Prevalence of Delta variant doubles in B.C. as authorities warn unvaccinated people of vulnerability – .


VANCOUVER – The BC Center for Disease Control reports that the disturbing variant of Delta has doubled in prevalence, despite the overall decline in COVID-19 cases. The news comes just as first-dose vaccinations are starting to level off, and federal health officials are warning the unvaccinated are increasingly at risk.

Late Friday afternoon, the BCCDC released its “Variants of Concern (VOCs) Weekly Update”. In this graph, a graph shows that after a brief drop, the Delta variant went from 6% of cases in B.C. on June 12 to 12% on June 19.

“British Columbia has moved to whole genome sequencing on all positive samples,” notes the report, which now shows 970 cases of the Delta variant, laboratory-identified as B.1.617.2, first discovered in India and spreading rapidly in several countries.

The B.1.1.7 Alpha variant, first identified in the UK, accounts for 48 percent of cases in British Columbia, while the P.1 Gamma variant, first identified in Brazil, has fallen to 40 percent.

The disturbing statistics come the same day that Canada’s top doctor warned that a pattern seen in other countries – of unvaccinated people easily becoming infected with the Delta variant and leading to an increase in cases – could also occur in our country. country.

“Experiences from other countries underscore the need to remain cautious as immunization coverage increases,” said Dr. Theresa Tam, Canada’s chief public health officer, on Friday.

“In addition, the relaxation of measures must be controlled, gradual and responsive to potential changes in disease activity until infection rates reach low and manageable levels,” Tam said. “For example, the UK has slowly and cautiously relaxed its measures as infection rates decline and immunization coverage spread, but has seen a recent resurgence fueled by the emergence and spread of the variant. Delta in younger, largely unvaccinated people. ”

Israel just reinstated its indoor mask mandate 10 days after lifting it as cases suddenly spike; the Delta variant and unvaccinated children are the key factors identified by officials there.

Tam’s modeling presentation predicts that unless Canada exceeds 80 percent of the total vaccinated population, the country could experience a fourth wave in the fall and winter.

British Columbia now has 76.2% of eligible people aged 12 and over vaccinated, but early doses have leveled off. While almost all fully vaccinated people appear to have mild to no symptoms if they are infected with variants, unprotected people are highly susceptible to Delta, which is 1.5 times more contagious and twice as virulent as the Alpha variant. .

To date, 3,530,063 British Columbians have had at least one injection. According to Statistics Canada, there were approximately 4,442,000 people over the age of 12 in the province in 2020, which means nearly a million people could be vaccinated against COVID-19 and its variants are currently unprotected. .
