InsectKillingFenceHousingModification

The InsectKillingFenceHousingModification intervention class is similar to InsectKillingFence, but is individual-based instead of node-based. Vector control surrounds a designated house with a fence that kills mosquitoes that fly across the path of the fence.

Warning

EMOD simulations models nodes and individuals within nodes; they do not model houses. Therefore, housing modifications are received by individuals, not houses.

Use of this class and other housing modification classes requires caution because they can have unintended effects. For example, individuals in the same household may receive different housing modification interventions. An individual receiving a housing modification intervention who then migrates to another node will continue to receive that intervention. We recommend that you configure your simulation to take these logical inconsistencies into account.

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 format does not permit comments, but you can add “dummy” parameters to add contextual information to your files. Any keys that are not EMOD parameter names will be ignored by the model.

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 }
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": "InsectKillingFenceHousingModification", "Intervention_Name": "Electric fence" } }
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" }
