The World Health Organization estimates that 25% of the 57 million annual deaths that occur globall are caused by microbes. A study reported 1 415 species of infectious organisms are known to be pathogenic to humans. Zoonoses constitute 61% of all known infectious diseases, with humans serving as the primary reservoir for only 3% of them. Of the 175 infectious species considered to be emerging, 75% are zoonotic. Zoonotic diseases and their impact on human and animal health are not monitored, prevented, and treated in an integrated way, despite the fact that etiologies and treatments are similar across species. The efficacy and resistance of a drug in one species has a bearing on others, in the context of zoonoses. Further, an RCT involving many species is effective in a natural setting, is robust, and may require fewer human volunteers. One Health is based on a systems approach and a collaborative effort of multiple disciplines – working locally, nationally, and globally – to attain optimal health for people, animals, and the environment. Systematic reviews and meta-analyses have so far been independent and discipline oriented. Pooling of results for diagnostic test accuracies and treatment effects of drugs for zoonoses across species has to be done, since the results of preclinical trials emanate from laboratory animals. The Cochrane Collaboration is the platform of choice to initiate a new group on zoonoses to carry out systematic meta-analyses of diagnostic tests and drug efficacies without bias, thus underpinning the systems approach and One Health.
