PATENT PUBLICATION 1242239: A COMPARTMENTAL MODELING APPROACH TO VISCERAL LEISHMANIASIS: TRANSMISSION DYNAMICS, HOST--VECTOR INTERACTIONS, AND CONTROL STRATEGIES

Abstract

🇫🇷 Résumé de Production pour Dépôt de Brevet (Français)Titre : Système de modélisation compartimentale pour la transmission et le contrôle de la leishmaniose viscérale 1242239Domaine techniqueLa présente invention concerne la modélisation épidémiologique, la prévision des maladies infectieuses et les systèmes d’aide à la décision en santé publique, en particulier pour les maladies vectorielles telles que la leishmaniose viscérale.ContexteLa leishmaniose viscérale est une maladie parasitaire grave transmise entre l’être humain, les réservoirs animaux et les phlébotomes (mouches des sables). Les méthodes classiques de surveillance ne permettent pas toujours de prévoir efficacement les épidémies en raison de la complexité du cycle de transmission multi-hôtes et du rôle des porteurs asymptomatiques.Résumé de l’inventionL’invention propose un système mathématique déterministe de modélisation compartimentale permettant de simuler, analyser et prévoir la dynamique de transmission de la leishmaniose viscérale. Le système intègre : Une modélisation multi-populations (humains, animaux, vecteurs) Des compartiments d’infection humaine structurés par stade (susceptible, exposé, asymptomatique, symptomatique, traité, guéri, PKDL) La dynamique d’infection des réservoirs animaux Les compartiments du cycle de vie des vecteurs (susceptibles, exposés, infectieux) Les paramètres d’interaction hôte–vecteur (taux de piqûre, probabilités de transmission)Innovations principales1. Modèle intégré multi-hôtes reliant humains, animaux et vecteurs2. Intégration des cas PKDL et asymptomatiques comme réservoirs de transmission3. Couplage de modèles épidémiologiques par EDO avec des outils de prévision statistique4. Analyse du nombre de reproduction R₀ et bifurcation rétrograde5. Module d’analyse coût-efficacité intégré pour comparer les stratégies d’interventionSimulation des interventionsLe système permet de simuler : Le contrôle des vecteurs adultes Le contrôle des vecteurs immatures Les stratégies de traitement humain Les programmes intégrés de contrôleRésultats fournisLe modèle génère : Des prévisions de prévalence Des projections d’épidémie Des analyses de sensibilité des paramètres Le coût par cas évité pour les stratégies de santé publiqueApplications industrielles et sanitairesCette invention peut être utilisée dans : Les programmes nationaux de surveillance des maladies Les outils de planification sanitaire Les stratégies de lutte antivectorielle La recherche épidémiologique Les systèmes d’alerte précoce assistés par IA

EN Patent 1242239 Filling Production SummaryTitle: Compartmental Modeling System for Visceral Leishmaniasis Transmission and Control1242239Technical FieldThis invention relates to epidemiological modeling, infectious disease forecasting, and public health decision-support systems, specifically for vector-borne diseases such as visceral leishmaniasis (VL).BackgroundVisceral leishmaniasis is a life-threatening parasitic disease transmitted between humans, animal reservoirs, and sandfly vectors. Traditional surveillance methods often fail to predict outbreaks accurately due to the complex multi-host transmission cycle and the role of asymptomatic carriers.Summary of the InventionThe invention provides a deterministic compartmental mathematical modeling system designed to simulate, analyze, and forecast the transmission dynamics of visceral leishmaniasis. The system integrates: Multi-host transmission modeling (humans, animals, sandflies) Stage-structured human infection compartments (susceptible, exposed, asymptomatic, symptomatic, treated, recovered, PKDL) Animal reservoir infection dynamics Vector life-cycle compartments including susceptible, exposed, and infectious sandflies Host–vector interaction parameters, including biting rate and transmission probabilitiesCore Innovations1. Integrated multi-population disease model capturing human, animal, and vector interactions2. Inclusion of PKDL and asymptomatic carriers as transmission reservoirs3. Coupling of epidemiological ODE models with regression-based forecasting tools4. Backward bifurcation and R₀ analytical framework to assess disease persistence even when transmission thresholds are low5. Embedded cost-effectiveness evaluation module for comparing intervention strategiesIntervention Simulation CapabilityThe system enables simulation of: Adult vector control (e.g., insecticide spraying) Immature vector control (larval stage reduction) Human treatment strategies Combined integrated control programsOutputsThe model produces: Disease prevalence forecasts Outbreak trajectory predictions Sensitivity analysis of transmission parameters Cost per case averted for public health strategiesIndustrial & Public Health ApplicationsThis system can be implemented in: National disease surveillance programs Public health planning tools Vector control strategy design Epidemiological research platforms AI-assisted outbreak early warning systems
