SARS is caused by a specific group of viruses. The viruses are spread from droplets in the air. The droplets come from spray when a sick person sneezes or coughs. Viruses can also be picked up from objects that an ill person has touched.
Factors that may increase your chance of developing SARS include: Gene variation in the immune system—This gene variation may be more common in people in Southeast Asia. The variation makes people more susceptible to developing SARS.Recent travel to locations in Asia where SARS outbreaks have been reported.Close contact with someone who has SARS.Healthcare workers who care for patients with SARS.
SARS requires care from your doctor. If you suspect you have this condition, contact your doctor right away.

There are currently no medications to treat or cure SARS. Viral infections cannot be treated with antibiotics and current antiviral drugs have not had any effect.
Researchers are looking for ways to shorten the course and severity of the infection with: CorticosteroidsMedications that suppress or enhance the immune system
The symptoms of SARS will be treated with oxygen therapy if it is needed. If you are having difficulty breathing, you may be given oxygen through a tube or mask. More severe problems may require a machine to help you breathe.
To help reduce your chance of getting SARS, take these steps:
proper hand washing
Regularly use alcohol-based hand sanitizers.Disinfect toilets, sinks, or other objects or surfaces used by anyone with SARS.Do not share utensils, glasses, towels, or linen with anyone with SARS.If you are a healthcare worker, use gloves, a gown, and eye protection when caring for patients with SARS.
