Which of the following practices is recommended in controlling infection risks?

Vaccinating healthcare workers is a highly recommended practice in controlling infection risks. Vaccination helps protect not only the healthcare workers themselves but also their patients and the broader community from vaccine-preventable diseases. When healthcare workers are immunized, they are less likely to transmit infections, especially in high-risk environments such as hospitals and clinics where vulnerable populations are present. Vaccines play a critical role in maintaining the health of healthcare professionals, ensuring a safer environment for both providers and the individuals they care for.

The other practices either do not effectively contribute to infection control or could lead to increased risks. For instance, applying hand lotion before sanitizing can lead to reduced efficacy of hand sanitizers, which are designed to kill pathogens. Wearing additional layers of clothing may not necessarily reduce infection risk and could even contribute to discomfort or inhibit proper hygiene practices. Using hand sanitizer sparingly does not align with infection control guidelines, as frequent use of hand sanitizer is essential in maintaining hand hygiene, especially in healthcare settings.
