What are the routes of transmission for an infectious disease?

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 are the 3 main routes of infection?
