Rabies in Iowa and the Upper Midwest: What a Rural Practitioner Should Know
A thorough history of rabies in the United States has been written by Steele,1 who begins by writing that the first reference to rabies in the United States occurred, in dogs, in Virginia and North Carolina, in 1753 and 1762, respectively. An outbreak that occurred in Boston and other North American towns in 1768 is considered the first major epizootic in North America. Canine madness, as it was called, raged allover colonial North America throughout the late 1700\u27s. Rabies reappeared in the eastern US in 1810 and in Ohio assumed an epizootic character affecting dogs, foxes, and wolves. Steele goes on to report that, following the Civil War, rabies was widespread across most of the USA. Mad dogs were reported in many urban as well as rural areas. Sylvatic rabies was recognized in the eastern US in the 18th century, and in the 19th century the disease was seen in foxes throughout the eastern part of the country

Monitoring and modeling of household air quality related to use of different Cookfuels in Paraguay.
In Paraguay, 49% of the population depends on biomass (wood and charcoal) for cooking. Residential biomass burning is a major source of fine particulate matter (PM2.5 ) and carbon monoxide (CO) in and around the household environment. In July 2016, cross-sectional household air pollution sampling was conducted in 80 households in rural Paraguay. Time-integrated samples (24 hours) of PM2.5 and continuous CO concentrations were measured in kitchens that used wood, charcoal, liquefied petroleum gas (LPG), or electricity to cook. Qualitative and quantitative household-level variables were captured using questionnaires. The average PM2.5 concentration (μg/m3 ) was higher in kitchens that burned wood (741.7 ± 546.4) and charcoal (107.0 ± 68.6) than in kitchens where LPG (52.3 ± 18.9) or electricity (52.0 ± 14.8) was used. Likewise, the average CO concentration (ppm) was higher in kitchens that used wood (19.4 ± 12.6) and charcoal (7.6 ± 6.5) than in those that used LPG (0.5 ± 0.6) or electricity (0.4 ± 0.6). Multivariable linear regression was conducted to generate predictive models for indoor PM2.5 and CO concentrations (predicted R2 = 0.837 and 0.822, respectively). This study provides baseline indoor air quality data for Paraguay and presents a multivariate statistical approach that could be used in future research and intervention programs

Near-term Health Benefits of Greenhouse Gas Reductions: A Proposed Assessment Method and Application in Two Energy Sectors of China
This is a study of projected near-term health benefits associated with greenhouse (GHG) reductions resulting from changes in energy efficiency and structure of energy use in the power and household sectors of China. The work was commissioned by the former Office of Global and Integrated Environmental Health at WHO, in order to explore the scope for modelling in the assessment of such short-term health benefits. China was selected as an appropiate case study for this work, as it fulfilled most of the criteria required, including the fact that it is a large country, with data sets available on air pollution and health, and with information on projected trends in the consumption of fossil fuel
