Value

• The ModelSURVfunction returns a model of class epiworld_model.

Arguments

name

String. Name of the virus.

prevalence

Initial number of individuals with the virus.

efficacy_vax

Double. Efficacy of the vaccine. (1 - P(acquire the disease)).

latent_period

Double. Shape parameter of a 'Gamma(latent_period, 1)' distribution. This coincides with the expected number of latent days.

infect_period

Double. Shape parameter of a 'Gamma(infected_period, 1)' distribution. This coincides with the expected number of infectious days.

prob_symptoms

Double. Probability of generating symptoms.

prop_vaccinated

Double. Probability of vaccination. Coincides with the initial prevalence of vaccinated individuals.

prop_vax_redux_transm

Double. Factor by which the vaccine reduces transmissibility.

prop_vax_redux_infect

Double. Factor by which the vaccine reduces the chances of becoming infected.

surveillance_prob

Double. Probability of testing an agent.

transmission_rate

Double. Raw transmission probability.

prob_death

Double. Raw probability of death for symptomatic individuals.

prob_noreinfect

Double. Probability of no re-infection.
