Severe acute respiratory syndrome (SARS) is a respiratory infection caused by the SARS-associated coronavirus (SARS-CoV), whose natural reservoir is the Chinese horseshoe bat. Initial manifestations of SARS include fever greater than 100.4 °F (38 °C) with or without chills/rigors, malaise, and a dry, nonproductive cough. Infection with SARS-CoV can progress rapidly to pneumonia, acute respiratory distress, and death. The SARS-CoV is robust and has been found to survive on the hands and on common surfaces (e.g., tabletops, doorknobs) for several hours, on personal protective equipment (PPE) and scrubs for up to 24 hours, and in the stools of persons with SARS for up to 4 days. The first signs and symptoms of SARS—fever, malaise, and nonproductive cough—typically begin 2–7 days after exposure to the virus, but the incubation period for SARS can be up to 10 days. Affected individuals are most contagious during the second week of illness. SARS is highly transmissible through close personal contact (e.g., being within 3 feet of another person) by kissing, sharing utensils, coughing, and sneezing, which results in droplet transmission.
