Model diagram. Model diagram. Susceptibles are infected at rates β _C  and β _L  from intact and liquefied cadavers respectively. Exposed hosts die from infection at rate ν and from natural causes or predation at rate μ. Intact cadavers are liquefied at rate λ and contribute to the reservoir at rate θ. Both intact and liquefied cadavers are removed by predators and other causes at the same rate δ. Liquefied cadavers contribute to the reservoir at rate θ, and virus in the reservoir degrades at rate ε. The parameters are summarised in Table 1.
