An epidemiological model for proliferative kidney disease in salmonid populations

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Marino Gatto, Luca Carraro

Background: Proliferative kidney disease (PKD) affects salmonid populations in European and North-American rivers. It is caused by the endoparasitic myxozoan Tetracapsuloides bryosalmonae, which exploits freshwater bryozoans and salmonids as hosts. Inciden ...

The temporal patterns of disease severity and prevalence in schistosomiasis

Andrea Rinaldo, Lorenzo Mari, Marino Gatto

Schistosomiasis is one of the most widespread public health problems in the world. In this work, we introduce an eco-epidemiological model for its transmission and dynamics with the purpose of explaining both intra-and inter-annual fluctuations of disease ...

Spatial patterns of schistosomiasis in Burkina Faso: relevance of human mobility and water resources development

Andrea Rinaldo, Enrico Bertuzzo, Francisco Javier Perez Saez, Natalie Claire Ceperley, Theophile Mande, Lorenzo Mari, Marino Gatto

Detection of Vibrio cholerae O1 and O139 in environmental waters of rural Bangladesh: a flow-cytometry-based field trial

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Righetto, Lorenzo Mari, Marino Gatto

Presence of Vibrio cholerae serogroups O1 and O139 in the waters of the rural area of Matlab, Bangladesh, was investigated with quantitative measurements performed with a portable flow cytometer. The relevance of this work relates to the testing of a field ...

A Theoretical Analysis of the Geography of Schistosomiasis in Burkina Faso Highlights the Roles of Human Mobility and Water Resources Development in Disease Transmission

Yeli Mariam Sou, Andrea Rinaldo, Enrico Bertuzzo, Francisco Javier Perez Saez, Natalie Claire Ceperley, Theophile Mande, Lorenzo Mari, Marino Gatto

We study the geography of schistosomiasis across Burkina Faso by means of a spatially explicit model of water-based disease dynamics. The model quantitatively addresses the geographic stratification of disease burden in a novel framework by explicitly acco ...

The Haiti cholera epidemic: from surveillance to action

Maney Publishing2014

Floquet theory for seasonal environmental forcing of spatially explicit waterborne epidemics

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Marino Gatto

The transmission of waterborne pathogens is a complex process that is heavily linked to the spatial characteristics of the underlying environmental matrix as well as to the temporal variability of the relevant hydroclimatological drivers. In this work, we ...

Metapopulation persistence and species spread in river networks

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Marino Gatto

River networks define ecological corridors characterised by unidirectional streamflow, which may impose downstream drift to aquatic organisms or affect their movement. Animals and plants manage to persist in riverine ecosystems, though, which in fact harbo ...

Cholera in the Lake Kivu region (DRC): Integrating remote sensing and spatially explicit epidemiological modeling

Flavio Finger, Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Marino Gatto, Allyn Christine Knox

Mathematical models of cholera dynamics can not only help in identifying environmental drivers and processes that influence disease transmission, but may also represent valuable tools for the prediction of the epidemiological patterns in time and space as ...

Optimizing a remotely sensed proxy for plankton biomass in Lake Kivu

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Allyn Christine Knox

Many regions of the world, including inland lakes, present with suboptimal conditions for the remotely sensed retrieval of optical signals, thus challenging the limits of available satellite data-processing tools, such as atmospheric correction models (ACM ...

Light and hydrologic variability as drivers of stream biofilm dynamics in a flume experiment

Andrea Rinaldo, Enrico Bertuzzo, Serena Ceola, Lorenzo Mari, Marino Gatto, Gianluca Botter, Tom Ian Battin

We run a comparative study of the results of flume experiments and several dynamic models reproducing the effects of streamflow variability on biofilm (i.e. periphyton) temporal dynamics. During the experiment, two contrasting flow regimes, characterised b ...

Hydrologic Variability Affects Invertebrate Grazing on Phototrophic Biofilms in Stream Microcosms

Andrea Rinaldo, Enrico Bertuzzo, Serena Ceola, Lorenzo Mari, Gianluca Botter, Tom Ian Battin

The temporal variability of streamflow is known to be a key feature structuring and controlling fluvial ecological communities and ecosystem processes. Although alterations of streamflow regime due to habitat fragmentation or other anthropogenic factors ar ...

Spatially Explicit Conditions for Waterborne Pathogen Invasion

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Righetto, Lorenzo Mari, Marino Gatto

Waterborne pathogens cause many possibly lethal human diseases. We derive the condition for pathogen invasion and subsequent disease outbreak in a territory with specific, space-inhomogeneous characteristics (hydrological, ecological, demographic, and epid ...

Rainfall mediations in the spreading of epidemic cholera

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Righetto, Lorenzo Mari, Marino Gatto

Following the empirical evidence of a clear correlation between rainfall events and cholera resurgence that was observed in particular during the recent outbreak in Haiti, a spatially explicit model of epidemic cholera is re-examined. Specifically, we test ...

Biophysical controls on cluster dynamics and architectural differentiation of microbial biofilms in contrasting flow environments

Andrea Rinaldo, Enrico Bertuzzo, Samir Suweis, Lorenzo Mari, Tom Ian Battin

Ecology, with a traditional focus on plants and animals, seeks to understand the mechanisms underlying structure and dynamics of communities. In microbial ecology, the focus is changing from planktonic communities to attached biofilms that dominate microbi ...

Modelling cholera epidemics: the role of waterways, human mobility and sanitation

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Righetto, Lorenzo Mari, Marino Gatto

We investigate the role of human mobility as a driver for long-range spreading of cholera infections, which primarily propagate through hydrologically controlled ecological corridors. Our aim is to build a spatially explicit model of a disease epidemic, wh ...

Hydroclimatology of dual-peak annual cholera incidence: Insights from a spatially explicit model

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Righetto, Lorenzo Mari, Marino Gatto

Cholera incidence in some regions of the Indian subcontinent may exhibit two annual peaks although the main environmental drivers that have been linked to the disease (e.g., sea surface temperature, zooplankton abundance, river discharge) peak once per yea ...

Reassessment of the 2010-2011 Haiti cholera outbreak and rainfall-driven multiseason projections

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Righetto, Melanie Blokesch, Lorenzo Mari, Marino Gatto

Mathematical models can provide key insights into the course of an ongoing epidemic, potentially aiding real-time emergency management in allocating health care resources and by anticipating the impact of alternative interventions. We study the ex post rel ...

On species persistence-time distributions

Andrea Rinaldo, Enrico Bertuzzo, Samir Suweis, Lorenzo Mari, Amos Maritan

We present new theoretical and empirical results on the probability distributions of species persistence times in natural ecosystems. Persistence times, defined as the timespans occurring between species' colonization and local extinction in a given geogra ...

The role of aquatic reservoir fluctuations in long-term cholera patterns

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Righetto, Lorenzo Mari, Marino Gatto

We propose and analyze an important extension of standard cholera epidemiological models, explicitly accounting for fluctuations of water availability to the human community under study. The seasonality of water input in the reservoir drives the variation ...
