Is a prodromal period exists for a certain disease it should occur prior to?
The prodromal stage refers to the period after incubation and before the characteristic symptoms of infection occur.

What is the name of the science that deals with when diseases occur and how they are transmitted?
Epidemiology is the study of the determinants, occurrence, and distribution of health and disease in a defined population.
When does disease occur?
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. In response to infection, your immune system springs into action.
What are the three stages of disease development?

During which stage of the disease pattern are there generally clinical signs of illness present?
The prodromal period occurs after the incubation period. During this phase, the pathogen continues to multiply and the host begins to experience general signs and symptoms of illness, which typically result from activation of the immune system, such as fever, pain, soreness, swelling, or inflammation.
What are the 4 types of illness?
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 are the stages of illness?
The illness period is the third of the four major stages of infectious disease. The first is the incubation period followed by prodromal period. After prodromal is the illness period. During the illness stage, symptoms characteristic of a particular disease are recognized.
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 12.2. 1). The incubation period occurs in an acute disease after the initial entry of the pathogen into the host (patient).
What is the science of diseases called?
The study of disease is called pathology.
What is the science of infectious diseases called?
Infectious disease epidemiology (which includes the epidemiology of viruses) is the study of the complex relationships among hosts and infectious agents.
What is it called when a disease is easily transmitted?
A contagious disease is a disease that is readily spread (that is, communicated) by transmission of a pathogen from an infected person to another person. Contagious diseases vary in how readily they are communicated.
What is disease in biology?
In simple terms a disease can be defined as a disorder of structure or function of an organism that is not a direct result of physical injury. The manifestation of disease is a direct consequence of a disruption of function of a biological system at a molecular and cellular level.
How does this disease occur?
Infectious diseases commonly spread through the direct transfer of bacteria, viruses or other germs from one person to another. This can happen when an individual with the bacterium or virus touches, kisses, or coughs or sneezes on someone who isn’t infected.
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 2). The incubation period occurs in an acute disease after the initial entry of the pathogen into the host (patient).

Why do disease outbreaks occur?
Disease outbreaks are usually caused by an infection, transmitted through person-to-person contact, animal-to-person contact, or from the environment or other media. Outbreaks may also occur following exposure to chemicals or to radioactive materials. For example, Minamata disease is caused by exposure to mercury.

What are the stages in disease development?
The five periods of disease (sometimes referred to as stages or phases) include the incubation, prodromal, illness, decline, and convalescence periods (Figure 2).
What are the 3 factors that cause disease?
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.

What stage begins when the more specific signs and symptoms appear?
The incubation stage occurs right after exposure and before symptoms develop. This stage can range from hours for some infections to days, weeks, or even years for other infections. The next stage is prodromal, which involves mild, nonspecific symptoms.

How many illnesses are there?
Jennifer Sherman, press secretary for the House Energy and Commerce Committee, pointed to an estimate published by the University of Michigan Medical School that there are roughly 10,000 diseases afflicting humans, and most of these diseases are considered ‘rare’ or ‘orphan’ diseases.
