10,000 To Be Screened in Hong Kong For SARS Exposure

Scientists in Hong Kong are planning to screen 10,000 citizens to find out how many may have been infected with SARS without realising it.

The researchers will be looking for antibodies in the bloodstream to SARS, indicating that a person has previously been infected and has since cleared the virus from their body.

By studying people like this, who have naturally fought off SARS without becoming seriously unwell, the researchers are hoping to learn why the infection is more severe in some people than others, and possibly find new ways to prevent or treat it.
