+Covid-19 as well haemorrhagic fevers such as Ebola virus disease:
 
 1.  A deterministic SEIR-V model with susceptible, exposed, infectious,
     recovered, and vaccinated compartments (SEIR-V), allowing for
     heterogeneity in social contacts, the implementation of a
     group-specific non-pharmaceutical intervention that reduces social
     contacts, and a vaccination regime with group-specific start and end

 2.  The deterministic Vacamole model developed at [RIVM, the Dutch
     Public Health Institute](https://www.rivm.nl/) for the Covid-19
     pandemic, with a focus on scenario modelling for hospitalisation and

 3.  A stochastic, discrete-time, compartmental SEIR model suitable for
     modelling haemorrhagic fevers such as Ebola Virus Disease, including
     hospitalisation and hospital and funeral transmissions, adapted from
