What are the 5 modes of transmission?
There are five main routes of disease transmission: aerosol, direct contact, fomite, oral and vector, Bickett-Weddle explained at the 2010 Western Veterinary Conference. Diseases can be spread to humans (zoonotic) by those same five routes.
What is the difference between contagious and infectious?
Infectious diseases are caused by microscopic germs (such as bacteria or viruses) that get into the body and cause problems. Infectious diseases that spread from person to person are said to be contagious. Some infections spread to people from an animal or insect, but are not contagious from another human.
