The World Health Organization (WHO) is closely monitoring two new COVID-19 subvariants of Omicron, the highly transmissible variant of concern now dominant around the world.
Since January, more than 300 cases of the BA.4 and BA.5 sub-lineages have been reported in several countries, according to data by cov-lineages.org. Most of those cases have been detected in South Africa.
As of May 3, Canada had detected three cases – two of BA.4 and one of BA.5, the Public Health Agency of Canada (PHAC) told Global News on Friday.
Wow! 3 cases! But a new wave?
