Final answer:
Not washing hands after touching a doorknob exposes an individual to microbes on fomites, highlighting the importance of handwashing to prevent illness.
Step-by-step explanation:
Not allowing an individual to wash their hands after touching a doorknob is termed exposure to fomites. Fomites are inanimate objects, like doorknobs, that can harbor microbes and aid in the transmission of diseases. It is critical to practice good hygiene, such as handwashing, to prevent the spread of contagious illnesses.
In a healthcare setting, strict protocols, including rigorous handwashing, are essential to prevent surface and equipment contamination as highlighted by Figure 13.27 illustrating the CDC handwashing steps.
