Report: China had human H5N1 case in late 2003

(CIDRAP News) – A 24-year-old Beijing man died of H5N1 avian influenza in November 2003, nearly two years before China reported any human H5N1 cases to the World Health Organization (WHO), according to Chinese scientists writing in today's New England Journal of Medicine.

The letter has renewed speculation about how many H5N1 cases might have been missed or not reported in China, especially before late 2005, according to news services.
