Scientists around the world are racing to learn how to rapidly diagnose, treat and stop the spread of a new, deadly disease. SARS — Severe Acute Respiratory Syndrome — was detected for the first time in February in Hanoi, and since then has infected more than 1,600 people in 15 countries, killing 63. At this point, there are more questions than answers surrounding the disease.
Symptoms start with a fever over 100.4 degrees F, sometimes with chills, headache or body aches. Within a week, the patient has a dry cough, which might progress to shortness of breath. In 10% to 20% of cases, patients require mechanical ventilation to breathe. About 3.5% die from the disease.
