communicable disease
传染病

Definitions

a disease whose causative agents may pass or be carried from one person to another directly or indirectly. Modes of transmission include (1) direct contact with body excreta or discharges from an ulcer, open sore, or respiratory tract; (2) indirect contact with inanimate objects such as drinking glasses, toys, or bedclothing; and (3) vectors such as flies, mosquitoes, or other insects capable of spreading the disease. For special precautions to prevent the spread of communicable disease, see isolation. Called also contagious disease.
any disease that is transmissible by infection or contagion directly or through the agency of a vector.
any disease transmitted from one person or animal to another directly, by contact with excreta or other discharges from the body; indirectly, by means of substances or inanimate objects, such as contaminated drinking glasses, toys, or water; or by means of vectors, such as flies, mosquitoes, ticks, or other insects. Communicable diseases may be caused by bacteria, chlamydia, fungi, parasites, rickettsiae, and viruses. To control a communicable disease, it is important to identify the organism, prevent its spread to the environment, protect others against contamination, and treat the infected person. Many communicable diseases, by law, must be reported to the local health department. Also called contagious disease.
