Everyone should follow the rules of respiratory etiquette to prevent the spread of all types of respiratory infections at the community level. Which of the following does not contribute to the prevention of the spread of all respiratory infections?

Correct option is B

Answer: (b) Living in a poorly ventilated room
Explanation: Good respiratory etiquette is essential for preventing the spread of respiratory infections such as colds, flu, and COVID-19. Measures that contribute to infection control include:
· (a) Washing hands after coming into contact with secretions → Helps prevent the transmission of pathogens through contaminated hands.
· (c) Covering nose and mouth when sneezing and coughing → Reduces airborne transmission of respiratory droplets.
· (d) Using a tissue to collect respiratory secretions → Prevents the spread of infectious droplets to surfaces and other people.
(b) Living in a poorly ventilated room does not contribute to prevention and, in fact, increases the risk of infection by allowing respiratory pathogens to accumulate in the air. Proper ventilation is crucial in reducing the concentration of airborne pathogens.
Thus, the correct answer is living in a poorly ventilated room as it does not help prevent the spread of respiratory infections.
