The number of active cases of COVID-19 in First Nations and Inuit communities continues on an overall downward trend.
According to the latest data from Indigenous Services Canada, there were 906 active cases of COVID-19 reported in First Nations as of Dec. 7. This is down from the 1,132 active cases that were reported on Nov.15.
In the week ending Dec. 4, First Nations in British Columbia recorded the highest number of newly reported cases among the provinces with 65, with First Nations in Ontario recording 26 and First Nations in Quebec recording 22 cases.
According to the Nunavik Regional Board of Health and Social Services, there were no new cases as of Dec. 7 bringing the total active cases to 42 in Inuit communities in northern Quebec.
Since the pandemic began, there have been 50,966 cases in First Nations communities. To date there have been 544 deaths, 2,369 total hospitalizations, and 49,516 recovered cases.
Total cases in First Nations communities per region reported as of Dec. 7:
British Columbia: 6,172
Sandy Bay dealing with outbreak
In Sandy Bay First Nation, about 130 kilometres north of Winnipeg, the chief and council have been dealing with an ongoing outbreak.
“We have had at least one new case every day since the end of September,” said Randal Roulette, a Sandy Bay band councillor.
Roulette said most of the cases have been linked to the delta variant and the local school has been shut down since September.
Between the end of September and Dec. 6, the community has had 178 total cases and three deaths.
Roulette said the community has implemented strict stay-at-home measures for people who are confirmed to have COVID-19 as well as anyone who has been identified as a close contact.
He said it has been difficult for some of the larger households where people are testing positive days apart, causing prolonged isolation periods for the tenants.
“If we have a house of nine people, then they don’t all become positive at the same time, so then the isolation kind of starts … like a chain reaction where they can be isolating for over a month sometimes.”
Vaccination numbers in First Nations and Inuit communities
A total of 891,972 vaccine doses have been administered to individuals aged 12 years and older in 687 First Nations and Inuit communities as of Dec. 1. Of that number, 383,602 were second doses.
Several regions have also begun offering third doses of the vaccine on First Nations or to elders over a specific age, however no data on third doses is available through Indigenous Services Canada to date.

Over 1.2 million people died from drug-resistant infections in 2019 – study
More than 1.2 million people died in 2019 from infections caused by bacteria resistant to multiple antibiotics, higher than HIV/AIDS or malaria, according to a new report published on Thursday.
Global health officials have repeatedly warned about the rise of drug-resistant bacteria and other microbes due to the misuse and overuse of antibiotics, which encourages microorganisms to evolve into “superbugs”.
The new Global Research on Antimicrobial Resistance report, published in The Lancet, revealed that antimicrobial resistance (AMR) was directly responsible for an estimated 1.27 million deaths and associated with about 4.95 million deaths. The study analysed data from 204 countries and territories.
“These new data reveal the true scale of antimicrobial resistance worldwide… Previous estimates had predicted 10 million annual deaths from AMR by 2050, but we now know for certain that we are already far closer to that figure than we thought,” said Chris Murray, co-author of the study and a professor at the University of Washington.
Last year, the World Health Organization warned that none of the 43 antibiotics in development or recently approved medicines were enough to combat antimicrobial resistance.
Cornelius Clancy, professor of Medicine at the University of Pittsburgh, said one of the ways to tackle AMR is to look at a new treatment model.
“The traditional antibiotic model that we’ve had for past number of decades since penicillin. I think it is tapped out.”
Most of 2019’s deaths were caused by drug resistance in lower respiratory infections such as pneumonia, followed by bloodstream infections and intra-abdominal infections.
AMR’s impact is now most severe in Sub-Saharan Africa and South Asia, while around one in five deaths is in children aged under five years.
There was limited availability of data for some regions, particularly many low and middle-income countries, which may restrict the accuracy of the study’s estimates.
Clancy said the focus has been on COVID-19 for the past two years, but AMR is a “long-term kind of challenge”.

Study casts doubt on reliability of rapid antigen tests in kids; COVID transmission through breastmilk unlikely
The following is a summary of some recent studies on COVID-19. They include research that warrants further study to corroborate the findings and that has yet to be certified by peer review.
Rapid antigen tests may be unreliable in children
When used in children, rapid antigen tests for detecting the coronavirus do not meet accuracy criteria set by the World Health Organization and U.S. and UK device regulators, according to researchers who reviewed 17 studies of the tests.
The trials evaluated six brands of tests in more than 6,300 children and teenagers through May 2021. In all but one study, the tests were administered by trained workers. Overall, compared to PCR tests, the antigen tests failed to detect the virus in 36% of infected children, the researchers reported on Tuesday in BMJ Evidence-Based Medicine. Among children with symptoms, it missed 28% of infections. Among infected kids without symptoms, the tests missed the virus in 44%. Only about 1% of the time did the tests mistakenly diagnose the virus in a child who was not actually infected.
Given that more than 500 antigen tests are available in Europe alone, the authors said, “the performance of most antigen tests under real-life conditions remains unknown.” But the new findings “cast doubt on the effectiveness” of rapid antigen tests for widespread testing in schools, they concluded.
Breastmilk transmission of COVID-19 unlikely
A new study appears to confirm smaller, earlier studies that suggested nursing mothers are unlikely to transmit the coronavirus in breastmilk.
Between March and September 2020, researchers obtained multiple breastmilk samples from 110 lactating women, including 65 with positive COVID-19 tests, 36 with symptoms who had not been tested, and a control group of 9 women with negative COVID-19 tests. Seven women (6%) – six with positive tests and one who had not been tested – had non-infectious genetic material (RNA) from the virus in their breastmilk, but none of the samples had any evidence of active virus, according to a report published on Wednesday in Pediatric Research. Why breastmilk would contain coronavirus RNA but not infectious virus is unclear, said study leader Dr. Paul Krogstad of the David Geffen School of Medicine at UCLA, “Breastmilk is known to contain protective factors against infection, including antibodies that reflect both the mother’s exposure to viruses and other infectious agents and to vaccines she has received,” he noted.
The U.S. Centers for Disease Control and Prevention (CDC) advises that before breastfeeding, bottle-feeding, or expressing milk, women with COVID-19 should wash their hands or use hand sanitizer with at least 60% alcohol. The CDC also recommends that they wear a mask when within 6 feet (1.8 meters) of the baby.
New technique may speed vaccine, antibody drug development
Researchers are working on a way to speed development of vaccines and monoclonal antibody drugs for COVID-19 and other illnesses, shortening the time from collection of volunteers’ blood samples to identification of potentially useful antibodies from months to weeks.
As described in Science Advances on Wednesday, the new technique employs cryo-electron microscopy, or cryoEM, which involves freezing the biological sample to view it with the least possible distortion. Currently, “generation of monoclonal antibodies involves several steps, is expensive, and typically takes somewhere on the order of two to three months, and at the end of that process you still need to perform structural analysis of the antibodies” to figure out where they attach themselves to their target, and how they actually work, explained Andrew Ward of Scripps Research Institute in La Jolla, California.
In experiments using the new approach to look for antibodies to HIV, “we flipped the process on its head… by starting with structure,” Ward said. Because cryoEM affords such high resolution, instead of having to laboriously sort through antibody-producing immune cells one by one to identify promising antibodies, the process of identifying antibodies, mapping their structure and seeing how they are likely to attack viruses and other targets goes much faster, he added. “The ongoing COVID-19 pandemic has highlighted the need for such robust and rapid technologies,” his team concluded.

Vaccination plus infection offered most protection during Delta surge, U.S. study shows – CBC News
Protection against the previously-dominant Delta variant was highest among people who were both vaccinated and had survived a previous COVID-19 infection, according to a report published Wednesday by the U.S. Centers for Disease Control and Prevention (CDC).
The report also found those who had previously been infected with COVID-19 were better protected against the Delta variant than those who were vaccinated alone, suggesting that natural immunity was a more potent shield than vaccines against that variant, California and New York health officials reported on Wednesday.
Protection against Delta was lowest among those who had never been infected or vaccinated, the CDC report continued.
“The evidence in this report does not change our vaccination recommendations,” Dr. Ben Silk of the CDC and one of the study’s authors told a media briefing.
“We know that vaccination is still the safest way to protect yourself against COVID-19,” he said.
The findings do not apply to the Omicron variant of the virus, which now accounts for 99.5 per cent of COVID-19 cases in the United States.
Study includes data from May to November
For the study, health officials in California and New York gathered data from May through November, which included the period when the Delta variant was dominant.
It showed that people who survived a previous infection had lower rates of COVID-19 than people who were vaccinated alone.
That represented a change from the period when the Alpha variant was dominant, Silk told the briefing.
“Before the Delta variant, COVID-19 vaccination resulted in better protection against a subsequent infection than surviving a previous infection,” he said.
In the summer and fall of 2021, however, when Delta became the predominant circulating iteration of the virus in the United States, “surviving a previous infection now provided greater protection against the subsequent infection than vaccination,” he said.
But acquiring immunity through natural infection carries significant risks. According to the study, by Nov. 30, 2021, roughly 130,781 residents of California and New York had died from COVID-19.
The analysis did not include information on the severity of initial infection, nor does it account for the full range of illness caused by prior infection.
One important limitation to the study was that it ended before administration of vaccine booster doses was widespread.
WATCH | Experts agree the science behind booster shots is sound:
‘Clearly shows’ vaccines provide safest protection
Dr. Erica Pan, state epidemiologist for the California Department of Public Health, said in an email that the study “clearly shows” that vaccines provide the safest protection against COVID-19 and they offer added protection for those with prior infections.
“Outside of this study, recent data on the highly contagious Omicron variant shows that getting a booster provides significant additional protection against infection, hospitalization and death,” Pan said.
Silk said the CDC is studying the impact of vaccination, boosters and prior infection during the Omicron surge and expects to issue further reports when that data becomes available.
So far, Omicron has proven to evade some level of immunity from both vaccination and previous infection, but vaccines are still largely preventing serious illness and death.
An Israeli hospital on Monday also said preliminary research indicates a fourth dose of leading mRNA-based vaccines provides only limited defence against infection from the variant.
