Demography and Diffusion in Epidemics: Malaria and Black Death Spread.
Summary of "Demography and Diffusion in Epidemics: Malaria and Black Death Spread."
The classical models of epidemics dynamics by Ross and McKendrick have to be revisited in order to incorporate elements coming from the demography (fecundity, mortality and migration) both of host and vector populations and from the diffusion and mutation of infectious agents. The classical approach is indeed dealing with populations supposed to be constant during the epidemic wave, but the presently observed pandemics show duration of their spread during years imposing to take into account the host and vector population changes as well as the transient or permanent migration and diffusion of hosts (susceptible or infected), as well as vectors and infectious agents. Two examples are presented, one concerning the malaria in Mali and the other the plague at the middle-age.

Medical and Biotech [MESH] Definitions
Epidemics of infectious disease that have spread to many countries, often more than one continent, and usually affecting a large number of people.
Malaria caused by PLASMODIUM VIVAX. This form of malaria is less severe than MALARIA, FALCIPARUM, but there is a higher probability for relapses to occur. Febrile paroxysms often occur every other day.
A complication of MALARIA, FALCIPARUM characterized by the passage of dark red to black urine.
Diffusion Magnetic Resonance Imaging
A diagnostic technique that incorporates the measurement of molecular diffusion (such as water or metabolites) for tissue assessment by MRI. The degree of molecular movement can be measured by changes of apparent diffusion coefficient (ADC) with time, as reflected by tissue microstructure. Diffusion MRI has been used to study BRAIN ISCHEMIA and tumor response to treatment.
Diffusion Tensor Imaging
The use of diffusion ANISOTROPY data from diffusion magnetic resonance imaging results to construct images based on the direction of the faster diffusing molecules.
ABSTRACT: BACKGROUND: Malaria continues to be a global public health challenge, particularly in developing countries. Delivery of prompt and effective diagnosis and treatment of malaria cases, detect...
Why is there greater variability in individual longevity in some populations than in others? We propose a decomposition method designed to address that question by quantifying the effects of populatio...
SUMMARYVery few Pacific islands escaped the 1918-1919 influenza pandemic. Subsequent influenza epidemics in the established colonial outposts of American Samoa and New Caledonia infected many but kill...
Resistance to antimalarial drugs has often threatened malaria elimination efforts and historically has led to the short-term resurgence of malaria incidences and deaths. With concentrated malaria erad...
SUMMARYLarge malaria epidemics in the East African highlands during the mid and late 1990s kindled a stream of research on the role that global warming might have on malaria transmission. Most of the...
The purpose of this study is to see why malaria epidemics occur in highland areas in Kenya. A better understanding of factors contributing to malaria may be necessary for malaria vaccine p...
It has been estimated that black men who have sex with men (MSM) account for one quarter of all new HIV infections in the US annually, yet little prevention work has been directed towards...
Malaria is a disease that affects many people in Africa and in Mali. It is caused by germs that are spread by mosquito bites. This study will look at the safety, effectiveness, and best do...
The purpose of this pilot study is to evaluate the use of (1) 'malaria prevalence', (2) 'malaria incidence' and (3) 'malaria mortality' as a measure of malaria transmission in The Gambia,...
Malaria is a sickness caused by a germ that can get into a person's body when a mosquito bites them. It can cause fever, headache, body aches and weakness. It can even cause death, especia...
