A 27-year-old researcher is recovering after having been diagnosed last week with SARS. He is believed to have caught the potentially fatal disease in a laboratory where he worked, and where work on SARS was done.Singapore's health ministry said an 11-member panel to investigate the case was being chaired by Antony Della-Porta, an Australian biosafety expert with the World Health Organization.
The U.S. Centers for Disease Control and Prevention in Atlanta also provided two experts to help with the investigation.
"The international experts on the panel started work today and have visited some of the laboratories," the ministry said in a statement. The panel is expected to finish its work next week.
Flu-like SARS is believed to have originated in China late last year. It infected nearly 8,500 people around the world and killed more than 800, most of them in Asia.
The WHO declared the end of the global outbreak in July.
Twenty-five people who came into contact with the Singapore researcher were quarantined at home although none has symptoms of Severe Acute Respiratory Syndrome, the ministry said.
