Snippet: Abstract The original coronavirus disease (COVID-19) outbreak in Wuhan, China has become a global pandemic. By tracking the earliest 118 COVID-19 cases in Canada, we produced a Voronoi treemap to show the travel origins of the country’s earliest COVID-19 cases. By March 11, 2020, even though the majority (64.1%) of the world’s COVID-19 confirmed cases still had their origin in China, only 7.6% of Canada’s first 118 COVID-19 cases arose due in travelers to China. The most commonly reported
Document: Abstract The original coronavirus disease (COVID-19) outbreak in Wuhan, China has become a global pandemic. By tracking the earliest 118 COVID-19 cases in Canada, we produced a Voronoi treemap to show the travel origins of the country’s earliest COVID-19 cases. By March 11, 2020, even though the majority (64.1%) of the world’s COVID-19 confirmed cases still had their origin in China, only 7.6% of Canada’s first 118 COVID-19 cases arose due in travelers to China. The most commonly reported travel history among the 118 cases originated from the Middle East, the United States, and Europe. Thus, in retrospect, broadening of early screening tools and travel restrictions to countries and regions outside China may help control global COVID-19 spread.
