Public health physicians and clinicians keep a wary eye out for influenza epidemics, bearing in mind the greatest pandemic at the end of the first world war, when tens of millions died. The epidemics come every year, but their severity varies. Normally influenza is simply one of many clinically indistinguishable influenza-like illnesses (ILIs) from which people recover uneventfully. Australia’s latest season was worse than most, with a record number of laboratory confirmed cases (170 000), although better availability of molecular tests may account for much of the rise, as visits for ILIs have risen only slightly above the annual average.2 The northern hemisphere is now bracing for its turn.
