China has reported more infections from a new virus than it had from an outbreak of SARS in 2002-2003, although the death toll is still lower.
China said it has confirmed 5,974 cases of the new virus, compared to 5,327 cases of SARS.
It also reported another large jump in cases on Wednesday and a rise in the death toll to 132. That compares to 348 people killed in China during SARS. Severe acute respiratory syndrome killed nearly 800 people worldwide.
Scientists say there are still many critical questions to be answered about the new virus, including just how transmissible and severe it is. More than 50 cases have been reported outside China.
