The predominant sub-variants of Omicron in Quebec

The three new sub-variants of Omicron that are causing an increase in infections in Europe and the United States now account for just over half of the cases in Quebec. Despite the increase in the number of cases and hospitalizations, the situation is not a cause for concern, but it still calls for a certain vigil.

The picture of the variables has changed significantly in recent weeks. The BA.2.12.1 variant, which has caused an increase in cases recently in the United States, now accounts for more than a third of new cases in the province, according to data from the National Institute of Public Health in Quebec (INSPQ). Responsible for the increases in many European countries, the BA.4 and BA.5 subvariants account for 16% of infections. In the UK, daily infections are once again near their highest levels since the start of the pandemic. Italy recorded 30,526 new cases in 24 hours, from Saturday to Sunday, an increase of 63.4% in seven days, according to the latest report from the Ministry of Health. France will not be defeated, as the spread of the virus has accelerated for ten days in mainland France, and the infection rate is more than 44,000 cases per day.

The pressure must increase

Quebec recorded an increase of 43 hospitalizations on Wednesday. Currently, 1,084 people are hospitalized in connection with the COVID-19 virus. This represents an 8% increase in one week. Moreover, the National Institute for Excellence in Health and Social Services (INESSS) estimates that the increase in cases observed in recent weeks should lead to an increase in the number of hospitalizations. The number of people admitted should increase to about 100 people per day within two weeks. INESSS notes that this increase is due to people who have been hospitalized due to COVID-19 and not just to patients who have been admitted for another reason, but who have tested positive for the coronavirus. After recently approaching 1,000 hospitalized patients, Quebec should have 1,378 within two weeks.

What does the sewage say?

Since no PCR screening tests are available in the general population, INSPQ has been publishing wastewater analysis results since Wednesday in order to follow the overall trend of COVID-19. Since the beginning of June, the organization’s reports show marked increases in the presence of SARS-CoV-2 in several cities, including Montreal, Quebec, Gatineau or Laval. In Quebec, wastewater collection began in the spring of 2022. The program is supposed to eventually be rolled out in about fifteen municipalities. considered ds Matthew Oughton, an infectious disease specialist at Jewish General Hospital, says there is a need to “widen access to testing” because rapid tests are “more likely to miss infections.” “In the current context, I think we need to take concrete measures. For the rest, it will be necessary to be careful, especially for the elderly or with risk factors. It means wearing a mask and staying alert to our risk.”

Cases on the rise

Screening results by PCR tests, although partial and primarily relevant to health care workers, continue their upward trend. Quebec reported 1,110 new cases on Wednesday, bringing the daily average to 795. So the trend is up 19% in one week. In addition to the cases detected by PCR tests, 712 people in recent days have reported a positive result from a rapid test they administered themselves. Self-reported cases, which were not included in daily reported cases, increased by 29% over a one-week period.

Consequences of getting injured again

A recent preliminary study published on Research Square It also indicates that people with COVID-19 are at greater risk. The study notes that reinfection with COVID-19 “contributes to additional risks of all-cause mortality, hospitalization and adverse effects on the health of pulmonary systems.” US researchers Ziyad Al-Ali, Benjamin Boye, and Yan Ze also note that this risk appears to be “clear” in unvaccinated people or in people who received two or fewer doses. Their study caused a lot of reactions in the scientific world. Quickly, some observers used it to make clear that re-infection is not “benign,” as some claim. “You can no longer rely on previous infections to protect yourself. There is increasing evidence that Omicron’s immune response to natural infections does not really provide significant protection against other variants.”s Matthew Otton on this.
