Transmitted
Transmitted
Transmitted (/trænsˈmɪtɪd/), from the Latin transmittere meaning "to send across or through", is a term used in various fields of medicine to describe the process by which a disease, condition, or infection is spread from one organism to another.
In Medicine
In medicine, the term 'transmitted' is often used to describe the spread of infectious diseases or pathogens. This can occur through various modes of transmission, including direct contact, indirect contact, droplet transmission, airborne transmission, fecal-oral transmission, and vector-borne transmission.
- Direct contact transmission occurs when there is physical contact between an infected person and a susceptible person. Sexually transmitted diseases are examples of diseases transmitted through direct contact.
- Indirect contact transmission involves contact of a susceptible host with a contaminated intermediate object, usually inanimate, such as contaminated instruments or surfaces.
- Droplet transmission involves contact of the conjunctivae or the mucous membranes of the nose or mouth of a susceptible person with large-particle droplets containing microorganisms generated from a person who has a clinical disease or who is a carrier of the disease.
- Airborne transmission occurs when infectious agents are carried by dust suspended in the air. With airborne transmission, the droplets are small enough that they can remain airborne for an extended period.
- Fecal-oral transmission occurs when pathogens in fecal particles pass from one person to the mouth of another person. Main cause of transmission of pathogens like cholera, hepatitis A, and polio.
- Vector-borne transmission occurs when vectors such as mosquitoes, ticks, or fleas take up a pathogen from one host and transmit it to another.
