Parameter estimates for the best negative binomial generalized linear model explaining total COVID-19 Cases 100 days after the detection of the first case across nations from Mesoamerica and Caribbean. In the model estimates for population size in 2020 for each country were used as offset to account for differences in the size of the population at risk.
