*DRC, Democratic Republic of Congo; MCMC: Markov chain Monte Carlo; MLE, maximum-likelihood estimation; SEIR, susceptible-exposed-infectious-removed; SEIHFR, susceptible-exposed-infectious-hospitalized-funeral-removed. Blank cells indicate that no information was provided from the original study. †The incubation period for Ebola virus is believed to be the same as its latent period, i.e., infected persons become infectious only when symptomatic. ‡Combination differential equation model and Markov chain model. §Neither CIs nor SDs were provided in the study.
