What are all disease stages?

Definition/Introduction. The natural history of a disease classifies into five stages: underlying, susceptible, subclinical, clinical, and recovery/disability/death.

What are the 5 stages of disease?

The five periods of disease (sometimes referred to as stages or phases) include the incubation, prodromal, illness, decline, and convalescence periods (Figure 12.2. 1). The incubation period occurs in an acute disease after the initial entry of the pathogen into the host (patient).

What are the 4 periods of disease?

When a susceptible host acquires a pathogen, the infection typically progresses through four main stages: incubation, prodromal stage, illness, and convalescence. These stages are of varying duration, depending on the type of pathogen.

What are the 4 categories of disease?

There are four main types of disease: infectious diseases, deficiency diseases, hereditary diseases (including both genetic 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 life cycle of a disease?

All pathogens go through a lifecycle, which takes the organism from reproducing adult to reproducing adult. This cycle includes phases of growth, consolidation, change of structure, multiplication/reproduction, spread, and infection of a new host.

What is the first stage of illness?

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.

What is illness or clinical stage?

During the illness stage, symptoms characteristic of a particular disease are recognized. It is also at this stage that the infectious disease is highly communicable. When the patient overcomes the disease, the ensuing stage is the convalescent period. Also called: illness stage.

What is the early stage of an illness?

Prodromal Stage

A person also begins to show signs of illness, but the symptoms are mild and not very specific or diagnostic. Prodromal symptoms vary based on the type of infectious disease but generally indicate early immune activation and include malaise and fever.

Fifth (erythema infectiosum) and sixth (roseola infantum) diseases are common rash illnesses of childhood that have long been recognized in clinical medicine. The discovery of the viruses that cause these illnesses has revealed relationships with other syndromes.

What are the stages of a virus?

The life cycle of virus. The virus life cycle could be divided into six steps: attachment, penetration, uncoating, gene expression and replication, assembly, and release. The viral capsid (blue) and genome (brown) are schematically drawn for the purpose of explanation. The nucleus is omitted for clarity.

What are the 4 levels of infected?

The host then goes through different developmental stages depending on how long they've been infected: runner, stalker, clicker, and bloater or shambler; each stage more dangerous than the last.

What are the 5 stages of pathogenesis?

The stages of pathogenesis include exposure, adhesion, invasion, infection, and transmission.

What is the end stage of illness?

A terminal illness is an illness or condition which cannot be cured and is likely to lead to someone's death. It's sometimes called a life-limiting illness. On this page, we answer questions that you might have about terminal illness.

What's the deadliest virus?

Using the “case fatality rate” metric to determine what virus is the deadliest, rabies would likely come out on top. That's because, if an infection becomes symptomatic, rabies is fatal to humans in more than 99 percent of cases. Globally, approximately 59,000 people die from rabies every year.
