mpox_19801984_DRC {modelSSE}

A dataset of mpox outbreaks in DRC

Description

This dataset (i.e., mpox_19801984_DRC) contains 125 observations of one of the following types:

• offspring case number,

• next-generation cluster size, and

• final outbreak size,

generated by given numbers of seed cases, which were collected in mpox (i.e., monkeypox) outbreaks in Democratic Republic of the Congo (DRC, or previous named "Zaire" before 1997) from 1980 to 1984.

Usage

mpox_19801984_DRC

Format

A data frame (data.frame) with 125 rows of records, and 3 columns of variables:

obs.seed

Observations of the number of seed cases that generated the offspring cases in the next transmission generation.

obs.size

Observations of cases numbers generated by given numbers (given in obs.seed) of seed cases, see type variable for the detailed meaning of the value recorded under this variable here.

type

A categorical variable takes one of the 3 values indicating the type of observations for obs.size as follows:

• "offpring" indicated the offspring case number, generated by 1 seed case for each observation.

• "nextgen" indicated the next-generation cluster size (including seed cases), generated by a group of seed cases with size given in obs.seed.

• "outbreak" indicated the final outbreak size (including seed cases), generated by a group of seed cases with size given in obs.seed.

Details

Note one difference between mpox_19801984_DRC and the original dataset (i.e., the dataset presented in reference) was that for simplicity, observations in the original dataset that involved transmission chains of more than 1 generation were aggregated as final outbreak size observations in mpox_19801984_DRC.
