The virus seems to spread through aerosolized (exhaled) droplets and body secretions from an infected person. You can come into contact with these droplets when an infected person coughs or sneezes. So far, most cases in Canada have occurred with people who have recently travelled to Asia, health care workers who have cared for SARS patients, and close family members of SARS patients. The incubation period (the amount of time it takes for symptoms to appear after exposure to the virus) usually takes 2 to 7 days, but may take as long as 10 days.
