Cough etiquette is a set of infection control practices designed to minimize the spread of respiratory germs when people cough or sneeze. These guidelines focus on containing the tiny droplets expelled from the mouth and nose that transmit common respiratory illnesses. Practicing cough etiquette is a fundamental component of respiratory hygiene, considered a standard precaution in community and healthcare settings. Adopting these behaviors helps protect the health of those around you by disrupting the chain of infection.
Proper Technique for Covering Coughs and Sneezes
The immediate physical act of covering a cough or sneeze is the first line of defense against germ transmission. The preferred method involves using a disposable tissue to completely cover the mouth and nose. This action intercepts the forceful spray of respiratory secretions, which can travel several feet through the air.
If a tissue is unavailable, the recommended technique is to cough or sneeze into the upper sleeve or the crook of the elbow. This method is often called the “vampire cough” because it directs droplets onto a surface less likely to touch others or common objects.
Avoid covering the cough with a bare hand, as this transfers infectious material directly to the surface most frequently used for touching. A contaminated hand can spread germs to doorknobs, phones, and other people during handshakes. Since respiratory viruses can survive on environmental surfaces, the goal of proper technique is to contain the material on a disposable item or clothing that will not interact with the environment.
Essential Steps for Hand Hygiene and Disposal
Once a cough or sneeze has been contained, the next step is the immediate disposal of the barrier material. Any used tissue must be discarded promptly into a waste receptacle. This ensures the captured germs cannot be transferred to surfaces, as leaving a used tissue exposed risks contaminating the surrounding area.
Following disposal, or after using the elbow method, hand hygiene must be performed without delay. Washing hands with soap and running water is the most effective method, requiring a minimum scrub time of 20 seconds to physically remove microorganisms.
If soap and water are not accessible, an alcohol-based hand sanitizer is an acceptable alternative. The sanitizer should contain at least 60% alcohol to be effective against common respiratory pathogens. Rub the sanitizer over all surfaces of the hands until they are completely dry. Both methods drastically reduce the number of viable germs on the skin, preventing their spread.
Preventing Illness Transmission
Practicing cough etiquette is a public health strategy rooted in understanding how respiratory infections are spread. When a person coughs or sneezes, they expel respiratory droplets containing viruses or bacteria from the nose, mouth, throat, and lungs. These droplets can travel between three to six feet before falling to the ground or settling on surfaces.
The function of cough etiquette is to interrupt this droplet transmission pathway, preventing particles from becoming airborne or directly contacting another person. Containing the expelled material significantly reduces the number of infectious germs introduced into the shared environment. This containment protects vulnerable populations, such as the elderly or those with compromised immune systems, who may be severely affected by respiratory illnesses.
Adherence to these steps collectively reduces the spread of seasonal influenza, the common cold, and other acute respiratory illnesses. When everyone follows proper technique and hand hygiene, the community burden of disease decreases. This makes workplaces, schools, and public transportation safer spaces by ensuring that a single respiratory event does not lead to a cascade of infections.
