Table 4 Parameter values used in the AB simulation model

From: Estimating disease burden of a potential A(H7N9) pandemic influenza outbreak in the United States

Parameter

Values

β h

0.47/day (for R 0 = 1.8); 0.39/day (for R 0 = 1.5)

\( {\beta}_p^j \)

0.94/day for schools and 0.47/day for workplaces (for R 0 = 1.8); 0.78/day for schools and 0.39/day for workplaces (for R 0 = 1.5)

β c

0.075/day (for R 0 = 1.8); 0.06/day (for R 0 = 1.5);

κ(t − τ k )

lognormal distribution with: δ = − 0.72 and γ = 1.8

\( {\psi}_p^j\left(t-{\tau}_k\right) \)

0.2 (for schools) and 0.5 (for workplaces) only when the elapsed time since the onset of infection is greater than the latent period 0.25 days; the value of \( {\psi}_p^j \) is 0 otherwise

f(d i , k)

\( \frac{1}{{\left[1+\frac{d_i,k}{a}\right]}^b}, \)Z with a = 35 km and b = 6.5

ζ(a i )

ζ(a i ) = 100% if age [20 − 65], 75% if age [15 − 20] and [65 − 70], 50% if age [10 − 15] and [70 − 75], 25% if age [5 − 10] and [75 − 85], 0% if age [0 − 5]

ρ k

1

C k

1 if individual k is a severe infection, 0 otherwise

ω

2

\( {n}_i^{\alpha } \)

obtained from the households generated by the model

α

0.8

\( {m}_i^j \)

obtained from the population and places generated by the model

death rate

symptomatic

50%
