Anthroponoses refer to diseases which are transmitted from human beings to other human beings.
Examples of anthroponoses include: HIV/AIDS, Measles, and Tuberculosis.
These diseases are typically spread through various methods such as contact with body fluids, airborne droplets, or direct human contact.
Importantly, control and prevention of anthroponoses usually involve breaking the chains of human transmission.

Zoonoses are infectious diseases that are transmitted from animals (both wild and domesticated) to humans.
Examples of zoonoses include: Rabies, Lyme disease, and Ebola.
Zoonoses are often transmitted via vectors (such as ticks or mosquitoes), through direct contact with animals or their excrements, or by eating contaminated food.
Key to controlling zoonoses is the health management of animal populations and precautions taken by humans when interacting with animals.

Sapronoses are infectious diseases that originate from soil, water, or decaying organic matter.
Examples of sapronoses include: Mucormycosis (a fungal infection) and Legionnaire’s disease.
These diseases do not require an intermediary host or vector and are not usually transmitted from human to human or animal to human.
Preventative strategies against sapronoses include environmental control measures and personal protective equipment for individuals at risk.
