  1. aTotal human rabies deaths; we assume only 10% of these would be reported.
  2. bPEP = post-exposure prophylaxis. The baseline PEP assumption is that 80% (outside Ouest Department) or 85% (Ouest Department) of humans exposed to a suspected rabid dog receive PEP, and that 1/5 suspected exposures are true rabies exposures. In people with true rabies exposures, PEP reduces the probability of death. PEP coverage is assumed to remain fixed throughout 2021–2025 in all scenarios.
  3. cBaseline scenario uses input values as in Table S1. High turnover scenario uses a higher-than-baseline values for dog birth rate and mortality (which define dog turnover rate) and lower R0 (number dogs infected per infectious dog). Low turnover scenario uses lower values defining dog turnover but a higher R0 value (Supplementary Appendix Table S2).
