    H1N1 Flu of 2009 in Canada

    From April to December 2009, Canada experienced an outbreak of influenza A (H1N1). The virus began in North America and spread to many other countries in a global pandemic. This new type of flu differed from the typical seasonal flu, and its effects were more severe. Worldwide, more than 18,000 people are confirmed to have died of H1N1, including 428 Canadians. Estimates based on statistical models have put global deaths much higher. Totals may have been in the hundreds of thousands. The H1N1 pandemic tested Canada’s improvements to its public health system after the SARS outbreak of 2003. On the whole, it revealed a more efficient, coordinated response.

    E. coli Infection in Canada

    Every year, approximately 470 Canadians are infected with E. coli bacteria, which can cause severe illness and, in a small minority of cases, death. Though the illness has been called “hamburger disease,” based on its association with ground beef patties containing infection-causing E. coli, it can be transmitted through a variety of other foods, untreated water and contact with the fecal matter of infected people and animals. Several deadly, high-profile E. coli outbreaks have occurred in Canada since the 1980s. They have resulted in greater public awareness, as well as changes in regulations and health practices.
