Albertans had highest rate of COVID-19 antibodies due to infection in major national blood survey – CBC.ca

Published

 on


Albertans had a higher rate of COVID-19 antibodies due to a past infection than people in any other province, according to a major national blood survey conducted in early 2021.

The Canadian COVID-19 Antibody and Health Survey involved mailing tens of thousands of testing kits to people across the country.

Respondents were asked to use the kits to poke their fingers, collect a sample of their own blood, and return the sample by mail for testing at the National Microbiology Lab in Winnipeg.

The samples were tested for the presence of coronavirus antibodies — blood proteins created by people’s immune systems in response to the virus that can help them fight off future infections.

Participants were also asked to indicate their vaccination status to help researchers differentiate between antibodies from natural infection versus vaccination.

The survey ran from November 2020 to April 2021 but the bulk of the collection was done in January and February.

As such, it doesn’t offer a current estimate of COVID-19 antibodies but rather a snapshot of a period of time, largely this past winter.

Based on the blood-test results, Statistics Canada estimates that four per cent of Albertans had antibodies due to a past COVID-19 infection. (This estimate comes with a confidence interval of 2.6 per cent to 5.7 per cent, meaning the true proportion will fall in that range 95 times out of 100.)

That compares with a national rate of 2.6 per cent (with a confidence interval of 1.6 per cent to 3.2 per cent.)

Statistics Canada undertook the blood survey in partnership with the Public Health Agency of Canada, Health Canada and Canada’s COVID-19 Immunity Task Force.

The survey is seen as the most comprehensive study, to date, of immunity due to natural infection in Canada.

“This study is really unique in the fact that it’s able to provide statistically reliable data on the prevalence of antibodies in a representative sample of Canadians across the country,” said Peter Jiao, the head of Statistics Canada’s COVID-19 data team.

“And so the survey results, they’re going to be used by public health authorities and researchers to better understand how the virus has spread through the population.”

The number of actual COVID-19 infections has always been believed to be higher than the number of confirmed cases, because testing has not always been widely available and, even when it was, some people may not have known they were infected or did not seek testing for other reasons.

But the new data suggests the number of undiagnosed infections is actually lower than many had previously thought.

“The rates were really really low,” said Dr. Catherine Hankins with the COVID-19 Immunity Task Force.

Alberta government estimated 14% in spring

Alberta Premier Jason Kenney offered higher estimates in the spring.

In April, Kenney said the provincial government believed 10 per cent of Albertans had immunity to COVID-19 due to a past infection.

The following month, he said it was even higher.

“We estimate that about 14 per cent of Albertans have a degree of immunity through antibodies acquired through prior natural infection,” Kenney said, in announcing the province’s “Open For Summer” plan in late May.

The blood-survey study period didn’t catch all of Alberta’s third wave of COVID-19 in the spring, but the new data still suggests the province’s estimates were likely on the higher end, said Craig Jenne, a microbiology and infectious disease professor at the University of Calgary.

“Fewer people in the community are protected than perhaps were included in the initial modelling about when it’s safe to lift restrictions,” he said.

“So it’s probably a very strong warning that we have to be careful moving forward — that the potential for larger outbreaks to exist is still there — and we have to do our best to try and limit that spread.”

Should I be worried about monkeypox? A doctor answers questions as the outbreak spreads – CBS News

Published

 on


The World Health Organization said June 25 that monkeypox wasn’t yet a public health emergency of international concern. More than 4,000 cases have been reported worldwide, with about 250 in the U.S. And with public health officials unable to follow all chains of transmission, they’re likely undercounting cases. Everyone should be aware of its symptoms, how it spreads, and the risks of it getting worse.

Q: Should I be worried about monkeypox?

The American public is currently at low risk for monkeypox. It is spreading among men who have sex with men, but it is only a matter of time before it spreads to others. As of June 27, the European Centre for Disease Prevention and Control had reported 10 cases among women. Monkeypox is generally a mild disease but can be serious or even deadly for people who are immunocompromised, pregnant women, a fetus or newborn, women who are breastfeeding, young children, and people with severe skin diseases such as eczema.

But monkeypox could become endemic in the U.S. and around the world if it continues to spread unchecked.

Q: How does monkeypox spread?

Monkeypox is a viral infection, a close cousin of smallpox. But it causes a much milder disease.

It is transmitted through close contact, including sex, kissing, and massage — any kind of contact of the penis, vagina, anus, mouth, throat, or even skin. In the current outbreak, monkeypox has primarily been transmitted sexually.

Condoms and dental dams will reduce but won’t prevent all transmission because they protect only against transmission to and from the skin and mucosal surfaces that are covered by those devices. It’s important to know that the virus can enter broken skin and penetrate mucous membranes, like in the eyes, nose, mouth, genitalia, and anus. Scientists don’t know whether monkeypox can be transmitted through semen or vaginal fluid.

Monkeypox can be transmitted through respiratory droplets or “sprays” within a few feet, but this is not thought to be a particularly efficient mode of transmission. Whether monkeypox could be transmitted through aerosols, as covid-19 is, is unknown, but it hasn’t been documented so far.

It is not known whether monkeypox can be transmitted when someone doesn’t have symptoms.

Q: What are the common symptoms of monkeypox?

Symptoms of monkeypox may develop up to 21 days after exposure and can include fevers and chills, swollen lymph nodes, rash, and headaches.

It is not known whether monkeypox always shows any or all of those symptoms.

Experts currently think monkeypox, like smallpox, will always cause at least some of these symptoms, but that belief is based on pre-1980 science, before there were more sophisticated diagnostic tests.

Q: What does the monkeypox rash look like?

The monkeypox rash usually starts with red spots and then evolves into fluid-filled and then pus-filled bumps that may look like blisters or pimples. The bumps then open into sores and scab over. People with monkeypox should be considered infectious until after the sores scab over and fall off. Monkeypox sores are painful. The rash was often seen on palms and soles in the past, but many people in this outbreak have experienced external and internal lesions of the mouth, genitalia, and anus. People may also experience rectal pain or the sensation of needing to have a bowel movement when their bowels are empty.

Q: How do I get tested for monkeypox?

If you have symptoms of monkeypox, including oral, genital, or anal lesions, go to your nearest sexual health clinic for testing. A medical professional should swab any suspicious lesion for testing. There’s also emerging evidence that throat swabs may be useful in screening for monkeypox, but health officials in the U.S. are so far not recommending them.

Q: Is there a vaccine for monkeypox?

Yes. Two vaccines are effective in preventing monkeypox: the Jynneos vaccine and the ACAM2000 vaccine. The FDA has approved the Jynneos vaccine for preventing monkeypox and smallpox among people 18 and older. The ACAM2000 is FDA-approved to prevent smallpox. The U.S. is currently using only the Jynneos vaccine because it’s safer and has fewer side effects.

The Jynneos vaccine is safe. It has been tested in thousands of people, including people who are immunocompromised or have skin conditions. Common side effects of the Jynneos vaccine are similar to those of other vaccines and include fevers, fatigue, swollen glands, and irritation at the injection site.

The Jynneos vaccine is effective in preventing monkeypox disease up to four days after exposure and may reduce the severity of symptoms if given up to 14 days after exposure.

Q: Can I be vaccinated against monkeypox?

The Centers for Disease Control and Prevention currently recommends vaccination against smallpox and monkeypox only for those at heightened risk: people who have had close contact with someone with monkeypox, as well as some health care workers, laboratory staffers, first responders, and members of the military who might come into contact with the affected.

Supplies of the Jynneos vaccine are limited. As of June 14, the strategic national stockpile held more than 72,000 doses. The U.S. government purchased 500,000 more doses this month, bringing the total number of doses bought to almost 2 million.

The New York City Department of Health and Mental Hygiene has started offering the Jynneos vaccine to gay and bisexual men, other men who have sex with men, and trans women who are age 18 and older and have had multiple or anonymous sex partners in the past 14 days. Other big cities, including San Francisco, are expected to do the same.

Q: What are other ways to lower the risk of monkeypox transmission?

The best way is to educate yourself and your sex partners about monkeypox. If you’re worried you might have monkeypox, get tested at a sexual health clinic. Many emergency rooms, urgent care centers, and other health care facilities may not be up to date on monkeypox. The CDC link to find the nearest sexual health clinic is https://gettested.cdc.gov/.

Abstain from sex if you or your partner has monkeypox. And remember that condoms and dental dams can reduce but not eliminate the risk of transmission. The CDC also warns about the risk of going to raves or other parties where lots of people are wearing little clothing and of saunas and sex clubs. It has other suggestions like washing sex toys and bedding.

Q: Is there a treatment for monkeypox?

There is no proven, safe treatment specifically for monkeypox. Most cases of monkeypox are mild and improve without treatment over a couple of weeks. Medications like acetaminophen and ibuprofen can be used to reduce fevers and muscle aches, and medications like acetaminophen, ibuprofen, and opioids may be used for pain. In rare cases, some patients —such as immunocompromised people, pregnant women, a fetus or newborn, women who are breastfeeding, young children, and people with severe skin diseases — will develop more severe illness and may require more specific treatment. Doctors are trying experimental therapies like cidofovir, brincidofovir, tecovirimat, and vaccinia immune globulin. If administered early in the course of infection, the Jynneos and ACAM2000 vaccines may also help reduce the severity of disease.

Q: What misinformation is circulating about monkeypox?

Conspiracy theories about monkeypox abound. Monkeypox is not a hoax. Monkeypox is real. Covid vaccines can’t give you monkeypox. Monkeypox was not invented by Bill Gates or pharmaceutical companies. Monkeypox didn’t come from a lab in China or Ukraine. Migrants crossing the U.S.-Mexico border haven’t brought monkeypox into the U.S. Monkeypox isn’t a ploy to allow for mail-in ballots during elections. There is no need for a monkeypox vaccine mandate or lockdowns due to monkeypox.

Peel Region reports its first confirmed case of monkeypox – CP24 Toronto's Breaking News

Published

 on


Peel Region has its first confirmed case of monkeypox.

According to Peel Public Health, the person infected is an adult male in his 30s who lives in Mississauga.

The heath unit said the risk to the public remains low.

Monkeypox, which comes from the same virus family as smallpox, spreads though close contact with an infected individual. Most transmission happens through close contact with the skin lesions of monkeypox, but the virus can also be spread by large droplets or by sharing contaminated items.

To reduce risk of infection, people are advised to be cautious when engaging in intimate activities with others. Vaccination is available for high-risk contacts of cases and for those deemed at high risk of exposure to monkeypox.

Symptoms can include fever, headache, fatigue, swollen lymph nodes, and a rash/lesions, which could appear on the face or genitals and then spread to other areas.

Anyone who develops these symptoms should contact their healthcare provider and avoid close contact with others until they have improved and rash/lesions have healed.

While most people recover on their own without treatment, those who have been in close contact with someone who has tested positive for monkeypox should self-monitor for symptoms, and contact PPH to see if they are eligible for vaccination.

The Mississauga case is at least the 34th confirmed case of the disease in Ontario, with dozens more under investigation.
