Like many others, you've probably wondered about the long term effects of COVID-19.

You may have even heard of people who have symptoms weeks, or even months, after testing positive.

Recently, a University of British Columbia study showed that up to 76% of COVID-19 patients report lasting health effects.

However, one expert suggests that Ontarians don't need to worry about this just yet.

Narcity spoke to Dr. Angela Cheung, a senior scientist at Toronto General Hospital Research Institute researching long-term effects on COVID-19 patients.

Cheung compared the lasting effects of COVID-19 to the ones seen in SARS or pneumonia.

"We often see some patchy abnormalities," she said, "from three weeks to six months [after contraction,] and we see minimal or mild fibrotic changes, but they're not really of any clinical significance."

Cheung says that a study done cross-country with a large number of participants would be needed to draw any conclusive evidence.

She admits that lingering symptoms from respiratory illnesses like COVID-19 aren't unusual.

"The reason we do research is not just to understand [COVID-19], but also see if we can find solutions as well, so that we can help people feel better and recover," said Cheung.
