Canada might officially be flattening the curve and slowing the spread of COVID-19, according to Chief Public Health Officer Dr. Theresa Tam.

Speaking on Wednesday, Tam said, "there is cause for some cautious optimism from our epidemiological data."

According to Tam, the number of COVID-19 cases has gone from doubling over three days to doubling over 10 days, indicating that Canada is successfully flattening the curve.

Dr Tam says there is some reason for cautious optimism. The number of cases has gone from doubling over three days to doubling over TEN days.

"This means the epidemic is slowing down," she said.

The case numbers were increasing exponentially in late March, but have recently showed signs of levelling off due to social distancing measures in Canada.

However, Tam warned Canadians that the decline in case numbers isn't a cause for celebration just yet.

"We all wish this could be a sprint to the finish line," she said, "but it's a marathon, and there are no rewards for quitting early."

"Coming down from this epidemic curve will be like making our way down from a mountain in the darkness; we must not rush or let go of our safety measures, or the fall will be hard and unforgiving."
