The application is provided with a set of parameters, which are marked in blue within the figure.
Those parameters are regularly downloaded from the CWA Server, which means they can be modified without requiring a new version of the application (see [`exposure-config.yaml`](https://github.com/corona-warn-app/cwa-server/blob/master/services/distribution/src/main/resources/master-config/exposure-config.yaml) for details).

Each of the four risk categories (days since exposure, exposure duration, weighted signal attenuation, and the transmission risk factor) receives an input value from the event which is then mapped to a predefined input value interval. Each of the four risk categories (days since exposure, exposure duration, weighted signal attenuation, and the transmission risk factor) receives an input value from the event which is then mapped to a predefined input value interval.
Each of those input value intervals is then assigned a risk score from 0-8, where 0 represents a very low risk and 8 represents a very high risk. This means that from each of the rows in the figure, one value is selected according to the input value for the corresponding category. As an example: an exposure duration input value of D=15.3 minutes is mapped to the interval 15 < D <= 20, which in the current implementation has a value of 1 assigned to it, i.e. the *Exposure Risk* would be equal to 1 in this example. The product of the four risk scores is used as the **total risk score** of the individual exposure.

Finally, the maximum of the *total risk score* over all the considered events, i.e. the largest risk score, is normalized and then multiplied with the above exposure score. The resulting product of the *exposure score* and the *normalized maximum total risk score* then forms the so called **combined risk score**.

The combined risk score is used to determine which defined risk level should be displayed to the user, e.g. “low risk” or “high risk”. For this decision, [app-defined thresholds](https://github.com/corona-warn-app/cwa-server/blob/master/services/distribution/src/main/resources/master-config/risk-score-classification.yaml) for the individual risk levels apply.

As the values above are multiplied with each other, a single category with a risk score of 0 means that the overall risk score is also 0. As the values above are multiplied with each other, a single category with a risk score of 0 means that the overall risk score is also 0.
Additionally, a central threshold for the combined risk score specifies whether an exposure event should be considered or not. Additionally, a central threshold for the combined risk score specifies whether an exposure event should be considered or not.
Furthermore the Google/Apple framework allows to set a [```minimalRiskScore```](https://developer.apple.com/documentation/exposurenotification/enexposureconfiguration/3583692-minimumriskscore) to exclude exposure incidents with scores lower than the value of this property.
