Virchow Revisited: Emerging Zoonoses
نویسنده
چکیده
T he German physician Rudolf Virchow (1821–1905) was studying Trichinella in 1855 when he coined the term “zoonosis.” His work on this disease helped to convince him of the importance of linking human and veterinary medicine, something he emphasized throughout his career. Although Virchow is more widely heralded for his cell theory of disease, perhaps his concept of one medicine will become his important legacy. Today, our renewed emphasis on disease emergence is blurring the interface between animal and human health, with diseases blending like figures in an Escher drawing. Emerging diseases, a field of biomedicine that began with the discovery of AIDS, continues to expand. Most emerging diseases in humans are zoonotic in origin. AIDS, for example, apparently transferred to humans from primates—specifically, chimpanzees and sooty mangabeys. Virchow could hardly have envisioned how his concept of one medicine would become so central to public health by the third millenium. In the century and a half since Virchow first used the term zoonosis, we have made incredible progress in the biological sciences, including sequencing the human genome and those of many important microbial pathogens. Ironically, while developing an ever-more-sophisticated understanding of the host, its many responses to infectious agents, and their virulence factors, we also are facing a dramatic increase in the number of new diseases affecting that host, with the majority of those diseases originating in animals.

Zoonoses are disease and/or infection naturally transmissible between vertebrate animals and humans. Emerging zoonoses are defined by the WHO/FAO/OIE joint consultation on emerging zoonotic disease held in Geneva, 3-5 may 2004 as "diseases which are newly recognized or newly evolved or that have occurred previously but show an increase in incidence or expansion in geographical, host or vector r...
متن کاملSurveillance, response systems, and evidence updates on emerging zoonoses: the role of one health
Globally, emerging zoonotic diseases are increasing. Existing surveillance systems for zoonoses have substantial gaps, especially in developing countries, and the systems in place in the developed world require improvements. Resources and updates on evidence-based practice (EBP) for zoonoses are sparser in the veterinary literature as compared to the medical literature. Evidence updates for eme...
متن کاملEmerging or re-emerging bacterial zoonoses: factors of emergence, surveillance and control.
Surveillance and control of emerging bacterial zoonoses is essential in order to prevent both human and animal deaths and to avoid potential economic disorders created by trade barriers or a ban on free circulation of human or animal populations. An increased risk of exposition to zoonotic agents, the breakdown of the host's defenses, the emergence of bacterial strains resistant to antibiotics ...
متن کاملRudolf Virchow
Virchow was one of the 19th century’s foremost leaders in medicine and pathology. He was also a public health activist, social reformer, politician, and anthropologist. Virchow was the only child of a farmer and city treasurer in Schivelbein, Germany. He had a strong interest in natural science. In 1839, he received a scholarship from the Prussian Military Academy, where he was given the opport...
