The first thing that came to mind is the use of antibacterial hand soap and hand sanitizer. We increase its use when we want to decrease bacterial exposure and transmission such as when there is a sickness in the home or there is a newborn baby. We also regularly bathe and shower which decreases the microbes that cause body odor. We brush and floss our teeth to decrease the microbes that cause smelly breath, cavities, and mouth diseases. Some individuals add bleach to their dish soap to kill the bacteria. The use of face masks decrease exposure to airborne microbes. Some parents will restrict their children to indoor play to avoid bacterial exposure.
