Singapore health officials say a man has tested positive for the SARS virus.
Singapore doctors say initial tests show a male patient is infected with the virus that causes Severe Acute Respiratory Syndrome. They caution that initial tests can be false alarms and are planning more tests to confirm their diagnosis.
Singapore health officials describe the man as ethnic Chinese, and say he has been isolated for treatment. They have not said whether or not he is a citizen of Singapore.
If the infection is confirmed, it would be the first SARS case in Singapore since early May, when the World Health Organization declared the city-state free of the disease.
