To the Editor: The recent article by Chang and colleagues concluded that “the clinical course and outcomes of pandemic (H1N1) 2009 influenza virus are comparable to those of the current circulating seasonal influenza”, and that: “The high number of hospital admissions reflects a high incidence of disease in the community rather than an enhanced virulence of the novel pandemic influenza virus”.1 We are concerned that these assertions underemphasise the true severity of the influenza pandemic, and have led to inappropriate reporting in the media.2
