What are the 4 stages of infectious disease?

To cause disease, a pathogen must successfully achieve four steps or stages of pathogenesis: exposure (contact), adhesion (colonization), invasion, and infection.

How many stages of disease are there?

three stages during disease progression, i.e., normal state, pre-disease state and disease state.

What are the stages of infection process?

If the immune system is able to fight off the pathogen before it can establish an infection, no signs of disease will occur. The infectious disease process is categorized into different stages of infection. Infections generally involve incubation, prodromal, illness, decline, and convalescent stages.

What are the 4 levels of disease prevention?

These preventive stages are primordial prevention, primary prevention, secondary prevention, and tertiary prevention. Combined, these strategies not only aim to prevent the onset of disease through risk reduction, but also downstream complications of a manifested disease.

What do stages mean in diseases?

Disease staging is a clinically based measure of severity that uses objective medical criteria to assess the stage of disease progression. Its availability in automated form increases its ease of implementation in hospital reimbursement and management.

What is the first stage of an infectious disease?

With respect to disease, the incubation period is defined as the time from exposure to an infectious agent until the time of first signs or symptoms of disease. The incubation period is followed by the period of clinical illness which is the duration between first and last disease signs or symptoms.

What are the 5 stages of illness?

Stages of Illness BehaviorStage 1: Symptom Experience. The person is aware that something is wrong. ... Stage 2: Assumption of the Sick People. If symptom persist and become severe, clients assume the sick role. ... Stage 3: Medical Care Contact. ... Stage 4: Dependent Client Role. ... Stage 5: Recovery and Rehabilitation.

What is acute stage of infection?

Acute infections begin with an incubation period, during which the genomes replicate and the host innate responses are initiated. The cytokines produced early in infection lead to classical symptoms of an acute infection: aches, pains, fever, malaise, and nausea.

What are the 7 stages of disease?

Stage One — Enervation. The word enervation comes from the word energy. ... Stage Two – Toxemia (or toxicosis) ... Stage Three — Irritation. ... Stage Four — Inflammation. ... Stage Five — Ulceration. ... Stage Six — Induration. ... Stage Seven — Cancer.

What are the 3 stages of disease in etiology?

They have a bearing on how illness is experienced, how differently it can be perceived at the time of first contact with the health system, and how it may appear at later stages. Opportunities for prevention arise at every stage in the process, and three main levels are described: primary, secondary, and tertiary.

What are the stages of fever?

There are five patterns: intermittent, remittent, continuous or sustained, hectic, and relapsing. With intermittent fever, the temperature is elevated but falls to normal (37.2°C or below) each day, while in a remittent fever the temperature falls each day but not to normal.

What is latent stage of disease?

The latent period of an infectious disease is the time interval between infection and becoming infectious [1]. This can be contrasted with the incubation period, which is the time interval between infection and the appearance of clinical symptoms [1].

Illness periods include incubation period, prodromal period, disease period, decline period, and recovery period.

What are the stages of disease development?

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

What is the clinical stage of a disease?

Medical definition of clinical disease. Clinical disease: disease that has recognizable clinical signs and symptoms, as opposed to subclinical disease, which has no detectable signs and symptoms. Diabetes, for example, may be a subclinical disease for a few years before becoming a clinical disease.

Why does the body get inflamed when it is inflamed?

The area becomes inflamed due to the constant irritation from toxic material.

Why is fever important?

The heat from fever is necessary to accelerate the elimination of toxins. Fever acts as a catalyst, which causes the toxins to be diluted and pass into the blood stream to the bowels, bladder, lungs and skin for elimination. We can see fever in stages 2-7 of disease.

What happens when the lymph nodes become toxic?

When the blood, lymph nodes, and tissues of the body become toxic, the entire body is under stress. Tiredness and sluggishness are symptoms of the onset of this internal bodily stress. This negative physical state directly affects one’s mental and emotional condition, and this shows up as confliction, confusion, depression, lack of will power, and lack of creativity (which is a major concern of employers in the workplace).

How do you know if you are enervated?

Since energy is restored when we sleep, the first warning sign that we are becoming enervated is that we will become tired and sluggish or require naps during the day or more sleep at night. Another sign that the body is in distress (trying to heal itself) is the loss of appetite. This loss of appetite can be seen through all stages of disease.

How long does it take for a disease to progress?

Each stage progresses slowly and in a predictable manner. We can be in one of the stages of disease for weeks, months, or even years before we progress to the next stage. At any time during the first six stages, if the cause is stopped then the disease subsides and our health returns to normal. If drugs are used to stop the pain and discomfort, but avoids curing the underlying problem, then the disease will continue, even though we experience no pain, thus giving the false impression that the disease is diminishing. According to the latest research, here’s how the seven stages of disease progress.

What are the negative effects of physical health?

This negative physical state directly affects one’s mental and emotional condition, and this shows up as confliction, confusion, depression, lack of will power, and lack of creativity (which is a major concern of employers in the workplace).

How long can you be in one of the stages of a disease?

We can be in one of the stages of disease for weeks, months, or even years before we progress to the next stage. At any time during the first six stages, if the cause is stopped then the disease subsides and our health returns to normal.

What is the disease caused by ticks?

The Borrelia burgdorferi bacteria, a spirochete, is transmitted by tick bite and can cause Lyme disease. The "bull's-eye" rash is a common symptom. Credit: CDC (left), CDC/James Gathany (right) The decline phase is the stage of disease when symptoms begin to abate and the pathogen population begins to decline.

What is the prodromal phase of Lyme disease?

In Lyme disease the prodromal phase corresponds to both the early localized and acute disseminated stages of the disease, which are when the symptoms of a skin rash (erythema migrans) and meningeal irritation (headache) become apparent. The host has a generalized feeling of being unwell.

What are the stages of disease?

There are five stages: incubation period, prodromal period, period of illness, period of decline, and period of convalescence. The symptom threshold is the point at which symptoms are apparent.

How is Lyme disease transmitted?

Lyme disease, caused by the protist Borrelia burgdorferi, is transmitted to humans through the bite of infected ticks. Typical symptoms include fever, headache, and extreme tiredness.

What is the prodromal phase?

The prodromal phase is the stage of the disease process when symptoms first become apparent. These symptoms are typically unspecific to the pathogen and vague; they may include fever, fatigue, and headaches.

How do infections progress?

Differences in severity and duration of the stages in disease progression are often of diagnostic value. After initial invasion of the host, there is an incubation period followed by the prodromal period, the period of illness, the period of decline, and finally the period of convalescence before the infection is completely cleared.

What happens during the convalescence stage of a virus?

During this stage, the infected host develops arthritis, heart rhythm disturbances, memory loss, encephalitis, numbness in the extremities, and severe headaches. The period of decline transitions into the convalescence period, which is the stage of the disease process when symptoms disappear. It is considered a recovery period, when host strength ...

What is the middle of the curve?

The middle of the curve is the period during which primary prevention is most important. If an individual’s health risks are known, their providers can begin working with them on what is preventable. This can be done through education about lifestyle changes for health enhancement (like healthy diet and exercise), engaging individuals in their health, continuously monitoring risk markers for disease progression, and at times, medications to minimize disease development.

Why is shifting the arrow to the left important?

The concept of “shifting the arrow to the left” provides great opportunities for the development of more rational approaches to health care.

What is the natural progression of disease over time?

The natural progression of disease over time is a consequence of inherited susceptibility (genetic inheritance) and exposure to environmental factors, including lifestyle.

How many time periods are there over the trajectory of chronic disease?

There are three time periods over the trajectory of chronic disease. The right portion of the curve is what we hope to avoid; it is when the burden and cost of poor health takes its toll on individuals and society. Early 21 st century health care has made great strides in being able to treat disease once it occurs.

Is intervention more expensive than before?

Our medical technologies are far better than before, but once disease manifests, intervention is often expensive and minimally effective at reversing the underlying problem. For some people, disease development is unavoidable and here personalizing therapy and disease management can substantially improve health outcomes.

Is chronic disease a single factor?

It is becoming more widely understood that chronic disease is often the result of multiple factors rather than one single factor. Different diseases (i.e., cardiovascular disease, metabolic disease, cancers) have different rates of development. In any case, for a long portion of its development, a disease is not clinically apparent ...

What is a person who is infectious but has subclinical disease called?

Such persons who are infectious but have subclinical disease are called carriers. Frequently, carriers are persons with incubating disease or inapparent infection. Persons with measles, hepatitis A, and several other diseases become infectious a few days before the onset of symptoms.

What is the incubation period of a disease?

This stage of subclinical disease, extending from the time of exposure to onset of disease symptoms, is usually called the incubation period for infectious diseases, and the latency period for chronic diseases. During this stage, disease is said to be asymptomatic (no symptoms) or inapparent. This period may be as brief as seconds for hypersensitivity and toxic reactions to as long as decades for certain chronic diseases. Even for a single disease, the characteristic incubation period has a range. For example, the typical incubation period for hepatitis A is as long as 7 weeks. The latency period for leukemia to become evident among survivors of the atomic bomb blast in Hiroshima ranged from 2 to 12 years, peaking at 6–7 years. ( 44) Incubation periods of selected exposures and diseases varying from minutes to decades are displayed in Table 1.7.

What is a timeline in medical terminology?

Description: Timeline shows state of susceptibility, exposure, subclinical disease in which pathologic changes takes place, onset of symptoms, followed by usual time of diagnosis, clinical disease, followed by recovery, disability, or death. Return to text.

For an infectious agent, infectivity refers to the proportion of exposed persons who become infected. Pathogenicity refers to the proportion of infected individuals who develop clinically apparent disease.

What is the transition from subclinical to clinical?

The onset of symptoms marks the transition from subclinical to clinical disease. Most diagnoses are made during the stage of clinical disease. In some people, however, the disease process may never progress to clinically apparent illness.

What is the definition of virulence?

Virulence refers to the proportion of clinically apparent cases that are severe or fatal. Because the spectrum of disease can include asymptomatic and mild cases, the cases of illness diagnosed by clinicians in the community often represent only the tip of the iceberg.

Scarring or inflammation of the tissue makes the lungs unable to expand fully. This makes it hard for the lungs to take in oxygen and release carbon dioxide.

What is the most advanced cognitive achievement a child reaches during this stage?

The most advanced cognitive achievement a child reaches during this stage is object permanence. Object permanence refers to when an infant understands that an object still exists, even when they are not able to see, smell, touch, or hear it.

What motivates a child to continue through the stages of cognitive development?

Equilibration motivates a child to continue through the stages of cognitive development.

Why is object permanence important?

Object permanence is important because it means that the infant has developed the ability to form a mental image, or representation, of an object rather than merely reacting to what they experience in their immediate environment.

What is Piaget's theory of cognitive development?

Piaget’s theory of cognitive development had a significant impact on how people understand childhood development today. Piaget suggests that children go through four distinct stages of cognitive development from birth to adulthood.

How many stages of cognitive development did Piaget describe?

This table and the following sections outline Piaget’s four stages of cognitive development:

How did Piaget develop his theory?

Piaget developed his theories by watching children and making notes about their progress. The core idea of Piaget’s theory is that children develop by acting as “little scientists” who explore and interact with their world to understand people, objects, and concepts.

What is concrete operational stage?

The concrete operational stage is another major turning point in a child’s cognitive development. The child builds on and masters abstract thought. They become less egocentric and more rational.
