Final answer:
If hands cannot be washed due to a water service interruption, use an alcohol-based hand sanitizer with at least 60% alcohol as an alternative. Hand sanitizers are not as effective when hands are visibly dirty; in such cases, seek an alternative water source for handwashing. Regular handwashing should continue once running water is accessible.
Step-by-step explanation:
If hands cannot be washed during a water service interruption, using an alcohol-based hand sanitizer that contains at least 60% alcohol is recommended. The CDC suggests this as an alternative to handwashing, particularly when soap and water are not readily available. However, it is crucial to note that hand sanitizers do not eliminate all types of pathogens, especially if hands are visibly dirty or greasy. In such scenarios, finding an alternative source of clean water for handwashing is important. When access to running water returns, regular handwashing should resume immediately.
Proper handwashing is essential for preventing the spread of infections, and it is especially important in settings without regular access to clean water. This is because diseases such as typhoid, cholera, and diarrhea, which are spread through unsafe water, have a significant impact on global health. By adhering to proper hand hygiene practices, individuals can reduce the risk of illness and contribute to the wellbeing of their communities.
