How long does the bird flu last?
The average time between exposure and onset of illness was 2-4 days when bird flu first appeared in 1997.
Recent reports indicate the range can be 5-8 days, with 2-4 days still the most common.
The median time from the onset of the first symptoms until death is 9 days.
Those who survive generally begin to recover after approximately 14 days.
