Canadian experts warn of 3rd wave
OTTAWA: Health experts in Canada have warned of a third wave of the Covid-19 pandemic after variants of the virus were reported across nine provinces.
As of February 13, Canada reported 429 cases of the UK B.1.1.7 variant, 28 cases of the South African B.1.351 variant, and one of the P.1 Brazilian strain, reports Xinhua news agency.
"Although it is normal for variants to emerge as viruses continuously evolve, some variants are considered ' variants of concern' because they spread more easily, some may cause more severe illness, or current vaccines may be less effective against them," Theresa Tam, Canada's chief public health officer, said in a statement on Saturday.
"This is why we need to maintain the strictest vigilance in our public health measures and individual practices. This will help to prevent these variants from re-accelerating the epidemic and making it much more difficult to control," Tam added.
