InputEIR

The InputEIR intervention class enables the Entomological Inoculation Rate (EIR) to be configured for each month of the year in a particular node. The EIR is the number of infectious mosquito bites received in a night. This number can be calculated by taking the number of mosquito bites received per night and multiplying them by the proportion of those bites that are positive for sporozoites.

This intervention class can be used instead of including vectors in the model, as it will distribute infections to people (it does not model vector biting). However, if vectors are included when this class is implemented, it will add the EIR specified for that month in addition to the EIR provided by the vectors. Note that the Daily EIR channel in the InsetChart will not be impacted by this intervention. When distributing InputEIR to a node that already has an existing InputEIR intervention, the existing intervention of the same name will be purged and replaced by the new one.

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.

Description

Example

Age_Dependence

enum

NA

NA

OFF

Determines how InputEIR depends on the age of the target. Possible values are:

OFF

Age has no effect.

LINEAR

The biting risk for newborns is 20% of the adult exposure and rises linearly to 100% at age 20.

SURFACE_AREA_DEPENDENT

The biting risk rises linearly from 7% to 23% over the first two years of life and then rises with a shallower linear slope to the adult value of 100% at age 20.

  "Age_Dependence": "SURFACE_AREA_DEPENDENT"

Daily_EIR

array of floats

0

1000

[]

An array of 365 values where each value is the mean number of infectious bites experienced by an individual for that day of the year. Used when EIR_Type is set to ‘DAILY’.

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.

NA

An array of exactly 12 elements that contain an entomological inoculation rate (EIR) for each month. Each value should be between 0 and 1000, there is no default. Note that the ‘current month’ is based on the time since the intervention was distributed, and there will be a 12-month repeating pattern from the day it’s distributed. Used when EIR_Type is set to ‘MONTHLY’.
