Strict infection-control measures must be applied:

Strict infection-control measures are crucial in the healthcare environment to protect both patients and healthcare workers from the transmission of infections. Implementing these measures for every patient ensures a comprehensive approach to infection control, minimizing the risk of transmission regardless of a patient's known health status or signs of illness.

Using strict infection-control practices universally helps to account for the fact that not all infections may present with symptoms, and some individuals may be carriers of infectious diseases without showing obvious signs. By applying these measures to every patient, healthcare providers create a safer environment and adhere to best practices in infection control. This proactive approach is fundamental in preventing outbreaks and safeguarding public health.

In contrast, implementing measures only for specific groups, such as those with known communicable diseases or appearing ill, leaves gaps in protection that can result in the spread of infections.
