Number of active cases also highest ever at 1,412, with 42 patients in hospital.
British Columbia has hit a new record for the number of new COVID-19 cases confirmed in one day in the province, posting 139 on Thursday.
Provincial Health Officer Dr. Bonnie Henry said these new cases bring the number of active cases of infection to a new high of 1,412 out of 6,830 confirmed since the pandemic began.
The number of patients in hospital with COVID-19 has risen to 42, an increase of 10 since Tuesday and the highest number in B.C. since May 21. There are currently 14 people in intensive care.
Thursday marked the gradual return to school for many B.C. children, and Henry tried to reassure families who might be feeling anxious, saying that schools have made it through measles and meningitis outbreaks, and they will make it through COVID-19 as well.
"I think it is important to recognize all the work done by educators, principals, parents to get schools ready this year," she said. "We will all be learning over the next few weeks."
However, acknowledging there will be transmission in schools, Henry said local health officials will make sure that everyone affected is notified.
