Wenwu Yin and co-workers conducted a systematic review on challenges and needs to eliminate rabies in China (Yin et al., 2013 in this journal). Their analysis shows that there is considerable overrepresentation of laboratory and basic epidemiology research. On the other hand, information on effective control activities and policies are nearly absent. Currently we know enough to control and eliminate dog rabies effectively. Continuing basic research while not engaging in the control of rabies appears almost cynical. Why is it not attractive to do research on effective control and elimination? Let us move now from the biological understanding to the science of rabies elimination.

Scientific inquiry generates new knowledge and establishes an evidence-base on which modern society relays for informed decisions and, ultimately, action . Currently there is an exponential growth of accumulated knowledge, making it harder and harder to reach the edge of understanding, also coined “the burden of knowledge” (Benjamin Jones, Northwestern University, Chicago IL, USA, unpublished). One would argue that with so much accumulated knowledge and an ever deeper understanding, its translation into action and improvement of human health and wellbeing would be accelerated. However, there is a huge, and perhaps widening gap between knowledge and action, or rather the lack thereof. This issue is convincingly documented by Wenwu Yin and co-workers, who conducted a systematic review and analysed the scientific literature on rabies in the People’s Republic of China to examine challenges and needs to eliminate rabies in the country ( in this journal).
However, why is there no or insufficiently effective action to control and eliminate dog rabies? Yin’s paper, based on a systematic analysis of published literature and official documents shows that there is considerable overrepresentation of laboratory investigations or pathogen-associated and basic epidemiology research. On the other hand, information on effective control activities and policies are nearly absent. There is a lack of awareness in the general population about rabies and how to handle exposure to rabies suspected dog bites. Albeit some progress, there is still a lack of standardization of post exposure treatment in China, making it the worlds largest market for human rabies vaccination with no effect on interrupting transmission. Such practices benefit large drug companies but not the poor dwellers, who have to spend the equivalent of several months income on the cost of post exposure prophylaxis. Surveillance in dogs and in humans reports a fraction of the suspected numbers of cases and there is still a lack of communication between the public health and veterinary sector on the subject. Why is it not attractive to do research on effective control and elimination? Rolling out large-scale campaigns against dog rabies is as complex as systems biology at the subcellular level. Reaching sufficient coverage to interrupt virus transmission requires an in-depth understanding of delivery, availability, accessibility, affordability, adequacy, acceptability and many other effectiveness factors [8–10]. The article by Yin and co-workers shows an appalling situation of research still focussing on the biology of rabies rather than on the community-effectiveness of interventions. This observation is not unique for rabies, but in the case of rabies it appears almost cynical. There is a huge potential for research into the determinants of how dog rabies can be effectively eliminated. For a broad range of zoonoses and neglected tropical diseases, scientists seem to prefer sophisticated molecular analyses over investigating in effective interventions in communities. Why are research funding agencies much less interested into research aiming at effectiveness determinants rather than the biology of pathogens?
Research should contribute to fill the gap between knowledge and effective action by addressing the social, political, economic and psychological complexity of effective rabies control interventions. This will require that scientists closely collaborate with authorities and communities as partners in a transdisciplinary way [11, 12]. Interestingly, the study of transmission dynamics during elimination yields new insights into fundamental parameters of pathogen virulence. National governments should recognize that freedom of dog rabies is a public good, for which public funds should be invested without delay . Let us move now from the biological understanding to the science of rabies elimination.
