On November 8, 2026, the World Health Organization (WHO) reported a new strain of coronavirus, PJ.2.1, which was first identified in Canada in May 2026. It is currently spreading actively in North America and Europe.
Symptoms of the New Strain
The symptoms of PJ.2.1 are similar to those of a common cold or flu. The main manifestations include:
- increased temperature;
- cough;
- runny nose;
- sore throat;
- headache;
- body aches;
- severe fatigue.
These symptoms can complicate diagnosis, as they are difficult to distinguish from other respiratory infections such as the flu.
At-Risk Groups
WHO notes that the highest risk for severe disease progression is among:
- elderly people;
- pregnant women;
- individuals with chronic diseases;
- people with weakened immune systems.
These groups should be particularly cautious and take additional measures to prevent infection.
Potential Threats and Research
Researchers have identified genetic changes in the PJ.2.1 strain that may facilitate its faster spread. However, at this time, WHO has no evidence that this variant causes a more severe disease course or new symptoms compared to other coronavirus strains. The study of PJ.2.1's properties is ongoing, and scientists continue to monitor its spread.
