When, 20-year-old Phyllis Burn succumbed to flu during the great pandemic (大范围流行病) of 1918, she was just one victim out of an estimated 25 million across the world. But her wealthy family’s decision to bury her in an expensive, lead-lined coffin (棺材) will help a present-day virologist（病毒学家）in his quest to understand what turns an ordinary flu virus into a killer.
Phyllis had just returned to London from service as a Red Cross ambulance driver in France during the First World War. She had survived the horrors and hardships at the front, only to face another kind ofwar—with the virus that was spreading through her body.
It’s known that Phyllis spent her final days in a house a street away from the family home, perhaps because she was afraid of infecting her nearest and dearest. On 30 th October she took her last breath. It was at the height of the flu epidemic, and some victims were being buried in cardboard coffins or simply wrapped in newspaper. But Phyllis’s family could afford the best that money could buy.
John Oxford, a virologist at Queen Mary’s School of Medicine in London, is glad they did. He’s been searching for preserved samples of the 1918 flu virus for several years. The hope is that sequencing the genome（基因组）of the flu that caused the worst pandemic in recorded history will help to arm ourselves against future outbreaks.
After scanning over thousands of burial records in London from autumn 1918, Oxford came upon Phyllis.
