Links between influenza epidemics, weather characteristics and all-cause mortality in the Czech Republic, 1982-2020.

ABSTRACT:

Background

In temperate climates, influenza follows a seasonal pattern with peak incidence in winter and contributes significantly to excess winter mortality. The relationships among weather variability, influenza, and human health are complex, and the underlying mechanisms remain uncertain. This study investigated how influenza epidemics and all-cause mortality in the nationwide population of the Czech Republic are linked to weather characteristics.

Methods

A quasi-Poisson regression model was used to quantify excess mortality during 25 influenza epidemics over 1982-2020. Mean seasonal deviations of meteorological variables were calculated for periods from six weeks before to four weeks after the peak of influenza epidemics, categorised by their impact on excess mortality (
