The etiology of the flu epidemic of 1918 remains unknown to this day. What does the word "etiology" refer to in this context?
Correct answer
C
Rationale
The term 'etiology' refers to the cause or origin of a disease. In the context of the 1918 flu epidemic, understanding its etiology involves identifying the primary cause behind its occurrence. Pathology deals with the study of diseases, transmission relates to how diseases spread, and mortality rate measures deaths caused by a disease. However, none of these directly address the fundamental cause of the epidemic. Therefore, the correct answer is 'C: Cause.'
