CALGARY -- Alberta is just weeks away from ending its indoor mandatory mask rule, but one Calgary doctor is hoping people consider wearing one, even after all pandemic rules are lifted. Dr. Eddy Lang is an emergency doctor and is the co-author of a study that looked into hospitalizations unrelated to COVID-19 during the first months of the pandemic compared to the previous year. It found the public health measures meant to slow the spread of COVID-19 also worked in reducing the amount of Albertans needing to be rushed to hospital. "What we saw was a 30 per cent reduction in hospitalizations for chronic lung disease due to smoking, called COPD, as well as pneumonia, which are also common, which were not related to COVID," said Dr. Lang, who is also with the University of Calgary's Cumming School of Medicine.
