The 73-year-old came from Nanchang City in central eastern China. She had high blood pressure, heart disease and a muscular disease called myasthenia gravis, but researchers aren't sure to what extent those conditions contributed to her death, and to what extent they can blame her flu. In any case, she first came to a hospital with a fever on November 30, 2013, the third day of her flu. Doctors gave her antibiotic and antiviral treatment, but she eventually developed severe pneumonia, septic shock and multiple organ failure. She died December 6.
