IRSHousingModification

The IRSHousingModification intervention class includes Indoor Residual Spraying (IRS) in the simulation. IRS is another key vector control tool in which insecticide is sprayed on the interior walls of a house so that mosquitoes resting on the walls after consuming a blood meal will die. IRS can also have a repellency effect.

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
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"
    }
}
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"
    }
}
Primary_Decay_Time_Constant float 0 1.00E+0 0 The primary decay time constant (in days) of the decay profile.
{
    "Primary_Decay_Time_Constant": 180
}
Secondary_Decay_Time_Constant float 0 999999 1 The secondary decay time constant of the durability profile. This parameter is used when Durability_Profile is set to CONCENTRATION_VERSUS_TIME.
{
    "Durability_Profile": "CONCENTRATION_VERSUS_TIME",
    "Secondary_Decay_Time_Constant": 730
}
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.
