The World Health Organization said it wants samples from China's suspected SARS case sent to labs overseas for testing because local tests have been inconclusive. Meanwhile, health departments throughout China stepped up anti-SARS measures, days after authorities announced the nation's first suspected case of the disease since July. The capital Beijing, which was hard-hit by severe acute respiratory syndrome earlier this year, ordered airport and railway stations to tighten health checks on travelers and to send anyone with a high fever to a government-designated hospital, the official Xinhua News Agency reported.
