The disease which lasts for only a short period of time is called Acute Disease. For example: Influenza (Flu), Common cold, etc. For example: TB, Cancer, etc.

What is an agent of infection?

Infectious diseases are caused by diverse living agents that replicate in their hosts. The agents that cause disease fall into five groups: viruses, bacteria, fungi, protozoa, and helminths (worms).

What are the types of infection?

Bacterial infections

  • strep throat.
  • bacterial urinary tract infections (UTIs), often caused by coliform bacteria.
  • bacterial food poisoning, often caused by E. coli, Salmonella, or Shigella.
  • bacterial cellulitis, such as due to Staphylococcus aureus (MRSA)
  • bacterial vaginosis.
  • gonorrhea.
  • chlamydia.
  • syphilis.

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).

What is the last stage of infection?

Convalescence. The final stage of infection is known as convalescence. During this stage, symptoms resolve, and a person can return to their normal functions. Depending on the severity of the infection, some people may have permanent damage even after the infection resolves.

What are the three stages of disease?

viral latency: A form of viral dormancy in which the virus does not replicate at all.

  • Stages of Disease.
  • STAGE 1: INCUBATION PERIOD.
  • STAGE 2: PRODROMAL PERIOD.
  • STAGE 3: ACUTE PERIOD.
  • STAGE 4: CONVALESCENCE PERIOD.

Why is it important to know the stages of infection?

Knowing the incubation period of an infectious disease—the time from exposure to the causative agent to when symptoms first appear—can provide important information during an outbreak, including when infected individuals will be symptomatic and most likely to spread the disease.

What is the infection process?

The Infectious Disease Process. [last update The infectious disease process includes the following components: (1) agent (2) reservoir (3) portals of entry and exit (4) mode of transmission (5) immunity. Types of agents range from the submicroscopic to the large parasites.

What is the clinical stage of a disease?

Medical Definition of Clinical disease Clinical disease: A disease that has recognizable clinical signs and symptoms, as distinct from a subclinical illness, which lacks detectable signs and symptoms. Diabetes, for example, can be a subclinical disease for some years before becoming a clinical disease.

What is the incubation stage of infection?

Incubation period: In medicine, the time from the moment of exposure to an infectious agent until signs and symptoms of the disease appear. For example, the incubation period of chickenpox is 14-16 days. In biology, the incubation period is the time needed for any particular process of development to take place.

How do viruses make us ill?

Viruses make us sick by killing cells or disrupting cell function. Our bodies often respond with fever (heat inactivates many viruses), the secretion of a chemical called interferon (which blocks viruses from reproducing), or by marshaling the immune system’s antibodies and other cells to target the invader.

How does a disease start?

Infection occurs when viruses, bacteria, or other microbes enter your body and begin to multiply. Disease, which typically happens in a small proportion of infected people, occurs when the cells in your body are damaged as a result of infection, and signs and symptoms of an illness appear.

What is the iceberg concept of disease?

The study of the “iceberg phenomenon of a disease“ tells of the progress (pathogenesis and spread) of a disease from its sub-clinical stages to apparent disease state. The tip of the iceberg represents what the clinicians see and submerged is the part explored and made visible by the epidemiologists.

Who invented the iceberg theory?

writer Ernest Hemingway

What is the phenomenon of disease infection?

An infection is the invasion of an organism’s body tissues by disease-causing agents, their multiplication, and the reaction of host tissues to the infectious agents and the toxins they produce.

What is the clinical iceberg in health and social care?

Last’s concept of the “clinical iceberg” (Last:1963) describes the presence of a large burden of undetected disease in the community – perhaps up to 94% of all disease.
