Recent studies have increasingly turned to graph theory to model more realistic contact structures that characterize disease spread. Because of the computational demands of these methods, many researchers have sought to use measures of network structure to modify analytically tractable differential equation models. Several of these studies have focused on the degree distribution of the contact ...

Cannibalism has been documented as a possible disease transmission route in several species, including humans. However, the dynamics resulting from this type of disease transmission are not well understood. Using a theoretical model, we explore how cannibalism (i.e. killing and consumption of dead conspecifics) and intraspecific necrophagy (i.e. consumption of dead conspecifics) affect host-pat...

the health of the world rural community has become the focus of attention during the past several years. realizing the future of the traditional system of medical practice many countries have initiated specific public health programmes in order to alleviate the plight of this group of people. however, in their effort to establish such programmes the medical community must not be oblivious of th...

Tetanus and other widespread endemic diseases of Brazil's early national period speak to intimate details of common life and give clues to big, vexing questions, such as why Brazil's population expanded dramatically at the turn of the twentieth century. Tetanus was for a long time one of Brazil's deadliest afflictions, especially among infants, but historians know very little about it. Using ar...

This original study describes the intra-urban distribution of cases of leprosy in residents under 15 years old in Salvador, Bahia, Brazil; the study also identifies the environment in which Mycobacterium leprae is being transmitted. The cases were distributed by operational classification, clinical forms, type of contact and the addresses were geo-referenced by neighborhood. Between 2007 and 20...

Cutaneous leishmaniasis(CL) is referred to a group of diseases because of the varied clinical presentation, ranging from small cutaneous nodule to wide spread mucosal destruction. The nose is rarely involved by CL in even in endemic region. In this report we describe a rare rhinophymatous presentation of CL from a non-endemic region which was diagnosed by fine needle sampling and treated with M...
