One Health in allergology: A concept that connects humans, animals, plants, and the environment.

Abstract

One Health is "a collaborative effort of multiple disciplines - working locally, nationally, and globally - to attain optimal health for people, animals, and the environment", the so-called One Health triad1 (Fig. 1).Historically, aspects of One Healthwere already discussed in the fourth century by Hippocrates, who realized that a clean environment is very important for human health1 . More recently, Rudolf Virchow (1821-1902) coined the term "zoonosis" in 1880and fathered modern One Healthin the sense of OneMedicine by strongly supporting the view of human and animal health being linked to each other.1.
