We consider three regions with different public health conditions. In the absence of migration among these regions, the first two have good health conditions and the disease free state is stable; for the third region, on the other hand, the only stable state is the endemic one. When migration is included in the model, we assume that the second region has a disease risk that makes its inhabitant...

The purpose of this report is to present Canada’s experience so far with the emergence of porcine epidemic diarrhea (PED) using a pro-active risk management approach. This approach is reflected in the actions the Canadian Food Inspection Agency took in collaboration with other stakeholders starting from the period the disease was first confirmed in United States to the time after it was confirm...

HAdV-56 is a new recombinant type isolated from epidemic keratoconjunctivitis (EKC) patients and has been sporadically isolated in Japan several times. Here, an outbreak of EKC in the city of Dalian, China involving a large number of workers in two factories was reported; this was the first outbreak of EKC associated with HAdV-56 worldwide.

Since October 2010, an outbreak of porcine epidemic diarrhea (PED) has been observed in some provinces of China. Here we report the complete genome sequence of porcine epidemic diarrhea virus (PEDV) strain LC, which was recently isolated from sucking piglets that suffered from severe watery diarrhea in Guangdong. It will help in understanding the epidemiological and molecular characteristics of...

The mechanisms behind the sub-exponential growth dynamics of the West Africa Ebola virus disease epidemic could be related to improved control of the epidemic and the result of reduced disease transmission in spatially constrained contact structures. An individual-based, stochastic network model is used to model immediate and delayed epidemic control in the context of social contact networks an...

background and purpose: hepatitis b is a major health problem around the globe the prevalence of which varies depending on the region and study. in this study, we aimed to determine the epidemiology and prevalence rates of hepatitis b in fasa, iran. methods: this descriptive, cross-sectional study was performed using medical records of all the hepatitis b patients referring to fasa health cente...

With networks becoming pervasive, research attention on dynamics of epidemic models in networked populations has increased. While a number of well understood epidemic spreading models have been developed, little to no attention has been paid to epidemic control strategies; beyond heuristics usually based on network centrality measures. Since epidemic control resources are typically limited, the...

Many immunization strategies have been proposed to control the epidemic spreading which mainly focus on how to immunize the nodes. A novel and efficient strategy to control the traffic driven epidemic spreading in weighted networks is proposed in this paper. By immunizing the edges according to different weights, our control strategies cannot only reduce the epidemic spreading velocity and enha...
