Confirmed 2003 AI death in China first case in current outbreak
The Ministry of Health in China has retrospectively confirmed a human
case of H5N1 bird flu infection dating back to November
The case occurred in a 24-year-old man who developed symptoms on 25 November
2003 and was hospitalised with pneumonia in Beijing. His condition deteriorated
rapidly and he died of severe respiratory disease on 3 December 2003.
Confirmation of this case marks the earliest known instance of human H5N1 avian
influenza infection in mainland China, and is now the first confirmed case
in the present outbreak. Previously, the first confirmed cases were thought to
have occurred in Vietnam in December 2003.
Retrospective confirmation of the case brings the cumulative total in China
to 20. Of these cases, 13 have been fatal.
The case has been added to the World Health Organisation (WHO) cumulative table of confirmed
cases which today shows a total of 235 cases and 137 deaths from bird

poultry exposure was taken. The source of his H5N1 infection remains uncertain,
particularly as no poultry outbreaks of H5N1 avian influenza have been reported
The Ministry of Health has informed WHO of
its intention to strengthen communication mechanisms, and to ensure that more of
the country's research institutes are integrated into the reporting system. WHO
will be providing support and guidance in these activities, as officially
