The incubation period is the initial stage of the disease process before symptoms become apparent and the pathogen is actively replicating. There are no signs or symptoms during the incubation period. Incubation times vary widely and are influenced by host health, the pathogen transmission route, and the number of pathogens invading.

See Page 1. The extravasation of leukocytes involves four stages. 1 . Margination. Laminar blood flow keeps RBCs in the center of the vessel and pushes WBC to the vessel walls. This allows the leukocytes to have a better opportunity while interacting with the endothelial cell lining. 2.
1. Incubation. The incubation stage includes the time from exposure to an infectious agent until the onset of symptoms. Viral or bacterial particles replicate during the incubation stage.Mar 3, 2021
The infectious disease process includes the following components: (1) agent (2) reservoir (3) portals of entry and exit (4) mode of transmission (5) immunity.Nov 24, 2003
Infection: The invasion and multiplication of microorganisms such as bacteria, viruses, and parasites that are not normally present within the body. An infection may cause no symptoms and be subclinical, or it may cause symptoms and be clinically apparent.
Infectious diseases can be caused by:Bacteria. These one-cell organisms are responsible for illnesses such as strep throat, urinary tract infections and tuberculosis.Viruses. Even smaller than bacteria, viruses cause a multitude of diseases ranging from the common cold to AIDS.Fungi. ... Parasites.Feb 18, 2022
There are five stages (or phases) of a disease. (Hattis, 2020). These stages are (1) Incubation period, (2) Prodromal period, (3) Illness period, (4) Decline period, and (5) Convalescence period.Jan 27, 2022

The six links include: the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host.
An infection occurs when germs enter the body, increase in number, and cause a reaction of the body. 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.
There are four main types of infections: Viral. Bacterial....This can cause symptoms such as fever, headache, and rash.Viral infection. Viruses can cause a wide range of infectious diseases. ... Bacterial infection. ... Fungal infection. ... Parasitic infection.
Portal of exit is the path by which a pathogen leaves its host. The portal of exit usually corresponds to the site where the pathogen is localized.

There are five stages of infection: incubation. prodromal. illness. decline. convalescence. This article will explain each of the five stages of infection in detail, describing how long they can last and giving examples of infections. It will also highlight what the stages of infection are, specifically in people with HIV. 1.
The incubation stage includes the time from exposure to an infectious agent until the onset of symptoms. Viral or bacterial particles replicate during the incubation stage.
Decline. Convalescence. In HIV. Summary. Infection occurs when an organism, such as a virus or bacterium, invades the body. The infectious agent rapidly multiplies in the body’s tissues. Although not all infections result in disease, some can trigger the immune system, causing symptoms of illness.
The duration of the prodromal stage varies depending on the type of infection. For example, the flu has a short incubation period of about 2 days. Trusted Source. . As a result, the prodromal stage may overlap with the incubation stage and the onset of illness. The Centers for Disease Control and Prevention (CDC)
The prodromal stage refers to the period after incubation and before the characteristic symptoms of infection occur. People can also transmit infections during the prodromal stage. During this stage, the infectious agent continues replicating, which triggers the body’s immune response and mild, nonspecific symptoms.
During the decline stage, the immun e system mounts a successful defense against the pathogens, and the number of infectious particles decreases. Symptoms will gradually improve. However, a person can develop secondary infections during this stage if the primary infection has weakened their immune system.
If left untreated, acute HIV infection progresses to chronic HIV, which can last for decades. In chronic HIV, the virus continues to replicate and destroy CD4 cells. People may not experience symptoms at this stage. However, the absence of symptoms does not mean that the infection is gone.
The cycle of infection. a. Infectious Microorganisms (Agent). These are the pathogens that cause communicable diseases. b. Reservoir. The reservoir (source) is the person or animal that has the disease. Sometimes a person may have a disease but is not ill. This type of person is called a carrier.
Prevention and control of infection is of vital importance to the patient as well as to health care personnel. In order to provide proper care for patients with communicable diseases or infectious organisms, you should understand the components of infection and the methods to control the cycle of infection. The cycle of infection (see figure 1-1) ...
Microorganisms leave the body of the infected person by means of droplets exhaled as a spray in coughing, sneezing, talking, or just breathing. Microorganisms also escape. in nose and throat secretions. (1) Wear a mask. (2) Do not talk directly into patient's face.
Gastrointestinal Tract. Microorganisms. that leave the body of the infected person. by means of body secretions, for example, hepatitis, the virus is shed in the stool of the infected person. (1) Handle body secretions properly. (2) Perform patient care handwash. Skin.
Vector. The vector is the connection between the source of the disease (reservoir) and the person who is going to catch the disease (host). The vector is sometimes referred to as the "vehicle of disease transmission.". Vectors and their control are discussed in figure 1-3. VECTORS (MODES OF TRANSFER) CONTROL.
Susceptible Host. The host is the person who gets the disease. Once the host has the disease, he becomes a reservoir for future transmission of the disease. A listing of the most susceptible persons to disease and some control measures are shown in figure 1-5.
Other examples of reservoirs are a person with a common cold, a person with malaria, a person with syphilis, a rat with plague, and a bat with rabies.
Herpes zoster is a reactivation of a previous varicella zoster infection.". When providing care for a child with herpes zoster (shingles), the parents ask the nurse how the child contracted this infectious disorder. Which response by the nurse is most appropriate? • Assess intake and output.
fifth disease. A young client arrives at the clinic with a rash on the trunk and flexor surfaces of the extremities. The mother informs the nurse that the rash started a day before on the exterior surfaces of the extremities; 2 days before, the child had a really bad rash on the face. The physician diagnoses the child with erythema infectiosum.
The nurse is discussing food allergies with parents of a young child. She explains that a very effective way to determine which foods a child may be allergic to is to implement: A nurse is providing care to a child with HIV who is prescribed therapy with a nucleoside reverse transcriptase inhibitor.
The parents tell the nurse that the child's skin seems to be an unusual color. The nurse notes that the child's skin appears bronze-colored and jaundiced.
