\(\psi\)

1000

people \(\hbox {day}^{-1}\)

Assumed for model scaling. A constant recruitment rate was chosen for simplicity.

Estimated

\(\beta\)

0.0003

\(\hbox {day}^{-1}\)

Contact rate. Sourced directly from prior literature on a similar model.

5

\(\sigma\)

0.5

\(\hbox {day}^{-1}\)

Assumed to be slower than the initial infection rate (\(\pi\)).

Assumed

\(\gamma\)

0.2

\(\hbox {day}^{-1}\)

Assumed to reflect a moderate-intensity public health campaign.

Assumed

\(\mu\)

0.2

\(\hbox {day}^{-1}\)

Sourced from literature for a theoretical population.

17

\(\delta _1\)

0.01

\(\hbox {day}^{-1}\)

Disease-induced death rate for severe cases. Sourced from literature.

8

\(\delta _2\)

0.001

\(\hbox {day}^{-1}\)

Assumed to be an order of magnitude lower than \(\delta _1\).

Assumed

\(\phi\)

0.1

\(\hbox {day}^{-1}\)

Sourced from literature.

16

\(\Phi\)

0.005

\(\hbox {day}^{-1}\)

Sourced from literature.

9

\(\tau\)

0.836

dimensionless

Fitted within a plausible range (0.7–0.9) to achieve an \({\mathcal {R}}_0> 1\).

Fitted

\(\pi\)

0.2

\(\hbox {day}^{-1}\)

Fitted to ensure a realistic incubation period of \(\sim\)5 days.

Fitted

k

0.1

dimensionless

Assumed to reflect a low baseline education level.

Assumed

\(\epsilon\)

0.3

dimensionless

Reduction in risk for educated class. Sourced from literature.
