“…6,9,10 In Mexico, the transmission of rabies between carnivore species and bats does not appear to be a frequent occurrence, 2 but this assessment may be biased towards vampire bats because of the economic impact to the livestock industry. 11,12 Annual losses to rabies in the livestock industry are estimated at more than $23,000,000.00 US dollars (NOM-067-ZOO-2007) 11 and effective management requires epidemiological surveillance and weekly notifications to the National Epidemiological Surveillance System (SIVE) and the National Service of Agro-Alimentary Health, Safety and Quality (Senasica). In 2012, the national campaign against bovine paralytic rabies assisted 1 112 bovine farms that reported bat attacks, with 360 confirmed rabies cases in cattle.…”

Climate change may modify the spatial distribution of reservoirs hosting emerging and reemerging zoonotic pathogens, and forecasting these changes is essential for developing prevention and adaptation strategies. The most important reservoir of bovine paralytic rabies in tropical countries, is the vampire bat (Desmodus rotundus). In Mexico, the cattle industry loses more than $2.6 million US dollar, annually to this infectious disease. Therefore, we predicted the change in the distribution of D. rotundus due to future climate change scenarios, and examined the likely effect that the change in its distribution will have on paralytic rabies infections in Mexico. We used the correlative maximum entropy based model algorithm to predict the potential distribution of D. rotundus. Consistent with the literature, our results showed that temperature was the variable most highly associated with the current distribution of vampire bats. The highest concentration of bovine rabies was in Central and Southeastern Mexico, regions that also have high cattle population densities. Furthermore, our climatic envelope models predicted that by 2050-2070, D. rotundus will lose 20 % of its current distribution while the northern and central regions of Mexico will become suitable habitats for D. rotundus. Together, our study provides an advanced notice of the likely change in spatial patterns of D. rotundus and bovine paralytic rabies, and presents an important tool for strengthening the National Epidemiological Surveillance System and Monitoring programmes, useful for establishing holistic, long-term strategies to control this disease in Mexico.

“…In contrast, the major direct costs arising from factors such as PEP and livestock deaths have been characterized in numerous studies (Shwiff et al, 2007;Sterner et al, 2009;Zinsstag et al, 2009 ). Canine rabies also has indirect costs, including vaccination of livestock and companion animals and testing of dogs suspected of rabies (Anderson et al, 2012;Narrod et al, 2012 ). Other impacts of rabies on the broader economy can be captured by examining changes in different sectors that result from the direct and indirect impacts of the disease (Diao et al, 2009 ).…”

Potential economic benefits of eliminating canine rabies

Although canine rabies has been eliminated from industrialized countries, infected dogs remain the primary source of human and livestock exposures in Asia, Africa and much of South America. Human deaths are the most important direct economic impact of canine rabies, followed by livestock losses and the cost of PEP, while expenses associated with dog vaccination and control are major indirect impacts. The global burden of rabies disproportionately affects Asia, which experiences more than half of human rabies deaths and approximately 65% of livestock losses, and performs more than 90% of postexposure prophylaxis (PEP). Africa is second to Asia in terms of human deaths and livestock losses, but administers the least number of PEPs of the three regions. Recent experience in Latin America shows that efforts to reduce human deaths from rabies through expanded dog vaccination and improved access to PEP result in significant monetary savings. The elimination of canine rabies would lead to major economic benefits in developing countries that are often the least capable of dealing with the disease. This article forms part of a symposium in Antiviral Research on the elimination of canine rabies.

“…On the other hand, the difference between the estimated and the observed richness indicates the sampling effort performed was not sufficient, as we surveyed only 67% of the richness predicted by Chao 1. For instance, despite the presence of cattle, frequently attractive to hematophagous bats (Anderson et al, 2012), no Desmodontinae bat was captured in our study.…”
