Three things are necessary for an infection to occur:

  • Source: Places where infectious agents (germs) live (e.g., sinks, surfaces, human skin)
  • Susceptible Person with a way for germs to enter the body.
  • Transmission: a way germs are moved to the susceptible persont.

    What are the four things which need to be present to spread a communicable disease?

    A communicable disease is one that is spread from one person to another through a variety of ways that include: contact with blood and bodily fluids; breathing in an airborne virus; or by being bitten by an insect.

    What are communicable diseases How do they spread?

    Communicable diseases are illnesses caused by viruses or bacteria that people spread to one another through contact with contaminated surfaces, bodily fluids, blood products, insect bites, or through the air. There are many examples of communicable diseases.

    What are the factors of communicable diseases?

    Key risk factors for communicable diseases identified in the academic literature can be broadly grouped into categories such as Water, Sanitation and Hygiene (WASH), health and public health system, environment, humanitarian response, infrastructure, insecurity, living conditions, nutrition, mass population …

    What are the 5 stages of communicable diseases?

    The five periods of disease (sometimes referred to as stages or phases) include the incubation, prodromal, illness, decline, and convalescence periods (Figure 2).

        What are the 6 chain of infection?

        The 6 points include: the infectious agent, reservoir, portal of exit, means of transmission, portal of entry, and susceptible host. The way to stop germs from spreading is by interrupting the chain at any link. The host is any carrier of an infection or someone at risk of infection.

        What are stages of infection?

        The five periods of disease (sometimes referred to as stages or phases) include the incubation, prodromal, illness, decline, and convalescence periods (Figure 2). The incubation period occurs in an acute disease after the initial entry of the pathogen into the host (patient).

        What is the most effective way to break the chain of infection?

        Break the chain by cleaning your hands frequently, staying up to date on your vaccines (including the flu shot), covering coughs and sneezes and staying home when sick, following the rules for standard and contact isolation, using personal protective equipment the right way, cleaning and disinfecting the environment.

        What are the three main routes of transmission?

        The transmission of microorganisms can be divided into the following five main routes: direct contact, fomites, aerosol (airborne), oral (ingestion), and vectorborne. Some microorganisms can be transmitted by more than one route.
