OHSWEKEN — Six Nations Health Services says residents who have contracted COVID-19 are reporting long lasting symptoms that continue even after their illness has resolved.
According to a Post-COVID-19 Symptom Survey, respondents reported that 62% of people who have overcome the initial illness are still experiencing long-COVID symptoms.
The most common symptoms reported include: 55% reporting brain fog and difficulty concentrating; 46% reporting fatigue, and loss of taste and smell; and 36% reported breathlessness.
The Ontario COVID-19 Science Advisory Table, a group that provides guidance to the province on the pandemic, said the post-COVID-19 symptoms affect about 10 per cent of those infected and can last from weeks to months.
“There is under-recognition both for the public but also among clinicians of this condition because it is hard to define and quantify and because we don’t have a lot of information around it,” said Fahad Razak, the lead author of the report.
A conservative estimate suggests about 150,000 Canadians who contract the novel coronavirus experience long COVID-19 symptoms, Razak said. In Ontario, between 57,000 and 78,000 people are affected.
The most common of more than 200 different symptoms include fatigue, shortness of breath, general pain or discomfort, anxiety and depression.
Razak said individuals experiencing such symptoms have difficulty performing daily activities and require increased health-care resources.
“The burden will not only be on the health system, it will also be on other parts of society because a lot of the disabilities are not just about medical care, it’s about the fact that individuals can’t go back to work, it’s that they need a supportive home, it’s difficulty with work and family life,” he added.
The World Health Organization has reported that approximately one in four individuals who were infected with the virus experience symptoms of long COVID for at least one month. Meanwhile, one in 10 people experience symptoms that last beyond 12 weeks.
The Ontario science advisory group said more research is needed on risk factors for long COVID. Vaccination reduces the chance of developing the post-COVID-19 condition, Razak said.
To date, nearly 84.5 per cent of Ontarians over the age of 12 have received one dose of a COVID-19 vaccine and 78.2 per cent have two doses.
Razak said the latest report from the science advisory group looked at data from the earlier waves of the pandemic and did not take variants of the virus — like Delta and Alpha — into account.
“We don’t have the data yet to know the impact,” he said. “The worry is that those variants are clearly more infectious so we’re potentially running into a problem where we’re going to see even higher rates of the post-COVID condition.”
There is limited Canadian data on health-care use patterns for patients with long COVID, including emergency department visits and hospital admissions, the science group said. A pan-Canadian study is currently being done to examine these patterns for long COVID-19 patients.
SNHS says this is the first wave of the survey regarding Six Nations resolved cases and are looking for more people who have overcome COVID to respond. Details on how to participate can be found on the Healthy 6Nay Facebook page.
