# transmissionRiskLevelValues

The level values for transmission risk.

## Declaration

```swift
var transmissionRiskLevelValues: [NSNumber] { get set }
```

## Discussion

Discussion important: This property is available in iOS 12.5, and in iOS 13.5 and later. This property contains eight levels, one for each type of transmission risk: transmissionRiskScores[0] for risk level 0. transmissionRiskScores[1] for risk level 1. transmissionRiskScores[2] for risk level 2. transmissionRiskScores[3] for risk level 3. transmissionRiskScores[4] for risk level 4. transmissionRiskScores[5] for risk level 5. transmissionRiskScores[6] for risk level 6. transmissionRiskScores[7] for risk level 7. Each app defines its own meaning for each of the risk levels (0-7). The values assigned to each risk level should be in the range of 0-8. Consistent Transmission Risk Levels across regions facilitate roaming, therefore it’s recommended that the Transmission Risk Levels describe the type of report. The supported report types are determined by the public health authority for each region. Your app must verify the report type with a public health authority before submitting it. Recommended report types for the different risk levels are: 0 = Unused/Custom 1 = Confirmed test: Low transmission risk level 2 = Confirmed test: Standard transmission risk level 3 = Confirmed test: High transmission risk level 4 = Confirmed clinical diagnosis 5 = Self report 6 = Negative case 7 = Recursive case
