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. Minimum, maximum, or default values of “NA” indicate that those values are not applicable for that parameter.

EMOD does not use true defaults; that is, if the dependency relationships indicate that a parameter is required, you must supply a value for it. However, many of the tools used to work with EMOD will use the default values provided below.

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.

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
}

Disqualifying_Properties

array of strings

NA

NA

[]

A list of NodeProperty key:value pairs that cause an intervention to be aborted (persistent interventions will stop being distributed to nodes 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"
    ]
}

Dont_Allow_Duplicates

boolean

0

1

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
}

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_Config": {
        "class": "IRSHousingModification",
        "Intervention_Name": "Indoor DDT spraying"
    }
}

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"
    }
}

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.

    "New_Property_Value": "InterventionStatus:None"
