Severe Acute Respiratory Syndrome

Researchers in Hong Kong have identified chemicals that may prevent the virus from replicating once it infects a human body. Other researchers are investigating if genetically engineered antibodies are effective in blocking the virus. In addition, efforts to develop a vaccine that would prevent SARS are underway.

Until effective treatments can be developed, public-health officials have established infection-control measures to contain the spread of SARS. Those people diagnosed with SARS or suspected of having the illness are treated in isolation in their homes, in hospitals, or in other designated health-care settings. Caregivers follow strict procedures to lessen their own risk of infection. The WHO also issues travel advisories recommending against nonessential travel to certain countries where the risk of infection is high.
