“…For example, the estimated equine West Nile Virus attack rate in Texas (USA) was best described by environmental features such as lakes, forests and cultivated areas . Highly pathogenic avian influenza H5N1 occurrence has been associated with road connectivity in Romania (Ward et al, 2008a). Similarly, land use and demographic data were used to predict large or small raccoon rabies epizootics in the US (Jones et al, 2003).…”

Available online at: http://www.sciencedirect.com/science/article/pii/S0167587712001420 AbstractAnthropogenic and environmental factors were assessed as predictors of sub-districts in Bhutan that reported rabies in domestic animals during the period 1996−2009. Rabies surveillance data were retrieved from the Veterinary Information System database. Anthropogenic and environmental information were obtained from public data sources. Using the total number of rabies cases reported in domestic animals, the 205 sub-districts of Bhutan were categorized as those sub-districts that reported rabies and those that did not report rabies (n=146). Logistic regression models were fit to the data and odds ratios and 95% confidence intervals were estimated. Sub-districts that share a border with India (OR 10.43; 95% CI: 4.42-24.64; P<0.001); sub-districts connected by major roads (OR 3.09; 95% CI: 1.24-7.68; P=0.015); and greater human population density (OR 3.26; P=0.003) were significantly associated with a sub-district reporting animal rabies in Bhutan during 1996−2009. Results suggest that human population characteristics play an important role in rabies occurrence.

“…HPAI H5N1-infected migratory birds have been found in several European countries, but local outbreaks were smaller in size and intensity compared with the situation observed in China and Southeast Asia (Globig et al, 2009;Ward et al, 2008). This pattern suggests that some wild birds are able to spread AIVs over long distances to previously unaffected areas (Olsen et al, 2006).…”

a b s t r a c tMigratory birds are considered to have played an important role in the spread of highly pathogenic avian influenza H5N1. However, how bird species are expected to modify their wintering sites in response to climate change, and in turn affect the geographic distribution of the risk associated with H5N1 outbreaks, is unknown. We explored the association between past climate variability and H5N1 outbreaks that were attributed to migratory birds from 2005 to 2009. We then predicted the distribution of risk associated with H5N1 outbreaks based on future climate change scenarios. Overlapping the probabilities of bird distribution and H5N1 outbreaks produced final emergence risk. Our results suggest that minimum daily temperature in the winter (−15 to -11 • C, 15 to 17 • C) and maximum daily temperature in the summer (12 to 15 • C, 30 to 35 • C) governed wild bird migratory routes, while high mean air pressure and low mean specific humidity in the winter impacted the outbreaks of H5N1 among migratory birds. By the end of 2030, Europe may be at higher risk for H5N1 outbreaks in January and February. Northern Africa and Southern and Western Asia will likely be a higher risk for H5N1 outbreaks from April to June. Our findings suggest a potential shift in H5N1 risk from Southeast Asia to the western part of the world due to climate change. The results of this study could be used to inform policy in the area of H5N1 outbreak detection and preparedness.
