What is the main route to spread infection?

The Main Routes Infection can Enter the Body are: Body fluids – A body fluid e.g. blood, urine, pus, saliva from one person enters the body of another e.g. through cuts or other means such as sexual intercourse (e.g. syphilis, HIV etc.). Through saliva (e.g. glandular fever).

What is the 3 main route to spread infection?

The transmission of microorganisms can be divided into the following five main routes: direct contact, fomites, aerosol (airborne), oral (ingestion), and vectorborne.

What is the most common route of infection transmission?

Contact is the most frequent mode of transmission of health care associated infections and can be divided into: direct and indirect.

What are the routes of transmission of infection?

What is route of transmission definition?

The pathway of causative agents from a source to infection of a susceptible host is called 'transmission route'. The characteristic of the transmission route depends mainly on the characteristics of the causative agent and those of the host.

How do infections spread?

What is the method of transmission?

A method of transmission is the movement or the transmission of pathogens from a reservoir to a susceptible host. Once a pathogen has exited the reservoir, it needs a mode of transmission to the host through a portal of entry. Transmission can be by direct or indirect contact or through airborne transmission.

What are the most common sources of infection?

Common sources of infection

Sources, e.g. airborne, blood borne, sexually transmitted, fecal, oral, environment, stagnant water, warm-water systems, animals.

Are vectors a main route to spread infection?

The spread of pathogenic microorganisms can occur through different vectors of transmission. These vectors including air, surfaces and water act as a bridge that transports the infectious agents directly or indirectly into humans or living organisms.

What is the source of infection?

We refer to the source of infection as the origin from which a host acquires the infection, either endogenous (i.e. originating from a person's own commensal microbial flora) or exogenous (i.e. an individual, animal or object that in the external environment of the host).

What are the four main modes of transmission?

The modes (means) of transmission are: Contact (direct and/or indirect), Droplet, Airborne, Vector and Common Vehicle.

What are common methods of transmission of diseases?

What are the 4 main causes of infection?
