What is the cau of SARS? SARS is caud by a previously unrecognized coronavirus, called SARS-associated coronavirus (SARS-CoV). It is possible that other infectious agents might have a role in some cas of SARS.
How is SARS spread?The primary way that SARS appears to spread is by clo person-to-person contact. SARS-CoV is thought to be transmitted most readily by respiratory droplets (droplet spread) produced when an infected person coughs or sneezes. Droplet spread can happen when droplets from the cough or sneeze of an infected person are propelled a short distance (generally up to 3 feet) through the air and deposited on the mucous membranes of the mouth, no, or eyes of persons who are nearby. The virus also can spread when a person touches a surface or object contaminated with infectious droplets and then touches his or her mouth, no, or eye(s). In addition, it is possible that SARS-CoV might be spread more broadly through the air (airborne spread) or by other ways that are not now known.
What does "clo contact" mean?Clo contact is defined as having cared for or lived with a person known to have SARS or having a high likelihood of direct contact with respiratory cretions and/or body fluids of a patient known to have SARS. Examples include kissing or embracing, sharing eating or drinking utensils, clo conversation (within 3 feet), physical examination, and any other direct physical contact between people. Clo contact does not include activities such as walking by a person or briefly sitting across a waiting room or office.
If I were expod to SARS-CoV, how long would it take for me to become sick?The time between exposure to SARS-CoV and the ont of symptoms is called the "incubation period." The incubation period for SARS is typically 2 to 7 days, although in some cas it may be as long as 10 days. In a very small proportion of cas, incubation periods of up to 14 days have been reported.
口语一百How long is a person with SARS infectious to others? Available information suggests that persons with SARS are most likely to be contagious only when they have symptoms, suc
h as fever or cough. Patients are most contagious during the cond week of illness. However, as a precaution against spreading the dia, CDC recommends that persons with SARS limit their interactions outside the home (for example, by not going to work or to school) until 10 days after their fever has gone away and their respiratory (breathing) symptoms have gotten better.
Is a person with SARS contagious before symptoms appear?To date, no cas of SARS have been reported among persons who were expod to a SARS patient before the ont of the patient's symptoms.
What medical treatment is recommended for patients with SARS? CDC recommends that patients with SARS receive the same treatment that would be ud for a patient with any rious community-acquired atypical pneumonia. SARS-CoV is being tested against various antiviral drugs to e if an effective treatment can be found.雌蟒
