An age-of-infection model with both symptomatic and asymptomatic infections [PDF]
arXiv, 2021 We formulate a general age-of-infection epidemic model with two pathways: the symptomatic infections and the asymptomatic infections. We then calculate the basic reproduction number $\mathcal{R}_0$ and establish the final size relation. It is shown that the ratio of accumulated counts of symptomatic patients and asymptomatic patients is determined by ...

Retrovirology, 2018 Background Simian immunodeficiency viruses (SIVs) of chimpanzees and gorillas from Central Africa crossed the species barrier at least four times giving rise to human immunodeficiency virus type 1 (HIV-1) groups M, N, O and P.

On the Universality of Jordan Centers for Estimating Infection Sources in Tree Networks [PDF]
, 2014 Finding the infection sources in a network when we only know the network topology and infected nodes, but not the rates of infection, is a challenging combinatorial problem, and it is even more difficult in practice where the underlying infection spreading model is usually unknown a priori. In this paper, we are interested in finding a source estimator

Evidence for Viral Induction of Biliary Atresia: A Review
Journal of Clinical and Translational Hepatology, 2018 Biliary atresia (BA) is a childhood disease which manifests with abnormal narrowing, blockage or complete absence of bile ducts within the liver. Many possible etiologies have been reported for the development of BA, including congenital, perinatal and ...

Spatially dense stochastic epidemic models with infection-age dependent infectivity [PDF]
arXiv, 2023 We study an individual-based stochastic spatial epidemic model where the number of locations and the number of individuals at each location both grow to infinity. Each individual is associated with a random infection-age dependent infectivity function. Individuals are infected through interactions across the locations with heterogeneous effects.

International Journal of Frontiers in Biology and Pharmacy ResearchFoodborne illnesses constitute a serious global one health issue. The transmission of foodborne viruses can occur due to inadequate hygiene of food, lack of basic sanitation, poor personal hygiene and consumption of raw or undercooked food.

A re-entrant phase transition in the survival of secondary infections on networks [PDF]
, 2018 We study the dynamics of secondary infections on networks, in which only the individuals currently carrying a certain primary infection are susceptible to the secondary infection. In the limit of large sparse networks, the model is mapped to a branching process spreading in a random time-sensitive environment, determined by the dynamics of the ...

Identifying Infection Sources and Regions in Large Networks [PDF]
, 2012 Identifying the infection sources in a network, including the index cases that introduce a contagious disease into a population network, the servers that inject a computer virus into a computer network, or the individuals who started a rumor in a social network, plays a critical role in limiting the damage caused by the infection through timely ...
