What is a key component of proper cough etiquette?

Cough etiquette is essential in preventing the spread of respiratory infections. Coughing into a bent elbow is effective because it minimizes the transfer of pathogens to surfaces and avoids direct contact with hands. This action helps contain respiratory droplets that may carry viruses or bacteria, thus protecting both the individual coughing and those nearby.

Using a bent elbow also reduces the risk of contaminating surfaces that might be touched by others, as hands are commonly used for a variety of tasks and may facilitate the transfer of pathogens from one person to another. It is a practical and hygienic method that is widely recommended by health organizations, especially during cold and flu seasons or during public health crises such as pandemics.

Other methods, such as coughing into one's hand or not covering the cough at all, can lead to increased spread of germs, as they do not effectively contain respiratory droplets.
