Via Eurosurveillance: Excess mortality among the elderly in European countries, December 2014-February 2015. The abstract:
Since December 2014 and up to February 2015, the weekly number of excess deaths from all-causes among individuals ≥ 65 years of age in 14 European countries have been significantly higher than in the four previous winter seasons. The rise in unspecified excess mortality coincides with increased proportion of influenza detection in the European influenza surveillance schemes with a main predominance of influenza A(H3N2) viruses seen throughout Europe in the current season, though cold snaps and other respiratory infections may also have had an effect.
It would be interesting to see a comparable study of excess mortality in Hong Kong and mainland China; Hong Kong has certainly seen many influenza deaths this winter, and I post the CHP surveillance reports because I assume the rest of China is dealing with similar numbers.
For that matter, I'd love to see such a study about eastern Canada and the northeastern US during the same months. While most of us have been basking in the warmest winter since records began in 1888, eastern Canada and much of New England have been in a very bad cold snap indeed.
