TAIWAN-CHINA-HEALTH-FLU

Two masked security guards standby at an entrance to Taipei Hoping Hospital on April 6, 2013 where new isolation units have been set up to treat potential new H7N9 avian influenza cases. Taiwan enhanced its level of alert against bird flu and set up a contingency centre on April 3 after reports in mainland China of new infections from a new strain of avian influenza. The new infections alarmed the authorities in Taiwan, which is separated from the Chinese mainland only by a 180-kilometre (111.6 miles) strait and which has seen a dramatic influx of 2.6 million Chinese visitors last year due to the fast warming ties between Taipei and Beijing.
