Interruption of transmission of disease is called:

 # Interruption of transmission of disease is called:
A. Disease control 
B. Disease eradication
C. Disease elimination
D. Disability limitation



The correct answer is C. Disease elimination.

Concept of Control
A. Disease control : The term 'disease control' describes (ongoing) operations aimed at reducing incidence, duration, decrease effects of disease, etc. Control activities may focus on primary prevention or secondary prevention. The concept of tertiary prevention is comparatively less relevant to control efforts. In disease control, the disease agent is permitted to persist in the community at a level where it ceases to be a public health problem according to the tolerance level of local population.

B. Disease elimination: Between control and eradication, an intermediate goal has been described, called 'regional elimination'. The term elimination is used to describe interruption of transmission of disease, eg. elimination of measles, polio and diphtheria from large geographic region or areas. Regional elimination is now seen as an important precursor of eradication.

C. Disease eradication: Eradication literally means to 'tear out by roots'. It is the termination of all transmission of infection by extermination of the infectious agent through surveillance and containment. As the name implies, eradication is an absolute process, and not a relative goal. It is an all or none phenomenon.

Most Important Operative Dentistry MCQs With Explanations

1. The following chemically bond to the tooth: A. Composite resin. B. Dental sealants. C. Glass ionomer cement. *** D. All of the above. 2. Compomer restorative materials are: A. Glass ionomer with polymer components B. Resin systems with fluoride containing glasses. *** C. Composite resin for cervical restorations only. Explanation: The composition of compomers is similar to that of a dental composite however it has been modified, making it a polyacid-modified composite. This results in compomers still requiring a bonding system to bond to tooth tissue. Although the name compomer implies that the material possesses a combination of characteristics of both composite and glass ionomers, these materials are essentially polymer-based composites that have been slightly modified to take advantages of the potential fluoride-releasing behavior of glass ionomers. 3. Loose enamel rods at the gingival floor of a class II amalgam cavity should be removed using : A. Straight chisel...
