communicable disease

noun

plural communicable diseases
: an infectious disease (such as cholera, hepatitis, influenza, malaria, measles, or tuberculosis) that is transmissible by contact with infected individuals or their bodily discharges or fluids (such as respiratory droplets, blood, or semen), by contact with contaminated surfaces or objects, by ingestion of contaminated food or water, or by direct or indirect contact with disease vectors (such as mosquitoes, fleas, or mice)
