What does an effective cough etiquette aim to do?

An effective cough etiquette is primarily designed to prevent the spread of respiratory infections. This practice involves actions such as covering the mouth and nose with a tissue or elbow when coughing or sneezing, disposing of tissues properly, and washing hands afterward. By adopting these measures, individuals can significantly reduce the likelihood of infectious droplets being released into the air, which helps protect both the individual and those around them from becoming ill.

This is essential in healthcare settings, where the risk of infection transmission can be particularly high. Maintaining respiratory hygiene not only safeguards personal health but also upholds a broader public health standard by minimizing the potential for outbreaks.

The other choices do not align with the goal of cough etiquette. For example, encouraging coughing openly contradicts the principle of controlling the spread of germs, while increasing airborne disease transmission directly opposes the intent of cough etiquette. Thus, the emphasis on prevention is what makes the first choice the correct answer.
