Transmission Decay

• Taken from Statistical Inference in a Stochastic
  Epidemic SEIR Model with Control Intervention
  Ebola as a Case Study, by Phenyo E. Lekone, et.
  al.
• In order to account for the control intervention
  we assume that the transmission parameter is
  constant up to the time point when the control
  measures are introduced and after that decays
  exponentially. This can be formulated as
• where t is the time point at which control
  measures are introduced, is the initial
  transmission rate, and qgt0 is the rate at which
  decays for tgtt.
