Question

Match List - I with List - II.

List - I (Term)	List - II (Meaning)
A. Epidemic B. Endemic C. Pandemic D. Zoonoses	I. A disease when it has continued transmission in a defined population at relatively low level II. Disease with unexpectedly high frequency across nations III. Infections that are transmitted between animals and humans IV. Occurrence of a disease in a defined population or area with a frequency higher than normal

Choose the correct answer from the options given below:

• A. A-I, B-II, C-III, D-IV
• B. A-IV, B-III, C-II, D-I
• C. A-IV, B-I, C-II, D-III
• D. A-III, B-II, C-I, D-IV

Hint:

Endemic means constant presence of disease, while Pandemic refers to worldwide spread of disease.

Answer 1

The Correct Option is C

Concept: Important epidemiological terms describe the occurrence and spread of diseases in populations.
• Epidemic -- sudden increase of disease above normal level in a community.
• Endemic -- continuous presence of a disease at a usual level in a region.
• Pandemic -- epidemic spreading across countries or continents.
• Zoonoses -- diseases transmitted between animals and humans.

Step 1: Match Epidemic.
An epidemic is the occurrence of disease cases in a population at a frequency higher than expected. Hence, \[ A \rightarrow IV \]

Step 2: Match Endemic.
Endemic disease remains continuously present in a population at a relatively low and stable level. Hence, \[ B \rightarrow I \]

Step 3: Match Pandemic.
A pandemic is a disease outbreak occurring across countries or continents with very high frequency. Hence, \[ C \rightarrow II \]

Step 4: Match Zoonoses.
Zoonoses are infections transmitted between animals and humans. Hence, \[ D \rightarrow III \]

Step 5: Select the correct option.
Thus, the correct matching is: \[ A-IV,\; B-I,\; C-II,\; D-III \] Therefore, the correct answer is: \[ \boxed{(C)\ A-IV,\; B-I,\; C-II,\; D-III} \]
