Who's at risk for severe acute respiratory syndrome (SARS) transmitted?

According to the CDC, "cases of SARS continue to be reported primarily among persons who have had direct close contact with an infected person. "Close contact" is defined by "anyone who has cared for, lived with, or had direct contact with

respiratory droplets such as mucous, or body fluids of a patient suspected or known to have SARS."

Based on currently available information, the risk factors are one of more of the following:

  • Close contact within the previous 10 days with a probable case of SARS
  • Recent travel within the previous 10 days to a WHO reported "affected area" in Asia.
  • Recent travel or visit within the previous 10 days to a defined setting that is associated with a cluster of SARS cases (e.g., hospital)

Doctors and hospital workers who treated SARS patients before the disease was identified were some of the first SARS casualties. But stringent guidelines - including the use of gowns, gloves, goggles and N95 masks, which block 95 percent of non-oily, solid and liquid particles - are now in place to help protect health care professionals from infection.

Researchers also have identified a variation in an immune system gene that seems to make people with the variation much more vulnerable to the SARS virus. The genetic variation is common among people of southern Chinese descent but rare in other populations, which may help explain why most SARS cases have occurred in China and Southeast Asia.
