Ten influenza seasons in France: distribution and timing of influenza A and B circulation, 2003-2013.

ABSTRACT:

Background

Describing the circulation of influenza viruses and the characteristics of seasonal epidemics remains an essential tool to optimize the strategies of influenza prevention and control.
