British Columbia reached a grim milestone this week, recording 24 new deaths due to COVID-19, pushing the total number of people who have died since the beginning of the pandemic over 4,000 to 4,037.

The province is reporting a slight drop in the number of people in hospital who have tested positive for COVID-19, while the number of patients in critical care with the virus remains the same.

On Thursday, the B.C. Centre for Disease Control shared its latest COVID-19 data, which showed 366 people in hospital — a decrease of about seven per cent —and 22 people in critical care, the same number as last week.

Deaths are now calculated based on whether they occurred within 30 days of a positive COVID-19 test, whether or not the virus has been confirmed as an underlying cause of death.

The government's weekly numbers, which it says are preliminary, are often changed retroactively due to delays in the count and the new way the province measures weekly cases, hospitalizations and deaths.

The numbers released Thursday are part of an approach from B.C. health officials that began in April, both in the move to weekly reporting and in how certain metrics are calculated.

There were 877 new cases reported as of Aug. 13, a decrease of about two per cent, bringing the total number of confirmed cases in B.C. to date to 381,049.

The province says it likely underestimates actual case numbers as most people are testing themselves, and there are fewer lab-reported tests.

Across the province, test positivity rates saw another slight decrease to 9.1 per cent for the week ending Aug. 13, down one per cent from the week before.

Provincial Health Officer Dr. Bonnie Henry has said anything above a five per cent test-positivity rate is a general indicator of ongoing community transmission.

The B.C. Centre for Disease Control says while there continues to be week-to-week variability, SARS-CoV-2 viral loads in Metro Vancouver wastewater generally continue to decrease from recent peaks at the end of June and early July.

UBC researchers identify 'weak spot' in COVID-19 variants

Researchers at the University of British Columbia (UBC) have discovered what they describe as a "weak spot" in all of the major variants of the virus that causes COVID-19 — potentially opening the door for new treatments.

In a peer-reviewed study published Thursday, the research team said it found a largely consistent soft spot — like a dent in the virus's spike protein armour — that has survived the coronavirus's mutations to date.

They determined that a fragment of a certain antibody could "effectively neutralize" all the variants to some degree by exploiting this vulnerability.

The scientists said they hope to use the new information to design antibodies capable of taking advantage of the weak spot in all different variants and mutations of the COVID-19 virus — a so-called "master key" that could help prevent serious infection.
