Parameter type | Parameter | Definition |
---|---|---|
Natural history parameters | Days latent | Discrete cdf for number of days between becoming exposed and becoming infectious |
Symptomatic rate | The probability of an infected person becoming symptomatic | |
Days asymptomatic | Discrete cdf for number of days the agent is infectious but asymptomatic | |
Days symptomatic | Discrete cdf for number of days the agent is infectious and symptomatic | |
Immunity loss rate | Rate at which a person loses immunity after recovering from infection | |
Mortality rate | The probability of an infected person dying | |
Contact parameters | Probability of staying home | The baseline probability that an agent stays home if the agent experiences a symptomatic infection. |
Household contact rates | The expected number of potentially infective daily contacts between an infectious agent and a susceptible agent in a household. All contact rates are positive real numbers. | |
Neighborhood contact rates | The expected number of potentially infective daily contacts between an infectious agent and a susceptible agent in a neighborhood | |
School contact rates | The expected number of potentially infective daily contacts between an infectious agent and a susceptible agent in a school | |
Workplace contact rates | The expected number of potentially infective daily contacts between an infectious agent and a susceptible agent in a workplace. | |
Transmission parameters | Transmissibility | The transmissibility of disease relative to an arbitrary baseline set by calibration |
Asymptomatic infectivity | Multiplier for how infective an asymptomatic infected agent is, relative to an symptomatic agent | |
Household transmission probability | A table of probabilities that a potentially infective contact between an infectious agent and a symptomatic agent in the same household actually results in an infection, given the age of the potential infector/infectee pair | |
Neighborhood transmission probability | A table of probabilities that a potentially infective contact between an infectious agent and a symptomatic agent occurring in a neighborhood actually results in an infection, given the age of the potential infector/infectee pair | |
School transmission probability | A table of probabilities that a potentially infective contact between an infectious agent and a symptomatic agent occurring in a school actually results in an infection, given the age of the potential infector/infectee pair | |
Workplace transmission probability | A table of probabilities that a potentially infective contact between an infectious agent and a symptomatic agent occurring in a workplace actually results in an infection, given the age of the potential infector/infectee pair |
