Indirect transmission refers to the transfer of an infectious agent from a reservoir to a host by suspended air particles, inanimate objects (vehicles), or animate intermediaries (vectors).

Is contaminated food direct or indirect?

Indirect contact transmission occurs when there is no direct contact between carriers of infection and newly infected persons, for example, via contaminated water or contaminated food.

What is indirect contact for infectious diseases?

Indirect person-to-person transmission occurs when the original host sheds pathogens into the air, water, food or objects in the environment, which then infect someone else (Figure 6). Figure 6 There are many routes for indirect person-to-person transmission of infection.

Examples of direct contact are touching, kissing, sexual contact, contact with oral secretions, or contact with body lesions.

What are the 5 methods of disease 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.
