Understand the question: The problem is asking which statement about influenza is NOT true. This means we need to evaluate each statement and identify the one that is incorrect.
Review the characteristics of influenza: Influenza is caused by the influenza virus, which is an RNA virus, not a DNA virus. This is a key fact to keep in mind as we analyze the statements.
Analyze the first statement: 'Influenza can be prevented by vaccination.' This is true because vaccines, such as the flu shot, are developed annually to help prevent influenza infections.
Analyze the second statement: 'Influenza primarily affects the respiratory system.' This is true because influenza commonly infects the nose, throat, and lungs, which are part of the respiratory system.
Analyze the third statement: 'Influenza is caused by a DNA virus.' This is false because influenza is caused by an RNA virus, not a DNA virus. Therefore, this is the correct answer to the question.
