Hong Kong investigates SARS relapses
The SARS virus may be more serious than first thought, with Hong Kong medical authorities investigating the relapse of 12 previously recovered patients.
Health authorities in Hong Kong thought the 12 SARS victims had recovered, and released them from hospital.
But doctors are now investigating whether the virus is more durable than first thought, after the 12 suffered relapses.
Six people are said to be in stable conditions, while the remaining six have again been released.
The SARS outbreak is believed to be coming under increasing control in Hong Kong.
Relapsing patients could again see widespread infections happening in the community.
