However, there is no evidence of a major increase in its ability to evade antibodies generated by vaccination.
What is the situation in India?
Reports available up to November 11, 2026, have not officially confirmed the presence of PJ.2.1 in India. Genome sequencing and monitoring of new coronavirus forms in the country are carried out through INSACOG.
Elderly people, those with weakened immunity and patients already battling serious illnesses should take special precautions. Medical advice should be sought if symptoms appear. Wearing masks in crowded places, hand hygiene and maintaining adequate ventilation in homes can also help reduce the risk of infection.
