Table 3. Comparison of dynamics for varying levels of environmental transmission.
The percentage of total infections caused by the environment is determined by the value of ρ. Total deaths are determined at t = 30 days. In all three cases, all turkeys become infected. *The number of infections caused by direct transmission is less than 0.001.
| Percentage | ρ | Time of peak | Infections at peak | Total deaths |
