Which of the following are examples of a reservoir in the chain of infection?

Common reservoirs for infectious agents include humans, animals, insects, objects, substances and the environment.

What is the incubation stage of infection?

Incubation period: In medicine, the time from the moment of exposure to an infectious agent until signs and symptoms of the disease appear. For example, the incubation period of chickenpox is 14-16 days. In biology, the incubation period is the time needed for any particular process of development to take place.

What are the 5 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 common method of disease transmission?

Contact transmission is the most common form of transmitting diseases and virus. There are two types of contact transmission: direct and indirect. Direct contact transmission occurs when there is physical contact between an infected person and a susceptible person.

How do you break the causative agent?

Ways to break the Chain of Infection:immunization against infectious diseases.early diagnosis of infectious diseases.isolation of persons suffering from infectious diseases.collection and disposal of waste in communities.provision of a pure water supply.adequate drainage and sewerage facilities.standard precautions.More items…

What does the chain of infection represent?

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.

What three main elements make up the chain of infection?

One of the basic infection control principles is the chain of infection. Transmission of infection in a hospital requires at least three elements: a source of infecting microorganisms, a susceptible host and a means of transmission for bacteria and viruses.

What are the 3 methods of infection control?

There are three types of transmission-based precautions: contact, droplet, and airborne. Contact precautions are used in addition to standard precautions when caring for patients with known or suspected diseases that are spread by direct or indirect contact.

What is the correct order of the chain of infection?

The six links include: the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. The way to stop germs from spreading is by interrupting this chain at any link.

What is disease process?

Diseases are generally understood to be medical conditions that involve a pathological process associated with a specific set of symptoms. Localized diseases affect specific parts of the body; disseminated diseases spread to other parts of the body; and systemic diseases affect the entire body.

What are the four elements in the chain of infection?

It is a process that begins when (1) an infectious agent or pathogen (2) leaves its reservoir, source, or host through (3) a portal of exit, (4) is conveyed by some mode of transmission, (5) enters the host through an appropriate portal of entry, and (6) infects a susceptible host.

What are 6 ways health care providers can interrupt the chain of infection?

No matter the germ, there are 6 points at which the chain can be broken and a germ can be stopped from infecting others. The 6 points include: the infectious agent, reservoir, portal of exit, means of transmission, portal of entry, and susceptible host.

How do you break a chain of reservoir?

Ways to break the Chain of Infection:elimination of sources of infection (reservoirs)appropriate handling and disposal of body secretions vomitus, faeces, sputum, blood and body fluids.appropriate handling of contaminated items, segregation of waste categories and disposal.
