WHO reveals symptoms of new coronavirus variant

“Therefore, based on symptoms alone, it is impossible to determine with certainty which respiratory virus caused the infection,” the WHO said.

The organization stressed that testing may be required in cases where identifying the cause of the illness could affect treatment decisions or public health measures.

“At present, there is insufficient evidence to conclude that PJ.2.1 causes different symptoms or more severe disease compared with other circulating SARS-CoV-2 variants,” the organization said.

The WHO noted that the new strain is a variant of the virus that causes COVID-19 and should not be regarded as something separate from the coronavirus.

The organization also said that the risk of the new COVID-19 variant spreading worldwide is increasing and noted that it is closely monitoring its spread.

Elena Malinnikova, a doctor of medical sciences, infectious disease specialist and virologist, previously said that severe sore throat and a longer period of weakness after illness may distinguish PJ.2.1 from other variants.
