These factors could include the type of material or body fluid containing the virus and various environmental conditions such as temperature or humidity.

Researchers at CDC and other institutions are designing standardized experiments to measure how long SARS-CoV can survive in situations that simulate natural environmental conditions.

PCR or polymerase chain reaction is a laboratory method for detecting the genetic material of an infectious disease agent in specimens from patients. This type of testing has become an essential tool for detecting infectious disease agents.

For a viral culture, a small sample of tissue or fluid that may be infected is placed in a container along with cells in which the virus can grow. If the virus grows in the culture, it will cause changes in the cells that can be seen under a microscope.

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. To help prevent spread from suspected cases, health care practitioners should use standard, contact, and airborne precautions.

SARS is much more severe than other coronavirus infections. SARS is an influenza-like illness that occasionally leads to progressively severe respiratory insufficiency. This outbreak subsided, and no new cases have been identified since The immediate source was presumed to be civet cats, that were being sold for food in a live-animal market and had likely been infected through contact with a bat before they were captured for sale.

Bats are frequent hosts of coronaviruses. It is thought to be transmitted most readily by respiratory droplets produced when an infected person coughs or sneezes. Diagnosis of SARS is made clinically, and treatment is supportive. Coordination of prompt and rigid infection control practices helped control the outbreak rapidly. Although no new cases have been reported since , SARS should not be considered eliminated because the causative virus has an animal reservoir from which it conceivably could reemerge.
