Many of the diseases that affect human beings are contagious. A disease is contagious that may be spread from a person, who has the disease, to others. When on person become ill with a contagious disease, others coming in contact with the sick person are likely to become ill with the same disease. The disease will ‘spread’. When a person is sick with gall-stones, or appendicitis, or pleurisy, or rheumatism those who live in the same house or those who visit the sick person need not fear that they will catch the same disease. These diseases are not contagious. They do not spread. There are other diseases that belong in this group but the ordinary diseases of this type are not numerous.
