Final answer:
Medical procedures can cause the portal of entry in the chain of infection. This occurs when pathogens enter the body through routes like incisions or wounds during surgeries or injections.
Step-by-step explanation:
Medical procedures can cause the portal of entry part of the chain of infection. The portal of entry is the route through which a pathogen enters the body. During medical procedures, such as surgeries or injections, there is a potential for pathogens to enter the body through incisions, wounds, or needle punctures.
For example, if a surgical site is not properly cleaned and sterilized, bacteria can enter the body through the incision, leading to an infection.
Therefore, it is important for healthcare providers to follow strict infection control measures to minimize the risk of pathogen entry during medical procedures.
