Ryanair Initial Practice Exam

Which of the following is a symptom of a communicable disease?

1. Persistent coughing

2. Frequent smiling

3. Increased energy levels

4. Clear skin

The correct answer is: Persistent coughing

Persistent coughing is a common symptom associated with communicable diseases, such as the flu, tuberculosis, or COVID-19. When an individual has a respiratory infection caused by a communicable pathogen, they may exhibit symptoms like coughing as the body attempts to clear the infection from the respiratory tract. In contrast, frequent smiling does not indicate a disease condition, nor do increased energy levels or clear skin. These latter options are generally associated with good health and may not provide any insight related to communicable diseases. Hence, persistent coughing stands out as a notable and relevant symptom linked to such conditions.
