The new coronavirus variant PJ.2.1, first detected in Canada in May 2026, has started to spread globally. According to the World Health Organization (WHO), this strain has symptoms that can easily be confused with the common flu or a cold.
Symptoms and Their Manifestations
The main symptoms of PJ.2.1 include:
- increased temperature;
- cough;
- sore throat;
- runny nose;
- headache;
- body aches;
- severe fatigue.
These manifestations may initially appear as mild cold symptoms, making diagnosis challenging. A specific test may be required to accurately identify the pathogen.
At-Risk Groups and Recommendations
According to WHO, the groups most vulnerable to severe illness remain:
- elderly individuals;
- pregnant women;
- people with chronic illnesses;
- individuals with weakened immune systems.
These groups should pay special attention to their health and seek medical advice at the first sign of symptoms.
Scientific Research and Observations
Researchers have identified genetic changes in the PJ.2.1 variant that may facilitate its faster spread. However, WHO currently has no evidence that this variant causes a more severe course of the disease or new symptoms compared to other coronavirus strains.
