HumanHostSeekingTrap

The HumanHostSeekingTrap intervention class applies a trap that attracts and kills host-seeking mosquitoes in the simulation. Human-host-seeking traps are individually-distributed interventions that have attraction and killing rates that decay in an analogous fashion to the blocking and killing rates of bednets.

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.

Parameter	Data type	Minimum	Maximum	Default	Description	Example
Attract_Config	JSON object	NA	NA	NA	The configuration of attraction efficacy and waning for human host-seeking trap. Specify how this effect decays over time using one of the Waning effect classes.	{ "Attract_Config": { "Box_Duration": 3650, "Initial_Effect": 0.6, "class": "WaningEffectBox" } }
Cost_To_Consumer	float	0	999999	3.75	The unit cost per trap (unamortized)	{ "Cost_To_Consumer": 4.5 }
Disqualifying_Properties	array of strings	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" ] }
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": "HumanHostSeekingTrap", "Intervention_Name": "Trap to lure and kill mosquitoes" } }
Killing_Config	JSON object	NA	NA	NA	The configuration of killing efficacy and waning for human host-seeking trap. Specify how this effect decays over time using one of the Waning effect classes.	{ "Killing_Config": { "Box_Duration": 3650, "Initial_Effect": 0.9, "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" }
