Waterborne virus transport and the associated risks in a large lake

Tamar Kohn, Xavier Fernandez Cassi, Chaojie Li, Timothy R. Julian

Waterborne enteric viruses in lakes, especially at recreational water sites, may have a negative impact on human health. However, their fate and transport in lakes are poorly understood. In this study, we propose a coupled water quality and quantitative mi ...

Health risks for sanitation service workers along a container-based urine collection system and resource recovery value chain

Tamar Kohn, Simon Schindelholz, Timothy R. Julian

Container-based sanitation (CBS) within a comprehensive service system value chain offers a low-cost sanitation option with potential for revenue generation, but may increase microbial health risks to sanitation service workers. This study assessed occupat ...

High time-resolution simulation of E. coli on hands reveals large variation in microbial exposures amongst Vietnamese farmers using human excreta for agriculture

Ana Karina Pitol Garcia, Timothy R. Julian

Infectious disease transmission is frequently mediated by the environment, where people's movements through and interactions with the environment dictate risks of infection and/or illness. Capturing these interactions, and quantifying their importance, off ...

Pathogens and pharmaceuticals in source-separated urine in eThekwini, South Africa

Tamar Kohn, Linda Strande, Kai Udert, Christa McArdell

In eThekwini, South Africa, the production of agricultural fertilizers from human urine collected from urine-diverting dry toilets is being evaluated at a municipality scale as a way to help finance a decentralized, dry sanitation system. The present study ...

Rainfall mediations in the spreading of epidemic cholera

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Lorenzo Righetto, 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 ...

Spatially Explicit Conditions for Waterborne Pathogen Invasion

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Lorenzo Righetto, 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 ...

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

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Lorenzo Righetto, 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 ...

Integrated water resources management : limits and potential in the municipality of El Grullo, Mexico

Cherryl André de la Porte

Decreasing water availability per capita in more and more countries is the result of bad management over the past centuries. The 'world water crisis', however, is not inevitable. The concept of Integrated Water Resources Management (IWRM) has been promoted ...
