Query: The Basic Reproductive Number of Ebola and the Effects of Public Health
  Measures: The Cases of Congo and Uganda   Despite improved control measures, Ebola remains a serious public health risk
in African regions where recurrent outbreaks have been observed since the
initial epidemic in 1976. Using epidemic modeling and data from two
well-documented Ebola outbreaks (Congo 1995 and Uganda 2000), we estimate the
number of secondary cases generated by an index case in the absence of control
interventions ($R_0$). Our estimate of $R_0$ is 1.83 (SD 0.06) for Congo (1995)
and 1.34 (SD 0.03) for Uganda (2000). We model the course of the outbreaks via
an SEIR (susceptible-exposed-infectious-removed) epidemic model that includes a
smooth transition in the transmission rate after control interventions are put
in place. We perform an uncertainty analysis of the basic reproductive number
$R_0$ to quantify its sensitivity to other disease-related parameters. We also
analyze the sensitivity of the final epidemic size to the time interventions
begin and provide a distribution for the final epidemic size. The control
measures implemented during these two outbreaks (including education and
contact tracing followed by quarantine) reduce the final epidemic size by a
factor of 2 relative the final size with a two-week delay in their
implementation.
