What is a portal of entry? Provide an example.

A portal of entry is the route a pathogen uses to get into a new person. It can be through mucous membranes (like the nose, mouth, or eyes), through non‑intact skin, or via invasive devices such as catheters. For example, bacteria on contaminated hands can enter the body when they touch the eyes or mucous membranes, or when a catheter provides a pathway through the skin. This is why procedures that break the body's barriers—hand hygiene, aseptic technique during catheter care, and protecting mucous membranes—are crucial to preventing infection. The other descriptions correspond to other concepts: an exit route from the reservoir, environmental neutralization of pathogens, and the reservoir where pathogens reside.
