The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
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 ...
The monkeypox virus is a zoonotic virus belonging to the genus Orthopoxvirus, which itself is a member of the family Poxviridae (also known as the poxvirus family). [9] Of note, the Orthopoxvirus genus includes the variola virus that prior to eradication via the advent of the smallpox vaccine, was the cause of the infectious human disease known as smallpox. [10]
Toxocariasis is an illness of humans caused by the dog roundworm (Toxocara canis) and, less frequently, the cat roundworm (Toxocara cati). [1] These are the most common intestinal roundworms of dogs, coyotes, wolves and foxes and domestic cats, respectively.
