Operational Risk Assessment Tool for Evaluating Leishmania infantum Introduction and Establishment in the United States through Dog Importation.

International pet travel and commercial operations have increased animal disease importation risks, including for Leishmania infantum, a deadly parasite of humans and domestic dogs. Collaborating as an interdisciplinary working group, we developed an operational tool for veterinary and public health practitioners to assess and manage L. infantum risk in dogs imported to the United States.

Collection of Time Activity Data to Support Exposure Assessment: Protocol for a Systematic Evidence Map.

Background: Time Activity Data (TAD) describe the timing, duration, and/or frequency of human activities. Given that activity dictates the rate of contact a person has with an environmental agent, activity data can be used to derive rigorous estimates of exposure. TAD has been used to support exposure estimation in a variety of contexts, although there has been no systematic characterization of how TAD has been collected for environmental health applications.

Application and demonstration of meso-activity exposure factors to advance estimates of incidental soil ingestion among agricultural workers.

Background: Soil is an understudied and underregulated pathway of chemical exposure, particularly for agricultural workers who cultivate food in soils. Little is known about how agricultural workers spend their time and how they may contact soil while growing food. Exposure factors are behavioral and environmental variables used in exposure estimation.
