The reproduction number R for monkeypox as function of immunity in a population to orthopoxvirus species
R: reproduction number; UI: uncertainty interval.
Notes: The R estimates for the monkeypox epidemiology in the Democratic Republic of the Congo in the early 1980s when the smallpox vaccination campaign was coming to an end. The current estimates of R represent countries where accidental exposure to orthopoxvirus species may be considered negligible.
