Hundreds of guests and staff were under quarantine in China on Saturday after health officials determined that a hotel guest had contracted the H1N1 virus.
Next year, Professor John Oxford, an expert in virology from Queen Mary's School of Medicine and Dentistry, in London, will lock volunteers in a hotel for a week, deliberately infect some with the flu virus, and wait to see what happens.
Nearly 200 hotel guests and 100 staff members were ordered to stay in Metro Park Hotel in Hong Kong for seven days to stop the spread of the H1N1 virus, a government spokesman said.
