Abstract:
Background: Emerging infectious diseases are a class of diseases that are
spreading rapidly and are highly contagious. It seriously aPurpose: We aim to propose an eMethods: Using the graph theory method, we first define the network structure of
social groups and construct the risk transmission network of the new epidemic
region. Then, combined with the risk classification method, the classification
of high, medium, and low risk levels of the new epidemic region is discussed
from two cases with common and looped graph nodes, respectively. Finally, the
reasonableness of the classification method is verified by simulation data.
Results: The directed weighted scale-free network can better describe the
transmission law of an epidemic. Moreover, the proposed method of classifying
the risk level of a region by using the correlation function between two regions and
the risk value of the regional nodes can eConclusions: It is necessary to distinguish scientifically between the risk level of
the epidemic area and the neighboring regions so that the constructed social
network model of the epidemic region’s spread risk can better describe the spread
of the epidemic risk in the social network relations.
