Final answer:
A long-term care facility is kept clean primarily to prevent the spread of infections and protect everyone's health within the environment.
Step-by-step explanation:
The main reason a long-term care facility is kept clean is to prevent the spread of infections and ensure a safe environment for residents, staff, and visitors. Cleanliness is paramount in healthcare settings, as it plays a critical role in infection control. Such facilities require rigorous cleaning protocols to remove germs and contaminants that can lead to illness. For example, the comprehensive cleaning of air conditioning systems and the implementation of regular maintenance programs are instrumental in preventing the growth of harmful biofilms. Additionally, in long-term care facilities, it's important to support the daily life routines of residents, including ensuring they have a clean environment to perform activities like eating and maintaining personal hygiene.
