How does SARS spread?
• Large droplet aerolization – This is the most common means of spread. This means that most people who catch SARS, do so by close contact with those who are infected and coughing (coughing causes aerolization). • Contact with infected objects – The SARS virus may live outside the body for up to a few days. Some people appear to have been infected by coming into contact with objects (particularly sewage). The virus would get onto the hand, and would typically enter the body upon touching the eyes or nose. • Airborne transmission – It is possible, but not yet shown to be the case, that the SARS virus may rarely infect those who have not come into close contact with SARS patients. If this is the case, then it is possible that SARS might be able to spread through vents and ducts in a building.
