A diarrhea outbreak caused by porcine epidemic diarrhea virus (PEDV) has been observed in China since December 2010. We report here the complete genome sequence of PEDV strain AJ1102 isolated from a suckling piglet with acute diarrhea, which will help toward understanding the molecular and evolutionary characteristics of the epidemic PEDV in China.
In late 2013, outbreaks of porcine epidemic diarrhea virus (PEDV) infection recurred in South Korea. Genetic and phylogenetic analyses showed that isolates from the outbreaks were most closely related to emergent US strains of PEDV. These US strain-like PEDV variants are prevalent in South Korea and responsible for recent outbreaks in the country.
Since late 2007, several outbreaks of porcine epidemic diarrhea virus (PEDV) infection have emerged in Thailand. Phylogenetic analysis places all Thai PEDV isolates during the outbreaks in the same clade as the Chinese strain JS-2004-2. This new genotype PEDV is prevailing and currently causing sporadic outbreaks in Thailand.
Most of the common used models of epidemic spreading allow contaminating many neighbors of a particular node in the network. They are usually analyzed by differential equations on probability vectors. We propose a model of epidemic spreading, which restricts to at most one contamination per time step and analyze it by discrete approach, working on vectors of possible states of the system. Theor...
