BEIJING – Beijing's records on SARS (search) cases have serious flaws because the information is so incomplete it does not show how half of the city's patients caught the highly contagious respiratory illness, the World Health Organization (search) said Saturday.
WHO also warned that SARS has become more serious in the Taiwanese capital of Taipei (search) because officials can't track down the infection source for a high number of people -- the latest sign that the island was losing control of the outbreak.
China reported five new SARS fatalities and 85 new cases Saturday, raising the mainland's death toll to 235. Worldwide, SARS has killed at least 526 people and infected 7,200 others in more than 25 countries.
"Right now, the situation is that we have a whole load of people (in Beijing) and we don't know where they got the disease," WHO spokeswoman Mangai Balasegaram told The Associated Press. "The problem with the data is that there are holes in it."
It is not exactly clear why information is so lacking about Beijing's SARS patients, Balasegaram said, but suggested that some hospitals and health workers had not been trained to question patients correctly.
"That means you don't understand what's going on," she added. "The epidemic might be flying off in one direction, and you might not know about it."
Balasegaram said health officials need to find out "where the people were living, where they went and who they contacted," but added that Beijing was improving its data.
China has been criticized for dragging its feet on releasing information on SARS after the often-deadly disease struck the country in November.
During the early stages of the epidemic, Taiwan was able to quickly trace and isolate the infection sources, many of whom were people who had recently visited China and Hong Kong. But recently, SARS has begun spreading rapidly within communities.
Taiwan reported 23 cases Saturday, its largest one-day jump since the outbreak began there two months ago. Authorities sealed off a housing complex where one resident died of the virus, while one of the largest department stores in Taipei was closed for a major disinfection following the infection of a cashier.
The State Department said Americans residing in Taiwan may wish to consider leaving.
On its Web site, WHO lumped Taiwan together with Chinese cities and regions reporting a rapid transmission of severe acute respiratory syndrome. They included Hong Kong, Beijing, the southern city of Guangdong and the northern province of Shanxi.
WHO said China's danger of SARS could be shifting to the poorer countryside, where a shortage of hospitals and doctors could make an epidemic disastrous. A four-member WHO team was looking into an outbreak in the northern province of Hebei, which borders Beijing.
In the Chinese capital, city officials lifted quarantines on six hospitals, two residential communities and four construction sites where SARS cases were discovered. Authorities also said 80,000 students would be allowed to gather in Beijing next month for college entrance exams.
In a further show of optimism, China's official media reported Saturday that the outbreak won't delay the country's first manned space launch. A front page story in the Communist Party newspaper People's Daily didn't provide a date for the launch of the Shenzhou No. 5, but earlier reports put it in the second half of this year.
In other developments Saturday:
-- In Toronto, health officials said the city has had no new reported cases since late April, and could be declared SARS-free as soon as next week. A nurse suspected of harboring SARS was removed from the list of suspected cases.
-- Hong Kong reported only two deaths -- the lowest daily infection increase so far and a further sign the disease may be on the way out after killing 212 people in the territory.
-- Singapore plans to start electronically tracking every person entering a public hospital in an effort to curb the spread of SARS.
-- The Manila government protested a WHO move to reclassify the Philippines as a country where there is medium-level local transmission of SARS, saying it was hurting its tourism industry.
-- Doctors in Hong Kong said they have adjusted their standard SARS treatment after finding that the flu-like illness has three phases, each requiring different treatments. Changes include delaying the use of steroids.
-- Braving fears of SARS infection, German Chancellor Gerhard Schroeder and a delegation of aides seeking to improve business relations with Southeast Asia departed Saturday for a four-nation tour that will include stops in Malaysia, Singapore, Indonesia and Vietnam.
