Is there light at the end of the tunnel? We might not be out of the woods yet but there's still hope to be found. Dr. Theresa Tam has "cautious optimism" when it comes to COVID-19 in Canada. Even though there are positive signs, there's still work that needs to be done when it comes to fighting this epidemic.\nOn April 15, Dr. Tam took to Twitter to share information about the virus and how efforts by Canadians are helping to slow the spread.\nIn a thread, she said that while we don't have all the answers about COVID-19 yet, "there is some cause for cautious optimism" based on data.\nShe went on to mention that the growth rate of the virus in Canada was at its fastest in March.\nDuring that time, the number of new cases was doubling every three days.\nNow, in recent days, that doubling time has shifted to over 10 days which Dr. Tam said means the epidemic is slowing down.\nHowever, this optimism doesn't mean that we can all relax now — more still needs to be done.\n"Though we all wish this could be a sprint to the finish, it is NOT," Dr. Tam said. "This will be a MARATHON and there are no rewards for quitting early."\n3/10 At this point, we still don’t have all the answers, but there is some cause for cautious optimism coming from our epidemiological data. #COVID19 #COVIDCoping #WeWillGetThroughThis #cavabienaller— Dr. Theresa Tam (@CPHO_Canada) April 15, 2020\n5/10 In late March, when the #COVID19 growth rate was fastest, we saw case numbers doubling every 3 days, but in recent days we’ve observed a doubling time of over 10 days. This means the epidemic is slowing down. pic.twitter.com/OpOAn7Uxzq— Dr. Theresa Tam (@CPHO_Canada) April 15, 2020\nDuring a press conference on April 16, Dr. Tam also addressed that cautious optimism but still stressed that there's more to do.\n"There are signs our collective efforts starting several weeks back have had an effect to slow down the epidemic," she said.\nShe went on to note that the recent long weekend, or "staycation for the nation" as she put it, may have helped maintain that trend.\n"We now need to double down to stamp out outbreaks in high-risk settings," she said.\nIf action isn't taken, there could be more outbreaks and more deaths related to COVID-19.\n"Without immediate action there will be more outbreaks": Canada's chief public health officer, Dr. Theresa Tam, says the pandemic has revealed flaws in the health-care system among vulnerable groups.
