Parasite infestation risk
Forecasts of infestation risk for coming week are indicated by risk maps, consisting of 5 risks levels represented on a scale from 1 (lowest risk) to 5 (highest risk).
The Risk Index (RI) is calculated according to the following formula:
Risk Index (RI) = √(AIxDI)
AI=Activity Index, DI= Density Index
Transmission risk of vector-borne disease
As arthropod parasite activity increases, the greater the risk of infestation is and this will result in an increase in the risk of disease transmission.
