Mysterious Virus Emerges in the Middle East
Global health authorities are hunting for cases of a mysterious viral respiratory illness that killed at least one person in Saudi Arabia and left another who traveled there in intensive care in a U.K. hospital.
Health officials said the source of the virus infecting both is unknown, though they have identified it as a coronavirus, part of a large family of viruses that in most cases cause common colds, but also have caused SARS.
Severe acute respiratory syndrome erupted in China in late 2002 and spread to a number of countries, infecting more than 8,000 people and killing about 775 before it disappeared in mid 2003.
