What is the portal of entry for the influenza virus?
Influenza transmission occurs when the influenza virus (Infectious Agent), lives and grows in the client’s/patient’s/resident’s lungs and air passages (Reservoir), exits the respiratory tract through coughing and sneezing (Portal of Exit), travels via hands, surfaces and droplets (Mode of Transmission), and gains entry ….
What does Portal mean?
(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 do infections get into the body?
Microorganisms capable of causing disease—pathogens—usually enter our bodies through the mouth, eyes, nose, or urogenital openings, or through wounds or bites that breach the skin barrier. Organisms can spread—or be transmitted—by several routes.
Why do we need to break the chain of infection?
Despite the variety of viruses and bacteria, germs spread from person to person through a common series of events. Therefore, to prevent germs from infecting more people, we must break the chain of infection.
What are the portals 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.
What are the 5 portals of entry?
5. The portal of entryInhalation (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)
Is the placenta a portal of entry?
Portals of Entry and Exit Vertical transmission may occur in the ovum, via the placenta, during birth, or in the colostrum or milk.
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 portal of entry?
Site of entry: oropharynx for some microorganisms ● intestinal tract for most viruses.
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.
What are the 4 types of infections?
This article will focus on the most common and deadly types of infection: bacterial, viral, fungal, and prion.
What is the most effective way to prevent infection?
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 are the different modes of entry of microorganisms into the body?
Microorganisms capable of causing disease—or pathogens—usually enter our bodies through the eyes, mouth, nose, or urogenital openings, or through wounds or bites that breach the skin barrier. Organisms can spread, or be transmitted, by several routes.
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.
What are the 3 main ways infection can get into the body?
Infectious diseases are caused by organisms (germs) such as bacteria, viruses, fungi or parasites….Germs can spread from person to person through:the air as droplets or aerosol particles.faecal-oral spread.blood or other body fluids.skin or mucous membrane contact.sexual contact.
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, …
How do viruses enter the human body?
Humans can become infected by a virus in contaminated food or water. The virus enters the body through the stomach or bowels when the contaminated food or water is swallowed. Viruses spread through food or water often affect the gastrointestinal tract and cause symptoms such as nausea, vomiting, and diarrhea.
Who is most susceptible to influenza?
