Which term would be used to describe a global outbreak of an infectious disease? A - Scottish Highers Human Biology - Question 20 - 2017

To determine the correct terminology for a global outbreak of an infectious disease, we can analyze the definitions of each option:

1. Endemic: This term refers to a disease or condition regularly found among particular people or in a certain area. It does not indicate a widespread outbreak.

2. Sporadic: This implies occasional cases of a disease occurring randomly and not in a consistent pattern. It is not used to describe widespread outbreaks.

3. Epidemic: This term describes an increase in the number of cases of a disease above what is normally expected in a specific area over a specific period of time. While it indicates a regional outbreak, it doesn't imply a global scale.

4. Pandemic: This term is used for a disease that has spread across multiple countries or continents, affecting a large number of people. It is characterized by its global nature.

Based on these definitions, the correct answer to the question is D. Pandemic.
