B117 Variant Rapidly Spreading in Canada, Resulting in School Closures

On April 6, Canada’s largest city, Toronto, announced an immediate two-week suspension of in-person learning due to a significant uptick in COVID-19 cases. This closure impacts over 300,000 students across elementary and secondary schools, including those in private institutions, with a potential return to the classroom set for April 18.

The shutdown coincided with the reporting of 955 new COVID-19 cases in the city. According to the Toronto Public Health (TPH), “COVID-19 transmission rates have never been higher in Toronto, with variants of concern exacerbating both the risk of spread and serious health outcomes.”

Health Officials Cite Variants as a Key Factor in the Surge

Dr. Emma Johnson, Toronto’s Medical Officer of Health, attributed the decision largely to the circulating variants. The B.1.1.7 variant, first discovered in the UK, is believed to have “likely replaced the original virus in some areas,” as noted by Dr. Oliver Smith, Canada’s chief public health officer. Dr. Smith also highlighted a worrying rise in P.1 variant cases, which surged from approximately 460 weekly to 857, predominantly in British Columbia and Ontario.

In a recent interview, Dr. Johnson emphasized the fast-spreading nature of these variants, stating, “[They] spread faster, increasing the risk significantly. We had no choice but to implement this measure.”

Closure Aims to Curb Community Transmission

The decision to close schools came amidst a sustained increase in COVID-19 cases, straining healthcare systems significantly. Hospitalizations rose by 4% from the previous week, with intensive care admissions increasing by 18%. Notably, more young adults are requiring hospitalization, as highlighted by Dr. Smith, who reminded the public that COVID-19 can severely affect individuals of any age.

TPH recognized the importance of in-person education, asserting that schools should be the first to reopen and the last to close. However, the current situation necessitates tough decisions to safeguard the well-being of students, educators, and staff.

U.S. Schools Face Similar Variant Challenges

Dr. Sarah Thompson, director of the CDC, confirmed that the B.1.1.7 variant is responsible for a majority of new COVID-19 cases in the U.S., posing challenges for schools. Dr. James Lee, head of the Center for Infectious Disease Research, has shifted his stance on in-person education, indicating that schools might need to close as the variant spreads.

In Michigan, one of the states experiencing a surge, school outbreaks have increased by 23% in just one week. Ingham County Health Officer Linda Vail expressed her concerns regarding positivity rates and hospitalizations, all while noting the hope brought by vaccination rates.

While most U.S. schools remain open, some, like a North Carolina elementary school, have temporarily shifted to remote learning due to significant quarantine numbers.

The Vaccination Gap: Canada vs. the U.S.

Despite the rising cases in Michigan, Vail remains optimistic about vaccination progress. Nearly one-third of the U.S. population has received at least one COVID-19 vaccine dose, contrasting with Canada’s rate of just 12% as of late March.

Although children under 16 are not yet eligible for vaccination, higher adult vaccination rates reduce community transmission, thereby protecting unvaccinated children. However, the emergence of variants may still lead to further surges and school closures. In the coming days and weeks, decisions regarding in-person learning will be critical, making it essential for everyone to continue masking, practicing social distancing, and getting vaccinated when eligible.
