WHO Warns of New COVID Variant PJ.2.1 with Flu-Like Symptoms

The World Health Organization (WHO) has reported that symptoms of the new COVID-19 variant PJ.2.1 can resemble the flu, emphasizing the need for testing to confirm the cause of infection. The WHO stated that symptoms of COVID-19, influenza, and other respiratory infections overlap, making it impossible to identify the specific virus based on symptoms alone. Testing may be necessary when identifying the cause could affect treatment strategies or public health decisions. The WHO's regional office in Russia previously reported an increased global transmission risk for PJ.2.1, which remains under monitoring. Russian virologist Dr Elena Malinnikova noted that severe sore throat and longer post-viral fatigue may distinguish this variant.
