Spatially Extended SHAR Epidemiological Framework of Infectious Disease Transmission

Algorithm 1

Pseudocode for the infection cluster computing algorithm.

If a new infection occurred at in location then update cluster info as follows:

 Create -th column of cluster configuration matrix

 Copy all entries of in

 Update information in as follows:

 If no neighbours of are infected use new cluster label

 Else

  Define vector of indicators of neighboring sites

  Remove zeros and possible repetitions

  If only one label remains then assign the same label to location

  Else

   Compute number of individuals in each neighboring cluster

   Assign to location the label of the largest cluster

  End if

  Update total number of clusters

  Compute number of individuals per cluster

 End if

End if
