What type of disease is caused by parasites like lice and mites?

The correct answer identifies that lice and mites are parasites, which specifically categorize them as causing parasitic diseases. These types of diseases occur when organisms like lice or mites invade a host, living off its tissues or bodily fluids and often causing symptoms such as itching, inflammation, or secondary infections as the body reacts to the parasite.

Parasitic diseases encompass a wide range of conditions resulting from the presence of parasites, including those that affect the skin or hair, which are commonly associated with lice and mites. Understanding this classification is important in the field of health and wellness because it helps professionals recognize how to treat and manage such infestations effectively.

The other options, such as occupational, viral, and fungal diseases, refer to different mechanisms of disease causation, further distinguishing them from parasitic diseases.
