What is a common symptom of a respiratory infection?

• A. Strong-smelling urine
• B. Loss of appetite
• C. Coughing and sneezing
• D. Abdominal cramping

Answer: (C)

Coughing and sneezing are common symptoms associated with respiratory infections because these actions are part of the body's natural response to irritation in the respiratory tract. When the respiratory system is infected, whether due to a virus or bacteria, the body attempts to clear the pathogens and mucus buildup, which can lead to coughing as an effort to expel irritants. Sneezing occurs as a reflex to help rid the nasal passages of harmful microorganisms, allergens, or irritants. In the context of respiratory infections, symptoms such as coughing and sneezing help to transmit potential pathogens to others, which explains why they are often predominant during such infections. Other symptoms might be present as well, but coughing and sneezing are definitive indicators of respiratory issues.
