Ryanair Initial Practice Exam

Which of the following is NOT a sign of a communicable disease?

1. Persistent vomiting

2. Skin rash or spots

3. Temperature increase

4. Confusion of recent onset

The correct answer is: Temperature increase

When assessing signs of communicable diseases, persistent vomiting, skin rashes, and confusion are commonly recognized as potential indicators of various infectious conditions. Each of these symptoms can be associated with infections that can spread from one individual to another. Conversely, an increase in temperature, or fever, is a well-documented response of the body to infection, often signaling that the immune system is actively fighting off pathogens. Fever itself is frequently present in a wide range of communicable diseases, including viral and bacterial infections. The distinction here lies in the context of symptoms; while persistent vomiting, skin rashes, and confusion can arise from a myriad of causes—some of which may be non-communicable—the increase in body temperature is a typical reaction that aligns closely with the body's defense mechanisms against infectious agents. Thus, recognizing an increased body temperature as a common indicator rather than an outlier helps clarify its role in identifying communicable diseases.
