Answer 1

Answer:

Severe acute respiratory syndrome (SARS) is a viral respiratory illness that first emerged in China in November 2002, and later spread through international travel to 29 countries worldwide causing large outbreaks in Hong Kong; Taiwan; Singapore; Hanoi, Vietnam; and Toronto, Canada. According to the World Health Organization (WHO), from November 2002 to July 31, 2003, there were 8,098 cases of SARS; of these, 774 died.

On October 1, 2003, the Centers for Disease Control and Prevention (CDC), reported that there were 164 probable and suspect SARS cases in the United States, of which only eight had laboratory evidence of SARS. There were no deaths due to SARS in the US. Most of the U.S. SARS cases were among travelers returning from other parts of the world with SARS. There were 11 suspect and probable SARS cases investigated by the Minnesota Department of Health; many of these individuals had an alternative diagnosis that could explain their symptoms.

Severe acute respiratory syndrome (SARS) is a viral respiratory illness that first emerged in China in November 2002, and later spread through international travel to 29 countries worldwide causing large outbreaks in Hong Kong; Taiwan; Singapore; Hanoi, Vietnam; and Toronto, Canada. According to the World Health Organization (WHO), from November 2002 to July 31, 2003, there were 8,098 cases of SARS; of these, 774 died.

SARS is caused by a virus called the SARS-associated coronavirus (SARS-CoV). It was first identified in April 2003 and is a member of the Coronaviridae family, which also includes many of the viruses that cause the common cold. Coronaviruses have been found in many different animal species including birds and mammals. SARS-CoV is thought to have passed from animals to humans through close contact, butchering or eating undercooked meat in parts of Southern China.

SARS is spread primarily by close person-to-person contact. In the context of SARS, close contact means having cared for or lived with someone with SARS or having direct contact with respiratory secretions or body fluids of a patient with SARS.

The virus that causes SARS is transmitted by the spread of respiratory droplets produced when an infected person coughs or sneezes.

When a person coughs or sneezes, small amounts of fluid are propelled for about 3 feet through the air and land on the mouth, nose or eyes of persons who are near by.

The virus also can spread when a person touches a surface or object contaminated with these infectious droplets and then touches his or her mouth, nose, or eyes.

It is possible that the SARS virus might spread more broadly through the air (airborne spread) or by other ways t
