Texto completoThe main purpose of this thesis is to study a class of mathematical models describing some problems related to the infection by the Plasmodium falciparum parasite which causes malaria and whose vector is the mosquito.The work is divided into three main parts, the first part is related to the analysis of the spread of malaria in an isolated population. The global stability of the disease-free equilibrium is studied according to the different epidemiological parameters when the number of basic reproduction is lower than one. When this number is higher than one, the existence of a unique endemic equilibrium is proved. Inspired by the geometric approach introduced by Li and Muldowney, we provided a sufficient condition for this endemic equilibrium to be globally asymptotically stable.A state estimator was constructed to estimate the size of human populations based on the measurement of the number of newly infected humans per unit time. We also proposed two control strategies to eradicate the disease.Finally, to better understand the dynamics of the spread of the disease and to identify the most influential parameters, we have studied the local sensitivity of the number of basic reproduction with respect to each parameter.The second part is about the study of a model that describes the interaction and the spread of the disease within a human population that is divided into two subpopulations, local and non-local. The first subpopulation follows a linear growth while the non-local population follows a logistic growth among the first. We choose to study the impact of the migration of people from an endemic country to another country declared free of the disease or towards the eradication of the disease.Our analysis yielded conditions of the persistence of the disease, we studied the possibility of controlling the disease in a first step through the control of the carrying capacity, then we developed a method based on a matrix called matrix of vectorial transmission which was used to determine the link between the two subpopulations and the population of mosquitoes, according to the values of this matrix entries in order to ensure the control of the disease spread. In addition, a local and global sensitivity study of the level of local and non-local infection was performed to determine the most influential model input parameters.The last part is devoted to the study of the global dynamics of models with multiple subpopulations that are assumed to be weakly interconnected. Our work highlights a process that allows us to perform a complete analysis of many dynamical systems modeling the spread of a disease that involves different populations. The objective is to be able to determine the global stability of the disease-free equilibrium when the basic reproduction number is less than one as well as the global stability of the different types (interior or frontier) of endemic equilibria as a function of the different local basic reproduction numbers and the nature of the interconnections between the network components

Texto completoIn the first part of this thesis, we have developed a malaria transmission metamodel based on the susceptible-infected-resistant compartmental modeling framework (SIR) and taking into consideration human mobility flows between different villages in the Center of Senegal. Geographically targeted intervention strategies had been shown to be effective in reducing the incidence of malaria both within and outside of intervention areas. However, combined interventions targeting both vector and host, coordinated on a large scale are needed in regions and countries aiming to achieve malaria elimination in the short/medium term.In the second part we have evaluated different methods of estimating human mobility in the absence of real data. These methods included spatio-temporal traceability of mobile phones, mathematical models of gravity and radiation. The transport of the pathogen through the geographical space via the mobility of an infected subject is a major determinant of the spread of an epidemic. We introduced the impedance model that minimized the mean square error on mobility estimates, especially in contexts where population sets are characterized by their heterogeneous sizes.Finally, we have expanded the framework of assumptions underlying the calibration of the gravity models of human mobility. The hypothesis of a zero inflated distribution provided a better fit and a better predictability, compared to the classical approach not assuming an excess of zeros: Poisson, Quasipoisson

Texto completoIn this thesis, we analyse intrahost models of malaria and H. I. V. These models are of relatively recent appearance and describe the dynamics of the various stages of the parasites, like their interaction with the host cells, in particular the red blood cells and the immunity effectors. During this decade, there was a considerable work on the mathematical modeling of plasmodium falciparum infection ; a review has been done by Molineaux and Dietz. Our work forms part of this effort of comprehension of the models of Anderson, May and Gupta. The study of these models aims three principal goals : to explain the observations by biologically convincing assumptions, to predict the impact of the interventions (for example the use of the anti-paludic drugs and impregnated mosquito nets) and to consider the parameters hidden (one of these parameters being size of the sequestered population of red blood cells). We analyze the stages progression and the differential infectivity models ; then we leave the original model of Anderson, May and Gupta to propose and analyze a general model having the double advantage of describing the dynamics of evolution of the red blood cells, as well as the stages of morphological evolution of the parasites inside the parasitized red blood cells ; to finish we analyze a model whose innovation compared to the precedent is the bond between the compartment of susceptibles and that of the infectious one. We establish in all the studied cases here the global asymptotic stability of the disease free equilibrium (DFE) when the basic reproduction ratio R0 1. What means that the disease naturally dies out. We also obtain for each model studied here, a condition for global asymptotic stability of the endemic equilibrium when R0 > 1. In certain cases, the principle of exclusive competition is also used to slice

Texto completoThe objective of this thesis is first the modeling, the mathematical analysis and numerical simulations of the metapopulation models of infectious diseases based on some modern approaches of the mobility patterns of humans. Secondly to examine the influence of the mobility (movement) of people on the spread of some human infectious diseases. Finally to deal with the difficult question of the existence and stability of endemic equilibria of metapopulation models. For certain diseases such as Malaria, Tuberculosis or some Sexually Transmitted Diseases that do not confer any immunity, we give some metapopulation models that extend to multiple patches the well know epidemiological models in one patch. Our models are based on the mobility patterns of humans wich can take different forms leading to numerous approaches of modeling metapopulations : the Euler approach of the movement of particles (here humans) as in Fluid Mechanics, is used in the first part. The Lagrange approach of the movement of particles (here humans) as in Fluid Mechanics, is used in the second part. The last and more recent approach based on Statistical Mechanics, wich takes into account the degree distribution of the network of the metapopulation is used in the third and last part of this work. For each approach, we build a metapopulation model for a chosen disease, and gve its mathematical analysis. The theoretical framework we use to analyze ou models is that of triangular, monotone or anti-monotone non-linear dynamical systems. We also use some Lyapunov-Lasalle techniques. In the fisrt two parts of our work, we prove that the steady solutions (called equilibria) of the given systems are globally asymptotically stable when the basic reproduction number R0 is less than or equal to the unity (for the disease free equilibria), and when R0 is greater than one (for the endemic equilibria). In the last part, we build a model to describe the spreading of tuberculosis hinging on the two most used forces of infection in mathematical modeling of epidemics : the frequency-dependant transmission and the density-dependant transmission. For each type of trasmission model, we give the explicit formula for the basic reproduction number. We prove for the frequency-dependant transmission model, that the disease free equilibrium is globally asymptotically stable when R0 is less than one. And for the density-dependant transmission model, we prove the existence of an endemic equilibrium when R0 is greater than one. Numerical simulations are performed at the end of each part to examine the influence of human's mobility on the basic reproduction number, as well as on the behavior of the solutions and consequently on the spreading patterns of the diseases under study
