Which term describes disease caused by organisms such as lice and mites?

• A. Direct Transmission
• B. Hepatitis
• C. Parasitic Disease
• D. Fungi

Answer: (C)

Parasitic disease describes illnesses caused by organisms that live on or in a host and depend on it for survival. Lice and mites are classic examples of parasites that live on the body and feed on blood or skin, leading to infestations and related symptoms. This term specifically identifies the type of pathogen involved—parasites—rather than how a disease is spread or the specific disease name. That’s why it fits best: it encompasses conditions like lice infestations and mite-related skin problems, rather than referring to viruses like hepatitis, or to fungi, which cause fungal infections. Direct transmission, while important for understanding how diseases spread, is not the designation for the pathogens themselves, and fungi are a different category of organisms. So the description that covers diseases caused by these parasites is parasitic disease.
