2020年6月16日 · The term modes of transmission refer to how an infectious agent, also called a pathogen, can be transferred from one person, object, or animal, to another. Viruses, bacteria, parasites, or...

More specifically, transmission occurs when the agent leaves its reservoir or host through a portal of exit, is conveyed by some mode of transmission, and enters through an appropriate portal of entry to infect a susceptible host. This sequence is sometimes called the chain of infection.

2023年8月3日 · There are different classifications for modes of transmission. Diseases can be transmitted directly or indirectly. Direct transmission is the immediate transfer of the infectious agent from an infected host or reservoir to an appropriate entry point through which human infection can take place.

There are two major modes of transmission of diseases, namely direct and indirect modes. Explore how each mode works in detail as well as in tabular form.

Modes of Direct Transmission. Direct physical contact between the skin or mucosa of an infected person and that of a susceptible individual allows direct transfer of infectious agents. This is a mode of transmission for most STIs and many other infectious agents, such as bacterial and viral conjunctivitis (a.k.a. pink eye) and Ebola virus disease.

Understanding how infectious pathogens spread is critical to preventing infectious disease. Many pathogens require a living host to survive, while others may be able to persist in a dormant state outside of a living host.

In medicine, public health, and biology, transmission is the passing of a pathogen causing communicable disease from an infected host individual or group to a particular individual or group, regardless of whether the other individual was previously infected. [1] .
