...typically about 80 a day. On this particular day--Tuesday, May 20, 1997--one specimen came from Queen Elizabeth Hospital in Kowloon, at the far side of Victoria Harbor, where a three-year-old boy had been admitted with what turned out to be a fatal respiratory illness. Her lab quickly determined that the infectious agent was some type of Influenza A, one of two broad classes of flu virus that commonly affect humans. To identify the specific strain or subtype, the lab tested the sample, using reagents distributed by the World Health Organization. The test kits triggered no response...
...knew that she had another specimen in her lab, taken from a 13-year-old girl admitted to Prince of Wales Hospital so sick that she had been placed on a respirator. The hospital had identified the underlying virus as Influenza A but wanted Lim to determine the subtype. Lim asked her lab technicians to come in early the next morning, Saturday, Dec. 6, to test specimens from the two patients. Both again reacted to the H5 reagents...
...Queen Elizabeth Hospital sent Lim a specimen from a 54-year-old male who had developed a fever and a cough and soon had to be admitted, apparently suffering from pneumonia. Four days later, Lim's lab succeeded in growing a virus extracted from his specimens. The next day, the patient died. Lim tested the virus with her H5 reagents. Again, a positive...

Taken together, these threads weave a story that begins 80 years ago and winds forward through venues as varied as a high-security lab in Ames, Iowa, the ancient tissue collections of the Armed Forces Institute of Pathology in Washington and a frozen mass grave on Alaska's Seward Peninsula...

Only one teacher pursued conversation with students about extracurricular activities. The variation is surprising...
