Effects of city-size heterogeneity on epidemic spreading in a metapopulation: A reaction-diffusion approach

, 2012
We review and introduce a generalized reaction-diffusion approach to epidemic spreading in a metapopulation modeled as a complex network. The metapopulation consists of susceptible and infected individuals that are grouped in subpopulations symbolising ...

Epidemic dynamics in finite size scale-free networks [PDF]

, 2002
Many real networks present a bounded scale-free behavior with a connectivity cut-off due to physical constraints or a finite network size. We study epidemic dynamics in bounded scale-free networks with soft and hard connectivity cut-offs. The finite size

Epidemic model on a network: analysis and applications to COVID-19

, 2020
We analyze an epidemic model on a network consisting of susceptible-infected-recovered equations at the nodes coupled by diffusion using a graph Laplacian.

Phylogenetic analysis and pathogenicity assessment of two strains of avian influenza virus subtype H9N2 isolated from migratory birds: High homology of internal genes with human H10N8 virus

Frontiers in Microbiology, 2016
Two human-infecting avian influenza viruses (AIVs), H7N9 and H10N8, have emerged in China. This development further indicates that as an internal gene donor, the H9N2 subtype of AIVs may have an important role in the generation of new viruses with cross ...

Epidemic processes with immunization

, 2003
We study a model of directed percolation (DP) with immunization, i.e. with different probabilities for the first infection and subsequent infections. The immunization effect leads to an additional non-Markovian term in the corresponding field theoretical
