Severe Acute Respiratory Syndrome (SARS) is an acute respiratory illness caused by infection with the SARS virus. The WHO estimates that the case fatality ratio of SARS ranges from 0% to 50% depending on the age group affected. The virus is predominantly spread by droplets or by direct and indirect contact. Medical personnel, physicians, nurses, and hospital workers are among those commonly infected. In the absence of effective drugs or a vaccine for SARS, control of this disease relies on the rapid identification of cases and their appropriate management, and the management of their close contacts. At present, the most efficacious treatment regimen for SARS is still subject to debate.
