Close contact does not include activities such as walking by a person or briefly sitting across a waiting room or office. Examples include kissing or embracing, sharing eating or drinking utensils, close conversation (within 3 feet), physical examination, and any other direct physical contact between people. What does “close contact” mean?Ĭlose 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 secretions and/or body fluids of a patient known to have SARS. 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. The virus also can spread when a person touches a surface or object contaminated with infectious droplets and then touches his or her mouth, nose, or eye(s). 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, nose, or eyes of persons who are nearby. SARS-CoV is thought to be transmitted most readily by respiratory droplets (droplet spread) produced when an infected person coughs or sneezes. The primary way that SARS appears to spread is by close person-to-person contact. It is possible that other infectious agents might have a role in some cases of SARS. SARS is caused by a previously unrecognized coronavirus, called SARS-associated coronavirus (SARS-CoV). In 10 percent to 20 percent of cases, patients require mechanical ventilation. After 2 to 7 days, SARS patients may develop a dry, nonproductive cough that might be accompanied by or progress to a condition in which the oxygen levels in the blood are low (hypoxia). Diarrhea is seen in approximately 10 percent to 20 percent of patients. Some people also experience mild respiratory symptoms at the outset. The fever is sometimes associated with chills or other symptoms, including headache, general feeling of discomfort, and body aches. The illness usually begins with a high fever (measured temperature greater than 100.4☏ ). Severe acute respiratory syndrome (SARS) is a viral respiratory illness that was recognized as a global threat in March 2003, after first appearing in Southern China in November 2002.
