All the epidemic models encountered so far have assumed aclosedpopulation, i.e. births, deaths, immigration and emigration of individuals are not considered. However, when modelling the spread of a disease with a very long infectious period or a disease in a very large population, dynamic changes in the population itself cannot be ignored. Indeed, in a

Keshan disease-an endemic cardiomyopathy in China
Virchows Archiv A Pathological Anatomy and Histopathology, 1983Keshan disease, an endemic cardiomyopathy in China, was prevalent in rural areas located in a long belt region where the selenium content was low in foods. Intervention studies with well controlled subjects revealed a prophylactic effect of sodium selenite.

Leishmaniases in Maghreb: An endemic neglected disease
Acta Tropica, 2014Maghreb is known to be one of the most endemic areas of leishmaniases where both visceral and cutaneous forms are reported. Cutaneous leishmaniasis (CL) is older and has a higher prevalence than visceral one (VL). It is caused by four taxa (Leishmania (L.) major, L. infantum, L. tropica and L.

Endemic disease in dasyurid marsupials
Pathology, 1972A histological survey was made of a group of 178 dasyurid marsupials which died or were killed. Among the variety of lesions found, infection by a protozoon which morphologically and tinctorially is toxoplasma was particularly common. Despite the presence of an active meningo-encephalitis or myocarditis due to this organism, serological tests for ...

Cryptococcal Disease and Endemic Mycosis [PDF]
, 2011 Cryptococcus and the endemic fungi (Histoplasma, Blastomyces, and Coccidioides) can cause severe, even life-threatening, pulmonary and extrapulmonary disease in immunocompromised patients, including cancer patients and transplant recipients. This chapter describes the epidemiology, clinical manifestations, diagnosis, and treatment of these infections ...

1985
The classical epidemic models derived from the Kermack-McKendrick model consider the prevalence of the disease only. The host population is partitioned into classes of susceptibles S, infectious I, and recovered R. The transition between these classes is described by ordinary differential equations.

Household models for endemic diseases [PDF]
, 2017 The mathematical modelling of disease dynamics is now well-established, which allows us to better understand the processes affecting diseases in communities. Most of this work has focused on epidemic dynamics, in which we see a large out- break of a disease but also its extinction within a short time-frame. Of interest in this thesis will be furthering

Selenium in soil and endemic diseases in China
Science of The Total Environment, 2002Selenium is an essential element for humans, animals and some species of microorganisms. The biological function of selenium shows dual characteristics. The selenium content range between toxic and deficient concentration is very narrow. The present paper discusses the geographical distribution of two forms (total and water-soluble) of selenium in ...

Keshan disease: An endemic cardiomyopathy in China
Human Pathology, 1985Keshan disease is an endemic cardiomyopathy in China. Morphologically, the condition is characterized by multifocal necrosis and replacement fibrosis of the myocardium, resulting in acute or chronic heart failure. Some patients with Keshan disease show the clinical features of congestive (dilated) cardiomyopathy, but the pathologic features of the two ...

Endemic Burkitt's lymphoma: a polymicrobial disease?
Nature Reviews Microbiology, 2005Endemic Burkitt's lymphoma is the most common childhood cancer in equatorial Africa. Two ubiquitous human pathogens are thought to be responsible for the aetiology of this disease: Epstein-Barr virus and Plasmodium falciparum malaria. New data suggest how these two pathogens might interact to result in disease and provide insights into the emerging ...
