Alcohol-based hand rubs may not be suitable for which of the following conditions?

Alcohol-based hand rubs may not be suitable for individuals with alcohol allergies. This is because the primary active ingredient in most hand sanitizers is alcohol, which can trigger allergic reactions in people with sensitivities to this substance. Understanding the potential for allergic responses is critical, especially in healthcare settings where maintaining proper hand hygiene is essential but should not come at the expense of an individual's health.

The other conditions present different considerations. For instance, while dry skin conditions might not be ideal for repeated use of alcohol-based products due to potential aggravation, individuals are still able to use them with caution. Bacterial infections typically require effective hand sanitation methods, and alcohol-based rubs are designed to combat such pathogens. Frequent hand washing is generally encouraged, and alcohol-based hand rubs serve as a supplement when soap and water are not available, rather than a contraindication.
