The highly transmissible Delta variant is the dominant variant and is causing an increase in cases in most public health regions of Ontario, the advisers wrote in Tuesday’s report.

“The tests have not increased, but the positivity is increasing. This is a real increase in cases, ”they wrote.

“The efficacy of vaccines in Ontario remains very high, but experience in other countries suggests that we will need to boost immunity with third doses. “

The report also discusses the Omicron variant, which is now present in Ontario and, advisers wrote, likely to push cases beyond current projections. But even without Omicron, advisers explained, the intensive care occupancy rate will likely rise to 250 to 400 beds in January, “putting hospitals under pressure again.

“To control the cases and the impact on our health system, we need to increase immunization (especially 5-11 year olds) and continue to use public health measures to reduce transmission now,” the report said.

“In South African data, vaccination appears to protect against serious illnesses caused by Omicron and most hospitalizations are in unvaccinated people. There is likely an increased risk of re-infection, even among people who have had COVID-19, which underscores the importance of vaccination.

“The low global immunization coverage means that we can expect new variants to emerge. “

This story will be updated this afternoon following a presentation by Ontario’s Chief Medical Officer, Dr. Kieran Moore.
