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 the four main classes of microorganism?
microorganisms. The four main classes include bacteria, protozoa, fungi, and viruses.
What is the most effective way to prevent infection?
Simply put, yes. Hand washing is the single most effective way to prevent the spread of infections. You can spread certain “germs” (a general term for microbes like viruses and bacteria) casually by touching another person.
What portal means?
(Entry 1 of 3) 1 : door, entrance especially : a grand or imposing one. 2 : the whole architectural composition surrounding and including the doorways and porches of a church. 3 : the approach or entrance to a bridge or tunnel.
How does hand washing break the chain of infection?
Washing your hands with soap and running water loosens, dilutes and flushes off dirt and germs. It’s very important to remember to dry your hands completely after washing. Damp hands pick up and transfer up to 1000 times more bacteria than dry hands.
What disease is associated with bacteria?
Bacteria cause many common infections such as pneumonia, wound infections, bloodstream infections (sepsis) and sexually transmitted diseases like gonorrhea, and have also been responsible for several major disease epidemics.
Is a urinary catheter a portal of entry?
of: Reservoir. Portal of entry. Causative agent. Mode of transmission. A B C D Correct. A urinary catheter acts as a potential entry port for organisms. Incorrect. The correct answer is: A urinary catheter. acts as a potential entry port for organisms. 5. Every time you put on an N95 respirator you.
What are the 5 portals of entry?
Terms in this set (6)skin and mucous membranes. diseases of the skin and mucous membranes frequently enter thru skin principally via cuts and abrasions or may be transferred by the bite of animals and insects.respiratory tract. … digestive tract. … genito-urinary tract. … placenta. … vehicles of exit of pathogen.
What are the 3 major portals of entry for disease?
The human body presents three large epithelial surfaces to the environment—the skin, the respiratory mucosa, and the alimentary tract, and two lesser surfaces—the genital tract and the conjunctiva (Fig.
Is skin a portal of entry?
A portal of entry is the site through which micro-organisms enter the susceptible host and cause disease/infection. Infectious agents enter the body through various portals, including the mucous membranes, the skin, the respiratory and the gastrointestinal tracts.
What are examples of portal of entry?
Portals of entry into the human body include:Inhalation (via the respiratory tract)Absorption (via mucous membranes such as the eyes)Ingestion (via the gastrointestinal tract)Inoculation (as the result of an inoculation injury)Introduction (via the insertion of medical devices)
What are the six elements of the 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.
What is a communicable disease?
Communicable diseases, also known as infectious diseases or transmissible diseases, are illnesses that result from the infection, presence and growth of pathogenic (capable of causing disease) biologic agents in an individual human or other animal host.
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 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 an example of portal of exit?
A portal of exit is the site from where micro-organisms leave the host to enter another host and cause disease/infection. For example, a micro-organism may leave the reservoir through the nose or mouth when someone sneezes or coughs, or in faeces.
Who is susceptible to infection?
A susceptible person is someone who is not vaccinated or otherwise immune, or a person with a weakened immune system who has a way for the germs to enter the body. For an infection to occur, germs must enter a susceptible person’s body and invade tissues, multiply, and cause a reaction.
What is the most common portal of entry?
Mucosal surfaces are the most important portals of entry for microbes; these include the mucous membranes of the respiratory tract, the gastrointestinal tract, and the genitourinary tract.
What is the portal of entry?
The portal of entry refers to the manner in which a pathogen enters a susceptible host. The portal of entry must provide access to tissues in which the pathogen can multiply or a toxin can act. Often, infectious agents use the same portal to enter a new host that they used to exit the source host.
How do you break the portal of entry?
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 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).
