A 27-year-old woman in Shandong infected with bird flu has died, becoming the second death claimed by the virus this season. Yesterday, the Center for Disease Control and Protection confirmed that Ms. Zhang had contracted the H5N1 strain. Those who came in close contact with her have also been tested, the CDCP said, but have shown no symptoms of avian influenza. Now the tally of reported bird flu cases is up to three. How many does it take before it officially becomes an epidemic? Source: Xinhua (Chinese) more ›
