A contagious infection or disease is a disease that can be passed from one person to another through contact or even being at a close proximate to a person who has the disease. Communicable disease is a disease that can be passed from on person to another but only in the presence of an infectious bacteria or a virus. A non-communicable disease is a disease that is not transferable from one person to another, in other words, non-communicable disease is not transmissible.
