What term describes a disease that can be transmitted directly from one individual or organism to another through contact?

Explanation

The correct term is 'Contagious,' which refers to illnesses that spread through direct contact between individuals. While 'Infectious' diseases can also spread, not all infectious diseases are transmitted by direct contact. 'Universal' means applicable everywhere, 'Deadly' refers to causing death, and 'Non-communicable' diseases cannot be passed from person to person.
