What does eradication mean in medical terms?
Eradication: Permanent reduction to zero of the worldwide incidence of infection caused by a specific agent as a result of deliberate efforts; intervention measures are no longer needed.
What diseases are eliminated?
To date, the World Health Organization (WHO) has declared only 2 diseases officially eradicated: smallpox caused by variola virus (VARV) and rinderpest caused by the rinderpest virus (RPV).
What diseases no longer exist?

- Smallpox.
- Rinderpest.
- Poliomyelitis (polio)
- Dracunculiasis.
- Yaws.
- Malaria.
- Hookworm.
- Lymphatic filariasis.
Is elimination the same as eradication?
Eradication refers to the reduction to zero (or a very low defined target rate) of new cases in a defined geographical area. C. Elimination refers to the complete and permanent worldwide reduction to zero new cases of the disease through deliberate efforts.
Does polio still exist?
Wild poliovirus has been eradicated in all continents except Asia, and as of 2020, Afghanistan and Pakistan are the only two countries where the disease is still classified as endemic.
How are diseases controlled?
The infectious diseases may be prevented in one of two general ways: (1) by preventing contact, and therefore transmission of infection, between the susceptible host and the source of infection and (2) by rendering the host unsusceptible, either by selective breeding or by induction of an effective artificial immunity.
How does epidemiology help in controlling diseases?
Epidemiology identifies the distribution of diseases, factors underlying their source and cause, and methods for their control; this requires an understanding of how political, social and scientific factors intersect to exacerbate disease risk, which makes epidemiology a unique science.
What are the 5 main objectives of epidemiology?
In the mid-1980s, five major tasks of epidemiology in public health practice were identified: public health surveillance, field investigation, analytic studies, evaluation, and linkages.
Is an epidemiologist a doctor?
Are epidemiologists considered medical doctors? No. While epidemiologists study and investigate the causes and sources of diseases in much the same way as medical doctors, they’re not considered actual physicians. Perhaps the biggest reason why is treatment.
What is the epidemiological triangle?
The Epidemiologic Triangle, sometimes referred to as the Epidemiologic Triad, is a tool that scientists use for addressing the three components that contribute to the spread of disease: an external agent, a susceptible host and an environment that brings the agent and host together.
What is the best definition for the epidemiological triangle?
A number of models of disease causation have been proposed. Among the simplest of these is the epidemiologic triad or triangle, the traditional model for infectious disease. The triad consists of an external agent, a susceptible host, and an environment that brings the host and agent together.
What are the three components of the disease triangle?
These three elements, pathogen, host, and environmental conditions, make up the disease triangle. The disease triangle is a concept that illustrates the importance of all three elements—just as there are three sides to a triangle, there are three critical factors necessary for disease to develop.
What are the three vertices of the epidemiological triangle?
coli) in describing the three vertices (corners) of the Epidemiologic Triangle. Those vertices are “agent,” “host,” and “environment.” After this in-class introduction, students will gather information about chickenpox and report back to the class on what they have learned.
What are the 3 main elements of descriptive epidemiology?
Descriptive epidemiology covers time, place, and person. Compiling and analyzing data by time, place, and person is desirable for several reasons.
What is the meaning of epidemiological?
By definition, epidemiology is the study (scientific, systematic, and data-driven) of the distribution (frequency, pattern) and determinants (causes, risk factors) of health-related states and events (not just diseases) in specified populations (neighborhood, school, city, state, country, global).
What are the stages phases 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 is the most common means of transmission of infectious diseases?
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 is the infectious disease 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.
How are infectious diseases classified?
The agents of infection can be divided into different groups on the basis of their size, biochemical characteristics, or manner in which they interact with the human host. The groups of organisms that cause infectious diseases are categorized as bacteria, viruses, fungi, and parasites.
What are the 5 major types of infectious agents?
There are five major types of infectious agents: bacteria, viruses, fungi, protozoa, and helminths. In addition, a new class of infectious agents, the prions, has recently been recognized.
What are Infectious Diseases examples?
Infectious diseases are diseases caused by living organisms like viruses and bacteria. They can be passed from person to person through body secretions, insects or other means. Examples are SARS, influenza, the common cold, tuberculosis (TB), Hepatitis A and B.
