Among the main emergency response problems during the SARS crisis in Toronto, the following can be mentioned: Although Health Canada was aware of the spread of atypical pneumonia in Asia, and despite the massive arrival in Toronto Airport with passengers from the Far East, no measures have been taken to monitor these arriving passengers or to alert the medical service of the risk of having to treat patients with the mentioned disease. (VARLEY, 2005)Not having the proper information, Scarborough-Grace Emergency after being searched by Tse Chi Kwai - a 43-year-old man who, in just a few days, had lost his mother to what was primarily diagnosed as a flu - ; whose symptoms were fever, tremors, difficulty breathing and cough; proceeded to his hospitalization in the emergency room, near many other patients. Additionally, demonstrating Toronto's unpreparedness to deal with the new disease, Mr. Kwai's breathing difficulties were alleviated by the use of BiPAP, recently recognized as responsible for the more serious spread of the infectious virus. (VARLEY, 2005) At that time, even if the disease had not yet been given a name and its true severity was not fully known, health professionals should have been alerted to the possibility of being confronted with infected patients and treat any suspected cases. with all the precautions that a highly contagious disease implies, for example isolating the patient. Faced with SARS, Toronto's emergency medical system proceeded without necessary precautions; once his professional has not even considered the possibility of being in contact with a dangerous and unknown infectious disease. The lack of information, in addition to endangering other patients seeking medical care, also endangered the health of doctors, nurses and other medical assistants. Accustomed to treating infectious diseases without proper protective equipment, such as gloves, goggles, gowns and masks, medical staff treated Tse and other SARS-infected patients without any precautions. The careless procedure mentioned contributed to the infection of many healthcare professionals and the consequent spread of the disease in Toronto. In the midst of the SARS crisis, it became clear that there was considerable confusion over who was actually responsible for overcoming the SARS crisis. crises and what was the exact attribution of each department involved. Weak synergy between Toronto Public Health (THP) and the Ontario Ministry of Public Health contributed to poor tracking of people potentially infected with SARS and the uncontrolled spread of the disease..
