China Announces New SARS Case; WHO Calls for Urgent Investigation

China has announced its fourth confirmed SARS case of the season.

But it says the patient has made a "total recovery" and has already left the hospital.

That disclosure prompted a strongly worded statement from the World Health Organization calling for an urgent investigation.

The U.N. agency says it wasn't informed of the case until yesterday. And it says the case raises concerns "about the manner in which the man's infection was detected, treated and reported."

China's official news agency says the 40-year-old doctor fell ill on January seventh with a high fever, sore throat and fatigue. He checked himself into a hospital six days later and within five days, his condition had stabilized. The report says he was released from the hospital several days ago.

China was criticized for its sluggish, secretive response after the initial outbreak of SARS last year.
