MOSCOW: Symptoms of the new Covid-19 strain PJ.2.1 may be similar to those of a cold or flu, and testing is necessary, the World Health Organisation (WHO) said, reported Sputnik/RIA Novosti.
"Symptoms of Covid-19, influenza and other respiratory infections can overlap. Therefore, based on symptoms alone, it is impossible to determine with certainty which respiratory virus caused the infection," the WHO said.
Testing may be required in cases where establishing the cause of the illness could affect treatment decisions or public health decision-making, the organisation noted.
The WHO's Russian office earlier said that the risk of the new coronavirus strain PJ.2.1 spreading globally was increasing.
