What is the term for the transmission of diseases from animals or insects?

The term for the transmission of diseases from animals or insects is known as zoonoses. Zoonoses encompass a wide range of diseases that can be transmitted from animals, including wildlife and domestic pets, to humans. These diseases can be caused by viruses, bacteria, parasites, or fungi and can result in various health issues in humans. Understanding zoonoses is crucial for public health, especially for individuals who work closely with animals.

The other choices pertain to different medical terms that do not relate to the transmission of diseases from animals or insects. For example, ovarian cyst refers to a fluid-filled sac in the ovary, which is not related to disease transmission. A cyst generally describes a closed sac-like structure filled with liquid or semi-solid material but lacks the context of disease transmission. Hemorrhoids are swollen veins in the rectal area and are also unrelated to zoonotic diseases. Each of these terms represents a distinct medical condition or concept, making zoonoses the correct term for the question posed.
