REGINA -- As COVID-19 variants continue to spread in Saskatchewan, it remains unclear exactly how many confirmed and presumptive variant cases have been detected in Saskatchewan schools. The government confirmed 66 more variant cases Tuesday, bringing the total number of confirmed cases to 136. The Regina zone accounts for 122 – or 90 per cent – of the confirmed variant cases reported in the province. During the government’s COVID-19 update Tuesday, Saskatchewan’s chief medical health officer Dr. Saqib Shahab said Variants of Concern (VoC) are 70 per cent more transmissible than the original strain of COVID-19. He said with the original strain, three out of 10 restaurant staffers would become symptomatic after a COVID-19 exposure. But with the B.1.1.7 variant, first found in the U.K., it would be 10 out of 10.
