To prevent the spread of microbes, what is a key practice?

Washing your hands is recognized as a key practice in preventing the spread of microbes. Hand hygiene is fundamental in healthcare settings and everyday life because it effectively removes dirt, viruses, and bacteria from the hands. Proper handwashing techniques involve using soap and water to scrub all surfaces of the hands for at least 20 seconds or using an alcohol-based hand sanitizer when soap and water are not available. This action significantly reduces the likelihood of transmitting infections, especially in environments where individuals are at greater risk, such as hospitals or nursing homes.

Other options, while they may contribute to cleanliness or comfort in different contexts, do not directly address the core issue of microbial transmission. Wearing shoes indoors can help maintain cleanliness, but it does not actively eliminate germs. Limiting food in patient areas may help reduce the risk of pest infestations and maintain general hygiene, but it does not address hand hygiene. Using air fresheners can improve the smell of a space but does nothing to eliminate germs. Therefore, handwashing stands out as the most effective preventive measure against the spread of microbes.
