Which term describes disease caused by organisms like lice and mites?

• A. Infection
• B. Parasitic Disease
• C. Direct Transmission
• D. Immunity

Answer: (B)

Parasites are organisms that live on or in a host and feed off it. Lice and mites are classic examples of parasites, so when a disease is caused by these organisms, it is described as a parasitic disease. This term specifically names the type of organism involved. In contrast, infection is a broader term for any invasion by a microorganism (bacteria, viruses, fungi, or parasites) and doesn’t specify the organism type. Direct transmission describes how a disease spreads, not what kind of disease it is. Immunity refers to the body's defense against disease. So the best description for diseases caused by lice and mites is parasitic disease.
