There is mounting research of long-term effects of COVID 19, but there's still much more to learn.
In the short time it has been affecting people, some survivors are reporting health problems after they've recovered.
Dr. Wassim Saad says recovery is divided into two groups, those who have mild symptoms and require little treatment and those who find themselves in the ICU. The chief of staff at Windsor Regional Hospital spoke with Patty Handysides on The Afternoon News.
Continuing symptoms such as" headache, chronic fever, lung disease and fatigue" for those who recovered at home are a growing concern, according to Saad.
He says ICU patients will experience those symptoms with the addition of physical and psychological impairments or, "brain fog."
"There's lost time there in an ICU where you're intubated and your sedated, in a medical inducted coma," says Saad. "Whenever you have that lost time the brain starts to fill in that time with whatever it thinks it can fill it in with."
He says there's one consistent symptom that continues to pop up for all patients.
"I've looked after a couple of patients who've been in hospital, one was in the ICU and one was not and both of them report significant fatigue - we're seeing this in the medical literature as well," he added.
Dr. Saad says medical professionals saw similar recovery issues in SARS patients, a strain of coronavirus that hit Toronto in 2003.
