T r q a r n t e p d h h i o t e s Most virologists would accept the concept that particular viruses often appear to have either acute or persistent patterns of host infection. The polyomaviruses of mammals, for example, uniformly establish persistent infections of a specific host. In contrast, it has recently become clear that avian polyomaviruses infect a broad array of bird species in an acut...

We report here the complete genome sequence of the porcine epidemic diarrhea virus strain CH/ZMDZY/11 isolated from central China. Our data, together with sequence data of porcine epidemic diarrhea virus (PEDV) isolates from other parts in China, will help to understand better the epidemiology and genetic diversity of PEDV field isolates in China.

This study describes a spring 2013 outbreak of porcine epidemic diarrhea virus (PEDv), using data from 222 swine sites in 14 counties area in 4 contiguous states in the United States. During the outbreak, the premises-level incidence of PEDv was 40.5 percent (90/222 sites). One of the three companies from which data were collected had a lower incidence (19.5 percent) than the other two companie...

PURPOSE To report a case of epidemic keratoconjunctivitis complicated by Alcaligenes xylosoxidans. METHODS A 37-year-old man suffered epidemic keratoconjunctivitis in both eyes. Eleven days later, he developed a corneal ulcer in his left eye. Bacterial staining, culture, and antibiotics sensitivity test were performed from a corneal scrape. RESULTS The cultures revealed a growth of Alcalige...

Objectives: In addition to physical damage, the Covid-19 epidemic can cause psychological problems and anxiety in public. Because the elderly is one of the most vulnerable groups in society, the present study aimed to assess the level of anxiety and obsession caused by the Covid-19 epidemic in the elderly and the relationship of those with the ability to perform activities of daily living (ADL)...

Epidemic percolation networks (EPNs) are directed random networks that can be used to analyze stochastic "Susceptible-Infectious-Removed" (SIR) and "Susceptible-Exposed-Infectious-Removed" (SEIR) epidemic models, unifying and generalizing previous uses of networks and branching processes to analyze mass-action and network-based S(E)IR models. This paper explains the fundamental concepts underly...

In this section is presented the stochastic SIS epidemic model for a closed environment. The order of exposition is the following: firstly is presented the deterministic SI epidemic model, secondly is presented the stochastic SI epidemic model, thirdly is presented the deterministic SIS epidemic model and finally is presented the stochastic SIS epidemic model. All these epidemic models are form...
