ImportPressure

The ImportPressure intervention class extends Outbreak by importing infected individuals into a node at a configurable rate over specified time periods. Each element in the Daily_Import_Pressures array is applied for the corresponding number of days in the Durations array, allowing time-varying importation schedules. The imported cases are created with the specified Antigen, Genome, and Import_Age.

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 Type Min Max Default Description
Antigen integer 0 10 0 The antigenic base strain ID of the outbreak infection.
Daily_Import_Pressures array of floats 0 3.40282e+38 0 The rate of per-day importation for each node that the intervention is distributed to.
Durations array of integers 0 2.14748e+09 1 The durations over which to apply import pressure.
Genome integer -1 1.67772e+07 0 The genetic substrain ID of the outbreak infection. Together with Antigen, they are a unitary object representing a strain of infection, which allows for differentiation among infections. Values for Genome may range from -1 to \(2^{Log2\_Number\_of\_Genomes\_per\_Clade-1}\)
Import_Age float 0 43800 365 The age (in days) of infected import cases.
