What is the third stage of infection which begins when more specific signs and symptoms appear?

Illness. The third stage of infection is an illness or clinical disease. This stage includes the time when a person shows apparent symptoms of an infectious disease.

What are the 4 stages of infection?

10.3B: Disease Development
  • Stages of Disease.

What are the 5 stages of infectious disease?

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 are the three phases of infection process?

The different phases in infections include: Infective period. Communicability period.

What are the 6 stages 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. The host is any carrier of an infection or someone at risk of infection.


Which of the following is the third stage of a disease?

Illness. The third stage of infection is an illness or clinical disease. This stage includes the time when a person shows apparent symptoms of an infectious disease.

What stage begins when more specific signs and symptoms?

In medicine, a prodrome is an early sign or symptom (or set of signs and symptoms) that often indicates the onset of a disease before more diagnostically specific signs and symptoms develop.

What are the 3 types of infections?

What causes infections? “Germs” is another word for microorganisms or microbes that cause disease. The three major types of germs we usually hear about are bacteria, viruses, and fungi.

What is the 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 stages of infectious diseases and briefly describe each stage?

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

What is convalescent stage?

Convalescence is the period in which the body recovers from a serious illness, injury or surgery. Changes to your lifestyle may be needed to make sure the body has enough time and rest to allow a complete recovery.

What is acute stage?

Acute: Early onset of symptoms, the maturation phase has not begun. They are generally in the inflammatory or fibroblastic stage of healing, maybe early maturation.

What is acute phase?

any action or change of condition evoked by a stimulus. acute phase response a group of physiologic processes occurring soon after the onset of infection, trauma, inflammatory processes, and some malignant conditions.

What does it mean by acute phase?

A group of physiologic changes that occur shortly after the onset of an infection or other inflammatory process and include an increase in the blood level of various proteins, especially C-reactive protein, fever, and other metabolic changes.

What is secondary infection?

A secondary infection is an infection that occurs during or after treatment for another infection. It may be caused by the first treatment or by changes in the immune system. Two examples of a secondary infection are: A vaginal yeast infection after taking antibiotics to treat an infection caused by bacteria.

What is primary infection?

Definition of primary infection

: the initial infection of a host by a pathogen that has completed a resting or dormant period.

What are the 4 types of diseases with examples?

There are four main types of disease: infectious diseases, deficiency diseases, hereditary diseases (including both genetic diseases and non-genetic hereditary diseases), and physiological diseases. Diseases can also be classified in other ways, such as communicable versus non-communicable diseases.

What is the prodromal stage?

The term "prodrome " refers to the early stage and symptoms of any condition. Here, a person might notice changes in the way they feel, think, or behave. However, they won't experience symptoms such as disorganized thought or behavior, hallucinations, or delusions.

What is the final stage of the infectious process?

– As the host immune system and/or treatments effectively reduce the number of pathogens, symptoms decrease (also called the convalescence stage). – Ultimately, symptoms disappear and the individual returns to health.

What is stage of susceptibility?

Susceptibility: The state of being susceptible (easily affected / infected). A susceptible person does not possess sufficient resistance against a particular pathogen to prevent contracting that infection or disease when exposed to the pathogen.

What are 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 happens during incubation period?

An incubation period is the time between infection or contact with the agent and the onset of symptoms or signs of infection.

What causes an acute phase reaction?

The acute phase response (APR) is a prominent systemic reaction of the organism to local or systemic disturbances in its homeostasis caused by infection, tissue injury, trauma or surgery, neoplastic growth or immunological disorders (Gordon and Koy, 1985; Gruys et al., 1999).

How long is acute phase?

Care of Acute Athletic Injuries

The care of acute (and recurring acute) injuries is often divided into 3 stages with general time frames: acute (0–4 days), subacute (5–14 days), and postacute (after 14 days).

Which stage of infection is occurring when the immune and inflammatory responses are triggered?

Platelet interactions with inflammatory cells may mediate pro-inflammatory outcomes. The acute phase response (APR) is the earliest response to infection or injury, and some studies have indicated that platelets induce the APR [77].
