Health officials announced 564 new cases and four more deaths on Thursday.
There are now 248 people in hospital with COVID-19, including 63 in intensive care.
To date, 1,376 people in B.C. have lost their lives to COVID-19.
There are currently 4,743 active cases of coronavirus in the province.
246 cases of variants of concern have been identified.
So far, 298,851 doses of a COVID-19 vaccine have been administered in B.C., with 86,746 of those being second doses.
The seven-day rolling average of new COVID-19 cases and the number of patients in hospital with the disease continue to climb in B.C., and officials are expressing concern about the potential for a third wave of the pandemic.
In Thursday's COVID-19 briefing, Provincial Health Officer Dr. Bonnie Henry announced 564 new cases and four more deaths. A total of 248 people are in hospital with the disease, including 63 in intensive care, out of 4,743 active cases.
The latest numbers mean active cases and the rolling average of new cases are at their highest points since Jan. 13 and the number of hospitalizations is the highest since Feb. 5.
"We are in a new place right now in the COVID-19 pandemic," Henry said.
"We can't let the successes of these great vaccines that we have now be diminished by a surge in cases."
Since the province's vaccination program began in late 2020, 298,851 doses of a COVID-19 vaccine have been administered, including 86,746 second doses.
B.C. now expects every eligible adult who wants a vaccine will receive their first dose by July. The plan is to space out doses by four months, a much longer gap than what's recommended by the manufacturers.
But as the vaccination program ramps up, there is growing concern about transmission of faster spreading variants within the community.
B.C. has now confirmed a total of 246 cases of variants of concern, and public health has not been able to identify the source of transmission for about a quarter of those.
