Mosquitoes and mosquitoborne disease transmission
are sensitive to hydrologic variability. If local hydrologic
conditions can be monitored or modeled at the scales at
which these conditions affect the population dynamics of
vector mosquitoes and the diseases they transmit, a means
for monitoring or modeling mosquito populations and mosquitoborne
disease transmission...
We modeled surface wetness at high resolution, using a dynamic hydrology model, to predict flood and
swamp water mosquito abundances. Historical meteorologic data, as well as topographic, soil, and vegetation
data, were used to model surface wetness and identify potential fresh and swamp water breeding habitats
in two northern New...
We used a dynamic hydrology model to simulate water table depth (WTD) and quantify the relationship
between Saint Louis encephalitis virus (SLEV) transmission and hydrologic conditions in Indian River
County, Florida, from 1986 through 1991, a period with an SLEV epidemic. Virus transmission followed
periods of modeled drought (specifically low...
Disease transmission forecasts can help minimize
human and domestic animal health risks by indicating
where disease control and prevention efforts should be
focused. For disease systems in which weather-related
variables affect pathogen proliferation, dispersal, or transmission,
the potential for disease forecasting exists. We
present a seasonal forecast of St. Louis...
Introduction: Policies and practices in schools may create environments that encourage and reinforce healthy behaviors and are thus a means for stemming the rising rates of childhood obesity. We assessed the effect of a 2005 statewide school physical activity and nutrition mandate on policies and practices in middle and high...
The increased severity of Clostridium difficile infection is primarily attributed to the appearance of an epidemic strain characterized as PCR ribotype 027. The only report that identified epidemic C. difficile ribotype 027 in an American country outside of North America comes from Costa Rica, raising the possibility that strains 027...
Introduction: The health benefits of physical activity are well established in older adults with arthritis. Despite these benefits, many older adults with arthritis are not active enough to maintain health; therefore, increasing physical activity in adults with arthritis is a public health priority. The purpose of this study was to...
On January 5, 2000, the National Institute for Occupational Safety and Health (NIOSH) received a request for a health hazard evaluation (HHE) from the United States Forest Service (USFS), Region 6, Office of Natural Resources. The request listed nausea, rashes, headaches, and dizziness as symptoms reported by Foresters who use...
