Researchers say they have discovered new evidence suggesting that the virus that causes Severe Acute Respiratory Syndrome could, in some circumstances, spread through the air.
The research, published in the New England Journal of Medicine, focused on an unusual SARS outbreak last year at Hong Kong's Amoy Gardens apartments. More than 300 people contracted the disease in the multi-building complex.
Researchers say it appears the virus infected so many residents by traveling through one building's air shaft before being carried to neighboring buildings.
Researchers say the new evidence suggests that the SARS virus could be transmitted more easily than previously believed.
The SARS outbreak, which emerged in southern China, infected more than 8,000 people in dozens of countries and killed more than 900.
