Full textThis work comprises two parts. It is a study of the dynamics of epidemiological models. The first part deals with malaria intra-host models with and without immunity. For models with immunity we give some results of the global stability by using techniques of dynamical systems (Lyapounov, LaSalle,. . . ). For models with immunity, we improve the De Leenheer –Smith conditions for R0 on the stability of the endemic equilibrium. The second part deals with stastical transmission models and models of the dynamics of the hemorragic fever. For wich we have data on the episodes statistique occured at Mbomo (Congo) and Kikwit (RDC). For the statistical transmission models we compute R0 for data with incomplete contacts (Mbomo) and data with complete contacts b(Kikwit). Lastly, a study on the global stability is done for the dynamic models

Full textCrimean-Congo hemorrhagic fever virus (CCHFV) belongs to Nairovirus genus and to Bunyaviridae family. It is responsible for a severe hemorrhagic disease in humans, associated with non-specific symptoms and high lethality. Transmission is made by tick’s bite or by direct contact with contaminated body fluids. Since no vaccines or treatments are available, there is a need to accumulate knowledge on all aspects of CCHFV-host cell interaction as well as on response mechanisms that are taking place during infection.We first investigated pharmacological ways to interfere with CCHFV replication. Chloroquine and chlorpromazine (known modulators of some viral infections) were efficiently inhibiting viral replication and induce a protection in mice against CCHFV infection, particularly in the presence of ribavirin. Since several viruses are targeted by, or take advantage of, the autophagy response of infected cells, we explored whether CCHFV infection was associated with modulation of autophagy and whether virus replication was impacted by the autophagic activity of infected cells. By using hepatocytes and epithelial cells, we found that CCHFV induced a massive mobilization of the major marker of autophagic vesicles LC3. This mobilization reflected an induced autophagy flux and was of a novel type since known pathways of LC3 recruitment were not involved. The replication of CCHFV was indeed not directly modulated by this atypical form of autophagy but indirect effects remain to be studied. Most of these observations were found to be valid for the related, Dugbe virus (DUGV) with however, a distinct kinetic.Finally, we analyzed whether DUGV was sensitive to the IFITMs, restriction factors that can interfere with membrane fusion processes. Studies revealed that DUGV replication could be inhibited by some IFITMs. Additional studies on virus host-cell interactions and their associated molecular mechanisms should help to better understand the physiopathology induced by CCHFV and to devise therapeutic strategies

Full textProblématique : Les fièvres hémorragiques virales (FHV) sont caractérisées de maladies à mortalité rapide parce que causant la mort dans 50% à 90% des cas cliniquement diagnostiqués (Hewlett et Hewlett, 2005). Le virus Ébola a sévi en 2014 en Afrique faisant plus de 28.607 cas et 11.289 décès. Le virus de Lassa infecte chaque année 100 000 à 300 000 personnes en Afrique de l’Ouest et en tue plus de 5000. La République du Bénin a connu entre 2014 et 2018 quatre épidémies confirmées de FHV Lassa et s’est inscrit sur la liste des pays endémiques à la maladie Lassa. Au total 43 décès, dont 5 agents de santé (un médecin et 4 prestataires de soins) sur 93 personnes infectées ont été enregistrés. Chaque flambée épidémique déclenche une crise de panique dans la population et au sein des agents de santé. But : Cette étude qualitative vise à explorer la pratique infirmière en contexte d’épidémie de FHV Lassa au Bénin afin de mieux comprendre les raisons qui expliquent les fortes létalités enregistrées dans la population et dans le rang des agents de santé. Cadre de référence : Le cadre de référence de l’étude intègre trois éléments : la théorie des soins centrés sur la personne de McCormack et McCance (2015), le cadre de soins fondamentaux de Kitson, Robertson‐Malt et Conroy (2013) et les guides des mesures de prévention et de contrôle des FHV de l’Organisation Mondiale de la Santé (OMS, 2014b) et du Centre de Prevention et de Contrôle et des infections (CDC, 2014). Méthode : Dans le cadre de cette recherche, un devis qualitatif de type d’étude de cas multiple est utilisé avec une approche exploratoire, descriptive et explicative. Trois techniques sont utilisées pour la collecte des données, il s’agit de l’entrevue (type narratif), de l’exploration documentaire et de l’observation. Au total cinq groupes de participants sont recrutés : les survivants patients (n= 4), les survivants patients soignants (n= 2), les prestataires de soins infirmiers et obstétricaux (n= 6), les témoins n’ayant pas administré de soins (n=13), les agents formés pour la prévention et la prise en charge des cas de FHV (n= 6) et les autorités et partenaires impliqués dans la gestion des épidémies (n=7). Résultats : Les cinq thèmes issus du cadre de référence ayant servi de thématiques pour la collecte des données ont servi de base pour l’analyse grâce à la méthode d’analyse de Ritchie, Lewis, Nicholls et Ormston (2013). Ces thématiques sont les suivantes : prérequis, environnement de soin, prestation de soin, la satisfaction au soin et les mesures de prévention et de contrôle des FHV. Les résultats ont mis en relief les facteurs qui expliquent les forts taux de létalité enregistrés durant les épidémies, les contraintes auxquelles les infirmières béninoises sont confrontées pendant l’offre des soins en contexte d’épidémie de FHV Lassa et le rôle autonome qu’elles jouent dans cet environnement de soin à haut risque. Discussion : Cette étude a permis d’explorer les soins infirmiers en contexte d’épidémie mortelle et les conditions d’exercice des infirmières dans les formations sanitaires étudiées. Les résultats empiriques ont fourni des informations pertinentes pouvant servir de guides pour la préparation et l’amélioration de la prise en charge infirmière des cas de FHV Lassa. À cet effet, un modèle de prise en charge centré sur le patient atteint de fièvre Lassa a été proposé pour servir d’outil de travail aux infirmières béninoises et d’Afrique.
Problematic: VHF are characterized as quick lethal fatal diseases because they cause death in 50% to 90% of clinically diagnosed cases (Hewlett & Hewlett, 2005). The Ebola virus struck Africa in 2014, causing more than 28,607 cases and 11,289 deaths. The Lassa virus infects 100,000 to 300,000 people in West Africa every year and kills more than 5,000 one. Between 2014 and 2018, the Republic of Benin experienced four confirmed outbreak cases of Lassa VHF and was recorded on the list of endemic countries to Lassa disease. A total of 43 deaths, including 5 health workers (one doctor and 4 health care providers) out of 93 infected persons were recorded. Each outbreak case triggers a panic attack in the population and among health workers. Purpose: This qualitative study aims to explore nursing practice in the context of the Lassa VHF epidemic in Benin in order to understand more the reasons explaining the high mortality rate among the population and among health workers. Framework: The study framework incorporates three elements: McCormack and McCance's theory of person-centred care (2015), Kitson, Robertson-Malt and Conroy's basic care framework (2013) and World Health Organization's (OMS, 2014b) and Centers for Disease Control and Prevention's guides (CDC, 2014) to VHF prevention and control measures. Method: In this research, a qualitative estimate type of multiple case study is used with an exploratory, descriptive and explanatory approach. Three techniques are used for data collection: interviewing (narrative type), document exploration and observation. A total of five groups of participants were recruited: patient survivors (n=4), caregiver survivors (n=2), nursing and obstetrical care providers (n=6), non-caregiver controls (n=13), trained agents for the prevention and management of VHF cases (n=6) and authorities and partners involved in epidemic management (n=7). Results: The five topics from the reference terms that served as themes for data collection served as the basis for the analysis using Ritchie, Lewis, Nicholls and Ormston's (2013) analysis method. These themes are: prerequisites, care environment, care provision, case satisfaction and measures to prevent and control VHF. The results highlighted the factors that explain the high case-fatality rates during epidemics, the constraints faced by Beninese nurses during the provision of care in the context of a Lassa HSF epidemic and the autonomous role they play in this high-risk care environment. Discussion: This study enabled to explore nursing care in the context of a fatal epidemic and the conditions of practice of nurses in the health facilities studied. The empirical results provided relevant informations that can be used as guideline for the preparation and improvement of nursing management of Lassa VHF cases. To this end, a model of management focused on the Lassa fever patient has been proposed as a working tool for nurses in Benin and Africa.

Full textThe virus Ebola, a negative non segmented RNA virus, is responsible for an hemorrhagic fever disease. Together with the Marburg virus, they compose the Filoviridae family (order Mononegavirales). Ebolavirus is geographically divided into 4 species: Zaire in Central Africa, Sudan in East Africa, Ivory Coast in West Africa, and Reston in Asia. Zaire ebolavirus, first appeared in 1976 in the Democratic Republic of Congo, has the highest mortality rate in humans (up to 88%) and has caused several outbreaks since its re-emergence in 1995. Outbreaks from 2001 to 2005 are characterized by multiple independent epidemic chains and large concomitant outbreaks in chimpanzee and gorillas. The viral glycoprotein (GP) gene was amplified and sequenced from samples obtained during the two last human outbreaks in 2003 and 2005 and samples from great apes carcasses found in the forest of the Gabon-Congo area since 2001. A second viral gene coding the nucleoprotein (NP) was amplified and sequenced from animal samples and human outbreaks since 2001. Phylogenetic analysis based on the GP gene showed the separation of Zaire ebolavirus strains into two genetic lineages. This separation is supported by molecular signatures specific to sequences of each lineage, and by genetic distances between sequences. Analysis based on the NP genes give the same results. However, the topology of human strains recovered between 2001 and 2003 is different in both trees. Results show the existence of two phylogenetic lineages and suggest a recombination event between strains of these lineages.The estimation of the age of the most recent common ancestor tracks back the separation of the lineages before the first appearance of Ebolavirus, up to 1975 (1971 estimated on the NP gene). With this method, the recombination event is dated to 1998-1999

Full textCrimean-Congo hemorrhagic fever virus (CCHFV) is a widely distributed tick-borne member of the Nairovirus genus (Bunyaviridae) inducing an average mortality rate of 30% in humans. CCHFV induces a severe hemorrhagic disease in infected patients that includes, among other bleeding symptoms, acute inflammation and liver lesions. The mononuclear phagocytes, the hepatocytes and the endothelial cells were described to be the main target cells in both human clinical studies and animal model in vivo studies.We analysed the in vitro cellular response of host antigen presenting cells (APC) and hepatocytes. Then, to better elucidate the pathogenesis of CCHFV, we compared the response of these cells after infection with Dugbe virus (DUGV), a mild pathogenic virus genetically close to CCHFV. In order to improve DUGV detection in vitro and in field studies, we also developed a molecular real-time quantitative tool to detect and quantify DUGV.We found that CCHFV induced an inflammatory response in both APCs tested; however DUGV induced a higher cytokine/chemokine response in these target cells than CCHFV. Our results suggest that CCHFV was able to selectively inhibit the activation of some inflammatory mediators in the in vitro infection and that CCHFV/DUGV cellular response differences could be relevant in pathogenesis. On the other hand, when we in vitro infected hepatocytes with CCHFV, we observed that it was able to induce ER-stress, activate IL-8 secretion and modulate both mitochondrial and death receptor pathways of apoptosis. When we compared this cellular response with that induced by DUGV, we found that the most striking difference was the absence of apoptosis. These differences could, in part, explain the role of the liver in the pathogenesis induced by CCHFV

Full textThe Ebola hemorrhagic viral fever is a disease which constitutes a threat for the populations of Central Africa, in particular in rural forester areas. In the Gabon and Republic of Congo (7 epidemics between 1994 and 2005) it became a problem of public health? This zoonos appears at the man's during a direct contact with a contaminated animal, a carcass or a vector of the Ebola virus. The emergence is directly connected, in these enclosed villages, to the ancestral practices of places (hunting, picking, etc. ). The contamination takes place during a direct contact with the physical fluids of a patient. It's made first of all within the families of the victims, during the care lavished on the patients and during those given to the deaths during ceremonies funeral. Firstly, with pathocenosis' concept help, we try in this study to understand in which terms the viral emergence lights us on existing links between people and virus. The amplified rôle of hospital's care confirms the inmportance of the risk in this structure and th panic perception of the world opinion. The North carries a particular interest there. There is no epidemic of Ebola which is accompanied with the procession of international institution. This procession « joins » to the national health system of which takes it territorial is low locally. Several types of care's offers exist with the biomedical model of health represented by « house of health » and health centers. During an epidemic of Ebola, because of his high mortality rate (ut to 80%) and of its contagiousness, the logic of the patient seems more connected to a therapeutic wandering, conditioned by the search for the care and for the causality of the misfortune. In the absence of vaccine, the treatment against Eobla remains symptomatic. The multiplicity of the present actors during the crisis aggravates the anomie created by the disease and highlights a balance of powers, violence, wich is sometimes only the expression of the contesting of the most deprived
