# Zoonosis **Entity class:** Epidemiological concept A **zoonosis** is an infection or disease transmitted between nonhuman animals and people. Human-to-human ideological or behavioral diffusion is not zoonotic merely because humans are animals in biological taxonomy; the appropriate terms are social contagion, complex contagion, information diffusion, behavioral epidemiology, or violence epidemiology. ## Relationships [[wiki/Network Epidemiology|Network Epidemiology]] · [[wiki/Social Contagion|Social Contagion]] · [[wiki/Pathogen Analogy Boundary|Pathogen Analogy Boundary]] · [[wiki/Counterterrorism Collection - Public Health and Violence Prevention|Public Health and Violence Prevention]] ## Sources - [CDC — About Zoonotic Diseases](https://www.cdc.gov/one-health/about/about-zoonotic-diseases.html) **As of:** 2026-09-23
