If there was another SARS outbreak, it should be possible to limit the spread of infection. SARS originated in China in It's thought that a strain of the coronavirus usually only found in small mammals mutated, enabling it to infect humans. There were also a small number of cases in several other countries, including 4 in the UK, plus a significant outbreak in Toronto, Canada.

The SARS pandemic was eventually brought under control in July , following a policy of isolating people suspected of having the condition and screening all passengers travelling by air from affected countries for signs of the infection. During the period of infection, there were 8, reported cases of SARS and deaths. This means the virus killed about 1 in 10 people who were infected.

People over the age of 65 were particularly at risk, with over half of those who died from the infection being in this age group. It was thought to have been the result of someone coming into direct contact with a sample of the SARS virus, rather than being caused by animal-to-human or human-to-human transmission.

Like all living things, viruses are constantly changing and evolving. A mutation is where the genetic information that's stored inside an organism changes. Many global outbreaks of infectious illnesses pandemics that have happened in recent history are thought to have been caused by viruses previously only found in animals.

After mutating, the viruses became capable of infecting humans. The SARS virus is spread in small droplets of saliva coughed or sneezed into the air by an infected person. In children, the virus' incubation period from exposure to infection is 2 to 7 days, although infection has taken as long as 10 days in some cases. However, not everyone exposed to the disease becomes ill. Scientists from around the world are collaborating to gain a better understanding of the cause of SARS.

SARS can be difficult to recognize in children because it mimics other respiratory diseases, such as influenza. It generally begins with a fever higher than There is currently no test to diagnose SARS.

The symptoms of SARS may look like other medical conditions. Always consult your child's health care provider for a diagnosis. When a person with SARS coughs or sneezes without covering his or her mouth, respiratory droplets containing living virus can spray up to 3 feet and invade the mucous membranes of another person. People in close contact with someone with SARS are most at risk, which means they live or work with someone with SARS or have direct contact with the person through kissing, hugging, or sharing eating utensils.

The virus also can spread when a child touches an object with infectious droplets on it and then touches his or her mouth, nose, or eyes. It is not known whether SARS can spread more broadly through the air. Research suggests that children with SARS are infectious only when they are having symptoms, such as fever or cough. They are most infectious during their second week of illness. March The SARs outbreak is more widespread. CDC quarantine staff began meeting planes, cargo ships and cruise ships coming either directly or indirectly to the United States from China, Singapore and Vietnam and also begins distributing health alert cards to travelers.

April 4: The number of suspected U. SARS cases was ; reported from 29 states. Identifying the genetic sequence of a new virus is important to treatment and prevention efforts. The results came just 12 days after a team of scientists and technicians began working around the clock to grow cells taken from the throat culture of a SARS patient.

May 6: In the United States, no new probable cases were reported in the last 24 hours, and there was no evidence of ongoing transmission beyond the initial case reports in travelers for more than 20 days. The containment in the United States has been successful. May CDC lifted the travel alert on Toronto because more than 30 days or three SARS incubation periods had elapsed since the date of onset of symptoms for the last reported case.

June 4: CDC removed the travel alert for Singapore and downgraded the traveler notification for Hong Kong from a travel advisory to a travel alert. The change results from excluding cases in which blood specimens that were collected more than 21 days after the onset of illness test negative.
