Epidemiological survey to establish thresholds for influenza among children in satellite cities of Tokyo, Japan, 2014-2018.

We described the characteristics of children reported as having influenza across five consecutive influenza seasons and investigated the usefulness of setting influenza thresholds in two satellite cities of Tokyo, Japan.

Methods

Using the World Health Organization method, we established seasonal, high and alert thresholds.

Results
