A zoonosis (/ z oʊ ˈ ɒ n ə s ɪ s, ˌ z oʊ ə ˈ n oʊ s ɪ s / ⓘ; [1] plural zoonoses) or zoonotic disease is an infectious disease of humans caused by a pathogen (an infectious agent, such as a bacterium, virus, parasite, or prion) that can jump from a non-human vertebrate to a human. When humans infect non-humans, it is called reverse ...
Cases of tularemia, also known as “rabbit fever," are on the rise in the U.S., according to a new report from the CDC. The report identifies symptoms and the groups most at risk.
Human activity is involved with many emerging infectious diseases, such as environmental change enabling a parasite to occupy new niches. When that happens, a pathogen that had been confined to a remote habitat has a wider distribution and possibly a new host organism. Parasites jumping from nonhuman to human hosts are known as zoonoses. Under ...
C. fetus subspecies fetus is a zoonotic pathogen that has been reported to cause disease in immunocompromised humans. [18] [14] Similar to C. fetus subspecies jejuni, C. fetus subspecies fetus can be acquired via fecal-oral route and resides mostly in the gastrointestinal tract. Other means of transmission include the ingestion of infected ...
Spillover is a common event; in fact, more than two-thirds of human viruses are zoonotic. [4] [5] Most spillover events result in self-limited cases with no further human-to-human transmission, as occurs, for example, with rabies, anthrax, histoplasmosis or hydatidosis. Other zoonotic pathogens are able to be transmitted by humans to produce ...
Several articles, recent to early 2014, warn that human activities are spreading vector-borne zoonotic diseases. [a] Several articles were published in the medical journal The Lancet, and discuss how rapid changes in land use, trade globalization, climate change and "social upheaval" are causing a resurgence in zoonotic disease across the world ...
Similarly, HIV originating in simians (crossover due to humans consuming wild chimpanzee bushmeat) and influenza A viruses originating in avians (crossover due to an antigenic shift) could have initially been considered a zoonotic transference as the infections first came from vertebrate animals, but could currently be regarded as an anthroponosis because of its potential to transfer between ...
Transmission of SARS-CoV-2 from humans to animals, known as reverse zoonosis or anthroponosis, is possible. [64] Reverse zoonotic or experimental infection with SARS-CoV-2 has been reported in 31 animal species. [65] It is not believed that wildlife plays a significant role in the ongoing circulation of SARS-CoV-2 among humans. [66]
