HIV/AIDS Disease: Transmission Transition

Transmission of Cholera Disease with Laplacian and Triangular Parameters

A mathematical model has been introduced for the transmission dynamics of cholera disease by GQ Sun et al. recently. In this study, we add Laplacian and Triangular random effects to this model and analyze the variation of results for both cases. The expectations  and coefficients of variation are compared for the random models and the results are used to comment on the differences and similarit...

Echinococcosis: disease, detection and transmission.

Echinococcosis is one of the world's most geographically widespread parasitic zoonoses, with transmission occurring in tropical, temperate and arctic biomes. Most human infections are due to Echinococcus granulosus transmitted between domestic dogs and livestock, but this cosmopolitan species also cycles between wild carnivores (principally canids) and wild ungulates. The other species with sig...

Oral transmission of Chagas disease.

Chagas disease is now an active disease in the urban centers of countries of nonendemicity and endemicity because of congenital and blood and/or organ transplantation transmissions and the reactivation of the chronic disease in smaller scale than vectorial transmission, reported as controlled in countries of endemicity. Oral transmission of Chagas disease has emerged in unpredictable situations...

Prudent behaviour accelerates disease transmission

Infectious diseases often spread faster near their peak than would be predicted given early data on transmission . Despite the commonality of this phenomena, there are no known general mechanisms able to cause an exponentially spreading disease to begin spreading faster. Indeed most features of real world social networks, e.g. clustering1,2 and community structure3, and of human behaviour, e.g....

Transition and Sickle Cell Disease

Sickle cell disease (SCD), the most common genetic disease screened for in the newborn period, occurs in ∼1 in 2400 newborns in the general population and 1 in 400 individuals of African descent in the United States. Despite the relative high prevalence and low pediatric mortality rate of SCD when compared with other genetic diseases or chronic diseases in pediatrics, few evidence-based guideli...
