In May 1997, a 3-year-old boy started showing symptoms of a common cold. When the symptoms - sore throat, fever and cough - continued for six days, he was taken to the Queen Elizabeth Hospital in Hong Kong. There the cough got worse and he started not to fill with air. Despite intensive care, the boy died. Puzzled by his rapid deterioration, doctors sent a sample of the boy's saliva to China's Department of Health. But the standard testing protocol could not fully identify the virus that had caused the disease. The head of virology decided to send some samples to colleagues in other countries.
At the US Centers for Disease Cambodia Telegram Number Data Control and Prevention in Atlanta, the boy's saliva waited a month for the full antibody analysis. The results eventually confirmed that this was a variant of the flu, the virus that has killed more people than any other in history. But this type of flu had never been seen in humans before. It was H5N1, or 'bird flu', discovered two decades ago but known to infect only birds. By then August had arrived. Scientists spread the alarm around the world. The Chinese government promptly killed 1.5 million chickens, despite farmers' protests. Further cases were closely monitored and isolated. By the end of the year, 18 more cases were reported in humans.
Six people died.

In part, control of the disease was possible because it was severe: those who were affected showed it openly because they were very sick. H5N1 has a 60 percent fatality rate—if you get the virus, you're likely to die. However, since 2003, the virus has killed only 455 people. In contrast, much milder flu viruses kill less than 0.1 percent of the people they infect, but are responsible for thousands of deaths each year.
