The National Institute for Health and Care Excellence (NICE) has warned that there is a “risk” of developing an infection in Canadians who have been in the intensive care unit for up to 24 hours.
A review published in the journal BMJ Open has found that nearly half of the study participants had a high fever, more than a third had a headache and more than half had chest pain.
The NICE has recommended people who have not recovered from their illness for at least 24 hours not to consume alcohol or use painkillers, and to not consume any foods that could make them more likely to contract the illness.
“If you’ve been out for 24 hours, you may be at risk for having an infection, even if you’ve had no symptoms,” Dr Stephen Burdett, the lead author of the review, said in a statement.
“But if you have symptoms, we’re warning you to stay home, to abstain from all foods and drinks, and not to use them.”
Dr Burdets said the majority of people who had recovered from a bout would recover without getting sick again.
“What this study shows is that there are a number of factors that increase the risk of developing a complication in the long term.
People who have recovered from acute COVID-19 can experience an increase in their risk of a complication, including increased risk of infection,” he said.
The study was carried out in the province of Quebec, where there are around 3.5 million people who are infected with the coronavirus.
In response to the NICE report, the Ontario government issued an emergency order to limit the number of people admitted to the ICU.
It said there was “no scientific evidence that acute COVI-19 infection leads to long-term complications”.
“The health care system is not equipped to deal with the complexities of managing the effects of a virus outbreak,” the order read.
“The Ontario Government has issued an Emergency Order, which restricts the number admitted to ICU due to acute COV-19.”
The National Centre for Chronic Disease Prevention and Health Promotion said that although the study showed that people who recovered from COVID infections had a lower risk of contracting the virus, they still needed to be cautious.
“While it is important to stay healthy and prevent long-lasting illness, it is also important to remember that any person can be infected with COVID and potentially die,” Dr Jaijendra Bhandari, the Centre’s chief medical officer, said.
“So people who recover from acute viral infections have to be vigilant and take care to maintain their levels of immunisation.”
The Centre is also urging people to limit their outdoor activity, including swimming and boating.
“Exercise is important, but the risk for COVID is even higher if you are exposed to water,” Dr Bhandaris said.
Dr Bhandaridis said it was also important for people to be aware of their healthcare provider’s advice on how to best manage their health.
“There is no single answer,” he told AAP.
“It is up to each individual and individual is unique.
If someone is feeling unwell and is concerned about COVID, that’s something to talk to their healthcare team.”
Some people can get sick if they get too hot, others can get very cold.
We have to manage that.
