Leptospirosis as model of neglected endemic pathogen with multiple transmission routes and reservoirs
Leptospirosis is a zoonosis occurring worldwide, caused by the pathogenic bacterium Leptospira.
Leptospirosis is one of the top ten infectious hazards reported globally and is transmitted to people and animals through exposure to water and soil contaminated by the urine of infected animals, namely rodents. In 2015, 222 leptospirosis cases, including 626 (51%) confirmed cases, were reported by 29 EU/EEA countries and the notification concerned mainly the severe cases in PH (40%). With global climate change, extreme weather events are expected to occur with increasing frequency and greater intensity and may potentially result in an upsurge in disease incidence as well as the magnitude of leptospirosis outbreaks.
Despite efforts in research, the true spread and increase of leptospirosis remain unknown, as the risk distribution, detection and data accessibility pose serious challenges to epidemic intelligence in Europe.
MOOD tools for Leptospirosis
Generic module for event-based surveillance
1a. PadiWeb + ProMED (tbc) connected to visualisation engine (EpiVis)
Generic data access module
In order to get an efficient intersectoral collaboration that can allow identifying sites with an increased risk of leptospirosis in humans and animals, a dashboard could help visualisation of leptospira laboratory data (on cases and serotypes) and their space-time clusters in link with the query, visualisation and download of covariates (vector, host, environment) for this disease.

Updates from 23-24 June 2022:
- Need for better visualization of animal cases and serotypes of Leptospirosis in metropolitan France using the data from the National Reference Laboratory (NRL) at VetsupAgro. There is already a prototype of a visualization platform developed from LIRMM for the NRL and the exchange on the prototype functionalities will continue in the forthcoming period;
- Need to better understand the spatio-temporal evolution of the Leptospirosis human incidence in particular based on climate change in the french overseas territories in the Indian Ocean to support disease surveillance at the commune level. CIRAD will further exchange on data provisioning, data sharing and modeling with local authorities from SPF and ARS from the french oveseas territories in the Indian Ocean.
Process
- Review of literature
- Dashboard on main covariates, environment, climate, host and vectors for leptospirosis from review of literature
- Dashboard for visualisation, exploration and download of Leptospiris covariates, environment, climate, hosts and vectors

Updates from 23-24 June 2022:
- Main end-users are the SPF and ARS at the Réunion and Mayotte island in the french overseas territories in the Indian Ocean
- Need to better understand the risk of introduction and circulation of different viral subtypes in the french overseas territories in the Indian Ocean and the risk of introduction of Dengue in metropolitan France using data from flight movement of passengers ;
- CIRAD will attempt to best support local authorities from SPF and ARS from the french oveseas territories in the Indian Ocean to address the above mentioned needs. Support from MOOD partners with expertise in modeling Dengue and human movements will be highly appreciated in the forthcoming period.
