Keeping the wound clean and covered is vital to prevent infection because it minimizes exposure to pathogens that can enter the wound. A clean environment helps limit the introduction of bacteria and other contaminants, which are common sources of infection. Covering the wound with a sterile dressing not only protects it from external dirt and microorganisms but also helps to retain moisture, which is important for the healing process.

In contrast, applying ointment before cleaning can potentially trap dirt or bacteria under the ointment if the wound is not properly cleaned first. A tight bandage around the wound can restrict blood flow and may lead to further complications, such as tissue damage. Exposing the wound to air can also increase the risk of infection, as it allows for easier access for airborne pathogens. Therefore, ensuring that the wound remains both clean and adequately covered is the best approach to infection prevention.
