Why exercise good hygiene practices?
The objective of better hygiene practices is to minimize the potential for disease to spread. Such practices include limiting the dissemination of germs outgoing from infected sources, and impeding the potential for the reception of infected agents. That means that a sick person must try to contain coughs and sneezes, for example, while a healthy person needs to be mindful about breathing in infected particles or touching infected surfaces. This is easier said than done, yet there are measures a sick person can take as well as practices a healthy person can observe to lower these various means of disease transmission. And, this applies to all colds and all flu viruses.
