Impact of heterogeneity on infection probability: Insights from single-hit dose-response models [PDF]

open access: yesarXiv
The process of infection of a host is complex, influenced by factors such as microbial variation within and between hosts as well as differences in dose across hosts. This study uses dose-response and within-host microbial infection models to delve into the impact of these factors on infection probability. It is rigorously demonstrated that within-host

The initial configuration is irrelevant for the possibility of mutual unbounded growth in the two-type Richardson model [PDF]

open access: yesCombinatorics, Probability & Computing 15:3, 345-353 (2006), 2015
The two-type Richardson model describes the growth of two competing infections on $\mathbb{Z}^d$. At time 0 two disjoint finite sets $\xi_1,\xi_2\subset \mathbb{Z}^d$ are infected with type 1 and type 2 infection respectively. An uninfected site then becomes type 1 (2) infected at a rate proportional to the number of type 1 (2) infected nearest ...

Finding an infection source under the SIS model [PDF]

open access: yesarXiv, 2013
We consider the problem of identifying an infection source based only on an observed set of infected nodes in a network, assuming that the infection process follows a Susceptible-Infected-Susceptible (SIS) model. We derive an estimator based on estimating the most likely infection source associated with the most likely infection path.

Nosocomial infections and infection control

open access: yesMedicine, 2017
Abstract Nosocomial infections are a leading cause of avoidable harm in hospital patients and a substantial, unnecessary drain on healthcare resources. They are frequently caused by bacteria that are resistant to multiple antibiotics, and the treatment of nosocomial infections contributes to the selection of resistant bacteria.

The Accuracy of Mean-Field Approximation for Susceptible-Infected-Susceptible Epidemic Spreading [PDF]

open access: yesarXiv, 2016
The epidemic spreading has been studied for years by applying the mean-field approach in both homogeneous case, where each node may get infected by an infected neighbor with the same rate, and heterogeneous case, where the infection rates between different pairs of nodes are different.
