Figure 4 Cholera outbreak sources and error in detecting outbreak sources for random reporting node placement.
However, only one network is enough for detecting outbreak sources.
The design of optimal surveillance networks allows stakeholders to detect outbreak sources and paths correctly.
The possible outbreak sources are determined by perturbing the reported outbreaks considering different surveillance networks.
Certainly, the definition of outbreak sources is always dependent on the spatial and temporal scale of the system considered and care has to be placed when planning control strategies based on supposed outbreak sources.
Model-based detection of onset/outbreak sources with uncertainty assigned to the reported outbreaks for all feasible surveillance networks from (1); the determination of outbreak sources is performed by minimizing the uncertainty in the effective distance estimations; and, 3.
The average shortest path tree is calculated among all effective distances that are associated to potential candidate outbreak sources.
Equivalent considerations are related to the scale of analysis: outbreak sources are related to the scale of the system considered.
