I found this hand sanitizer dispenser on the way out of a McDonald's bathroom on Huntington Road. This is an example of public health because it makes access to sanitation easy and available to the public in a convenient and well-placed area. I chose this example because of how bad flu season was this year; if every store, restaurant, and business had invested in these sanitizers to place on their way out the door instead of simply coming out of the bathroom, the spread of influenza could have been minimized. It is important that others consider this an aspect of public health because it only functions as one if it is being used; the dispenser itself does nothing to prevent the spread of disease, but rather the citizens who value the well-being of themselves and others and use this free, accessible hand sanitizer for its intended purpose are the ones who make this a truly effective part of public health.
