Definition
Severe acute respiratory syndrome (SARS) is a contagious and sometimes fatal respiratory illness. SARS first appeared in China in November 2002. Within a few months, SARS spread worldwide, carried by unsuspecting travelers. SARS showed how quickly infection can spread in a highly mobile and interconnected world. The SARS epidemic also demonstrated that international cooperation among health experts can effectively contain the spread of the disease. Since 2004, known instances of SARS transmission have fallen to zero worldwide. Symptoms

SARS typically begins with flu-like signs and symptoms — fever, chills, muscle aches and occasionally diarrhea. After about a week, signs and symptoms include: * Fever of 100.4 F (38 C) or higher

* Dry cough
* Shortness of breath
When to see a doctor 
If you think you've been exposed to or have SARS, see your doctor right away. SARS is a serious illness that can lead to death. Causes
SARS is caused by a strain of coronavirus, the same family of viruses that causes the common cold. Until now, these viruses have never been particularly dangerous in humans, although they can cause severe disease in animals. For that reason, scientists originally thought that the SARS virus might have crossed from animals to humans. It now seems likely that it evolved from one or more animal viruses into a completely new strain. How SARS spreads 

Most respiratory illnesses, including SARS, spread through droplets that enter the air when someone with the disease coughs, sneezes or talks. Most experts think SARS spreads mainly through face-to-face contact, but the virus also may be spread on contaminated objects — such as doorknobs, telephones and elevator buttons. Risk factors

In general, people at greatest risk of SARS have had direct, close contact with someone who's infected, such as family members and health care workers. Complications
Most people with SARS develop pneumonia. Breathing problems can become so severe that...
