ArtificialDietHousingModification

The ArtificialDietHousingModification intervention class is used to include feeding stations for vectors at an individual level in a simulation. For a node-level effect that takes place at the village level, use ArtificialDiet instead. An artificial diet diverts the vector from feeding on the human population, resulting in a two-fold benefit:

  1. The uninfected mosquitoes avoid biting infected humans some of the time, therefore decreasing the amount of human-to-vector transmission.
  2. Infectious vectors are diverted to feed on the artificial diet instead of the humans, therefore decreasing the amount of vector-to-human transmission.

Note

Parameters are case-sensitive. For Boolean parameters, set to 1 for true or 0 for false. JSON does not permit comments, but you can add “dummy” parameters to add contextual information to your files.

The table below describes all possible parameters with which this class can be configured. The JSON example that follows shows one potential configuration.

Parameter Data type Minimum Maximum Default Description Example
Blocking_Config JSON object NA NA NA The configuration of pre-feed mosquito repellency and waning for housing modification. Specify how this effect decays over time using one of the Waning effect classes.
{
    "Blocking_Config": {
        "Box_Duration": 3650,
        "Initial_Effect": 0.0,
        "class": "WaningEffectBox"
    }
}
Cost_To_Consumer float 0 999999 8 The unit cost per housing modification (unamortized).
{
    "Cost_To_Consumer": 10.0
}
Killing_Config JSON object NA NA NA The configuration of killing efficacy and waning for housing modification. Killing is conditional on NOT blocking the mosquito before feeding. Specify how this effect decays over time using one of the Waning effect classes.
{
    "Killing_Config": {
        "Box_Duration": 3650,
        "Initial_Effect": 0.53429,
        "class": "WaningEffectBox"
    }
}
Dont_Allow_Duplicates boolean NA NA 0 If an individual’s container has an intervention, set to true (1) to prevent them from receiving another copy of the intervention. Supported by all intervention classes.
{
    "Dont_Allow_Duplicates": 0
}
Disqualifying_Properties string NA NA NA A list of IndividualProperty key:value pairs that cause an intervention to be aborted (persistent interventions will stop being distributed to individuals with these values). See NodeProperties and IndividualProperties parameters for more information. Generally used to control the flow of health care access. For example, to prevent the same individual from accessing health care via two different routes at the same time.
{
    "Disqualifying_Properties": [
        "InterventionStatus:LostForever"
    ]
}
Intervention_Name string NA NA NA The optional name used to refer to this intervention as a means to differentiate it from others that use the same class.
{
    "Intervention_Name":"Diagnostic_Sample"
}
New_Property_Value string NA NA NA An optional IndividualProperty key:value pair that will be assigned when the intervention is distributed. See NodeProperties and IndividualProperties parameters for more information. Generally used to indicate the broad category of health care cascade to which an intervention belongs to prevent individuals from accessing care through multiple pathways. For example, if an individual must already be taking a particular medication to be prescribed a new one.
