As if we didn't have enough to think about, we now have a newly discovered respiratory disease that is considered serious enough to unite the world community in an effort to fight and defeat this potential killer. Its name is SARS (severe acute respiratory syndrome), and it's making a medical and economic impact worldwide.
As of April 21, 2003, there have been more than 4,000 cases of SARS and 217 deaths reported worldwide. In the United States, there are at least 220 suspected cases and, fortunately, no deaths.
What Is SARS?
Unfortunately, we don't know a lot about SARS — yet. It's still being identified, but here's what we do know: SARS was first reported sometime after Feb. 1, 2003, in Guangdong province (China), Hanoi (Vietnam) and Hong Kong.
Concerned that this mysterious illness could spread to other parts of the world, health authorities in Singapore notified the World Health Organization (WHO). Within hours, WHO declared a worldwide emergency travel advisory, which stated that SARS was a global health threat.
What's Causing SARS?
Scientists have determined that SARS is caused by a new form of the coronavirus never before seen in humans. The identification of the virus means that scientists can now begin working on a vaccine to control and/or eradicate the virus.
Top laboratories — including the Centers for Disease Control and Prevention (CDC) — in eight different countries have been working round the clock to get a handle on the virus. WHO is collecting the information and connecting specialists worldwide via a daily conference call. There's truly a global effort to help control and treat the disease.
How Is SARS Diagnosed?
If we didn't know about the potential danger of SARS, we might put it into a "flu-like" illness category. However, there are notable differences with SARS, including shortness of breath and low oxygen levels in the blood.
SARS is characterized by a temperature of more than 100.5 degrees Fahrenheit, combined with one or more of the following:
- dry cough
- shortness of breath
- difficulty breathing
- low-blood oxygen levels
- an X-ray that shows either pneumonia or some type of respiratory-distress ailment
- Travel (within 10 days of symptoms) to mainland China, Hong Kong, Hanoi or Singapore
- Close contact (within 10 days of illness) with someone who has traveled to a SARS area, or who is suspected of having SARS.
To date, there is no approved test to diagnose SARS. However, the CDC, along with some other labs, is getting closer to developing a test that identifies the culprit virus.
Who's at Risk for SARS?
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."
