Burden of medically attended influenza in Norway 2008-2017.

ABSTRACT:

Background

The burden of influenza in Norway remains uncertain, and data on seasonal variations and differences by age groups are needed.

Objective

To describe number of patients diagnosed with influenza in Norway each season and the number treated in primary or specialist health care by age. Further, to compare the burden of seasonal influenza with the 2009-2010 pandemic outbreak.

Methods

We used Norwegian national health registries and identified all patients diagnosed with influenza from 2008 to 2017. We calculated seasonal rates, compared hospitalized patients with patients in primary care and compared seasonal influenza with the 2009-2010 pandemic outbreak.

Results

Each season, on average 1.7% of the population were diagnosed with influenza in primary care
