However, bird flu is a completely different story. Ten years ago, the H5N1 bird flu swept across 15 countries, includ
12、ing China, with sufferers reporting chest pain, difficulty breathing, fever and severe coughing. More than 600 people were infected, and about 60 percent died. Now another type of bird flu hit Shanghai and three neighboring provinces, and this time the virus is called H7N9. By the afternoon of April
