October 25, 2020 – Update on COVID-19 from Dr. Theresa Tam – Net Newsledger

Published

 on


OTTAWA – In lieu of an in-person update to the media, Dr. Theresa Tam, Canada’s Chief Public Health Officer, issued the following statement today:

“As the resurgence of COVID-19 activity continues in Canada, we are tracking a range of epidemiological indicators to monitor where the disease is most active, where it is spreading and how it is impacting the health of Canadians and public health, laboratory and healthcare capacity. The following is the latest summary on national numbers and trends, and the actions we all need to be taking to maintain COVID-19 at manageable levels across the country.

Since the first cases were reported in March 2020, there have been 211,732 cases of COVID-19, including 9,888 deaths reported in Canada; these cumulative numbers tell us about the overall burden of COVID-19 illness to date. Though the cumulative number is high and continues to increase, it is important to remember that the vast majority of Canadians remain susceptible to COVID-19. This is why it is important for everyone to continue with individual precautions that will keep ourselves, our families and our communities safer.

At this time, there are 23,965 active cases across the country. The latest national-level data indicate daily averages of 2,488 new cases (Oct 16-22) and 74,719 people tested, with 3.1% testing positive (Oct 11-17). Outbreaks continue to contribute to COVID-19 spread in Canada. These vary in size from just a few cases to larger clusters occurring in a range of settings including long term care and assisted living facilities, schools, congregate living settings, industrial work settings and large social gatherings. Larger clusters tell us those closed and crowded settings and/or not sufficiently maintaining public health practises, such as physical distancing and mask-wearing, can amplify spread of the virus.

The number of people experiencing severe illness continues to increase. Provincial and territorial data indicate that an average of 1,010 people with COVID-19 were being treated in Canadian hospitals each day during the most recent 7-day period (Oct 16-22), including 209 of whom were being treated in intensive care units. During the same period, there was an average of 23 COVID-19-related deaths reported daily.

As hospitalisations and deaths tend to lag behind increased disease activity by one to several weeks, the concern is that we have yet to see the extent of severe impacts associated with the ongoing increase in COVID-19 disease activity. As well, influenza and respiratory infections typically increase during the Fall and Winter, placing increased demands on hospitals. This is why it is so important for people of all ages to maintain public health practises that keep respiratory infection rates low.

Canada needs a collective effort to sustain the public health response through to the end of the pandemic, while balancing the health, social and economic consequences. We can all do our part by keeping our number of in-person close contacts low and committing to proven effective public health practises; stay home/self-isolate if you have any symptoms, maintain physical distancing, wear a face mask as appropriate, and keep up with hand, cough and surface hygiene. Canadians can also go the extra mile by sharing credible information on COVID-19 risks and prevention practises and measures to reduce COVID-19 in communities and by downloading the COVID Alert app to help limit the spread of COVID-19.

Interior Health delivers nearly 800K immunization doses in 2023

Published

 on

Interior Health says it delivered nearly 800,000 immunization doses last year — a number almost equal to the region’s population.

The released figure of 784,980 comes during National Immunization Awareness Week, which runs April 22-30.

The health care organization, which serves a large area of around 820,000,  says it’s using the occasion to boost vaccine rates even though there may be post-pandemic vaccine fatigue.

“This is a very important initiative because it ensures that communicable diseases stay away from a region,” said Dr. Silvina Mema of Interior Health.

However, not all those doses were for COVID; the tally includes childhood immunizations plus immunizations for adults.

But IHA said immunizations are down from the height of the pandemic, when COVID vaccines were rolled out, though it seems to be on par with previous pre-pandemic years.

Interior Health says it’d like to see the overall immunization rate rise.

“Certainly there are some folks who have decided a vaccine is not for them. And they have their reasons,” said Jonathan Spence, manager of communicable disease prevention and control at Interior Health.

“I think there’s a lot of people who are hesitant, but that’s just simply because they have questions.

“And that’s actually part of what we’re celebrating this week is those public health nurses, those pharmacists, who can answer questions and answer questions with really good information around immunization.”

Mima echoed that sentiment.

“We take immunization very seriously. It’s a science-based program that has saved countless lives across the world and eliminated diseases that were before a threat and now we don’t see them anymore,” she said.

“So immunization is very important.”

Remnants of bird flu virus found in pasteurized milk, FDA says

Published

 on

The U.S. Food and Drug Administration said Tuesday that samples of pasteurized milk had tested positive for remnants of the bird flu virus that has infected dairy cows.

The agency stressed that the material is inactivated and that the findings “do not represent actual virus that may be a risk to consumers.” Officials added that they’re continuing to study the issue.

“To date, we have seen nothing that would change our assessment that the commercial milk supply is safe,” the FDA said in a statement.

The announcement comes nearly a month after an avian influenza virus that has sickened millions of wild and commercial birds in recent years was detected in dairy cows in at least eight states. The Agriculture Department says 33 herds have been affected to date.

FDA officials didn’t indicate how many samples they tested or where they were obtained. The agency has been evaluating milk during processing and from grocery stores, officials said. Results of additional tests are expected in “the next few days to weeks.”

The PCR lab test the FDA used would have detected viral genetic material even after live virus was killed by pasteurization, or heat treatment, said Lee-Ann Jaykus, an emeritus food microbiologist and virologist at North Carolina State University

“There is no evidence to date that this is infectious virus and the FDA is following up on that,” Jaykus said.

Officials with the FDA and the USDA had previously said milk from affected cattle did not enter the commercial supply. Milk from sick animals is supposed to be diverted and destroyed. Federal regulations require milk that enters interstate commerce to be pasteurized.

Because the detection of the bird flu virus known as Type A H5N1 in dairy cattle is new and the situation is evolving, no studies on the effects of pasteurization on the virus have been completed, FDA officials said. But past research shows that pasteurization is “very likely” to inactivate heat-sensitive viruses like H5N1, the agency added.

Matt Herrick, a spokesman for the International Dairy Foods Association, said that time and temperature regulations for pasteurization ensure that the commercial U.S. milk supply is safe. Remnants of the virus “have zero impact on human health,” he wrote in an email.

Scientists confirmed the H5N1 virus in dairy cows in March after weeks of reports that cows in Texas were suffering from a mysterious malady. The cows were lethargic and saw a dramatic reduction in milk production. Although the H5N1 virus is lethal to commercial poultry, most infected cattle seem to recover within two weeks, experts said.

To date, two people in U.S. have been infected with bird flu. A Texas dairy worker who was in close contact with an infected cow recently developed a mild eye infection and has recovered. In 2022, a prison inmate in a work program caught it while killing infected birds at a Colorado poultry farm. His only symptom was fatigue, and he recovered.

Canada Falling Short in Adult Vaccination Rates – VOCM

Published

 on


Canada is about where it should be when it comes to childhood vaccines, but for adult vaccinations it’s a different story.

Dr. Vivien Brown of Immunize Canada says the overall population should have rates of between 80 and 90 per cent for most vaccines, but that is not the case.

She says most children are in that range but not for adult vaccines and ultimately the most at-risk populations are not being reached.

She says the population is under immunized for conditions such as pneumonia, shingles, tetanus, and pertussis.

Brown wants people to talk with their family physician or pharmacist to see if they are up-to-date on vaccines, and to get caught up because many are “killer diseases.”
