These diseases spread depends on the specific disease or infectious agent. Some ways in which communicable diseases spread are by:
1) Physical contact with an infected person, such as through touch (staphylococcus), sexual intercourse, fecal/oral transmission (hepatitis A), or droplets (influenza, TB)
2) Contact with a contaminated surface or object (Norwalk virus), food (salmonella, E. coli), blood (HIV, hepatitis B), or water (cholera);
3) Bites from insects or animals capable of transmitting the disease (mosquito: malaria and yellow fever; flea: plague); and
4) Travel through the air, such as tuberculosis or measles.
