A disease that can spread from one person or species to another is called

• A. Communicable diseases
• B. Infectious diseases
• C. Pathogen
• D. Contamination

Answer: (A)

The concept being tested is whether a disease can be transmitted from one host to another. A disease that can spread from one person or species to another is called a communicable disease. This term specifically indicates the ability to be transmitted between hosts, whether directly through touch or indirectly via vectors or the environment. In contrast, infectious diseases are caused by pathogens, but not all infectious diseases are easily transmitted between individuals, so that term doesn’t by itself denote transmission between hosts. A pathogen is the organism that causes disease, not a description of a disease’s ability to spread. Contamination refers to the presence of harmful agents on surfaces or materials, not the disease’s capacity to move from one host to another. So the best term for a disease that can spread between hosts is communicable disease.
