The term that refers specifically to the ability to transmit a disease from person-to-person is "contagious." This term emphasizes the direct transmission of pathogens through contact, respiratory droplets, or other close interactions between individuals. Contagious diseases can spread rapidly among people, which is a critical factor in managing public health responses during outbreaks.

In contrast, "infectious" refers more broadly to any disease caused by germs, including bacteria, viruses, fungi, or parasites, that can spread in various ways, not solely from person-to-person contact. "Endemic" describes a disease that is consistently present within a particular geographic area or population. It does not inherently imply person-to-person transmission. "Epidemic" refers to a sudden increase in the number of cases of a disease above what is normally expected in a specific area, but it doesn't specifically indicate how the disease spreads. Thus, the term "contagious" precisely captures the essence of direct disease transmission among individuals.
