| T1 |
108-218 |
DRI_Background |
denotes |
Infectious diseases in livestock can be transmitted through fomites: objects able to convey infectious agents. |
| T2 |
219-411 |
DRI_Background |
denotes |
Between-farm spread of infections through fomites is mostly due to indirect contacts generated by on-farm visits of personnel that can carry pathogens on their clothes, equipment, or vehicles. |
| T3 |
412-537 |
DRI_Background |
denotes |
However, data on farm visitors are often difficult to obtain because of the heterogeneity of their nature and privacy issues. |
| T4 |
538-690 |
DRI_Background |
denotes |
Thus, models simulating disease spread between farms usually rely on strong assumptions about the contribution of indirect contacts on infection spread. |
| T5 |
691-890 |
DRI_Approach |
denotes |
By using data on veterinarian on-farm visits in a dairy farm system, we built a simple simulation model to assess the role of indirect contacts on epidemic dynamics compared to cattle movements (i.e. |
| T6 |
909-1121 |
DRI_Outcome |
denotes |
We showed that including in the simulation model only specific subsets of the information available on indirect contacts could lead to outputs widely different from those obtained with the full-information model. |
| T7 |
1122-1313 |
DRI_Approach |
denotes |
Then, we provided a simple preferential attachment algorithm based on the probability to observe consecutive on-farm visits from the same operator that allows overcoming the information gaps. |
| T8 |
1314-1464 |
DRI_Outcome |
denotes |
Our results suggest the importance of detailed data and a deeper understanding of visit dynamics for the prevention and control of livestock diseases. |
