Which of the following is NOT a common type of HAI?

Seasonal flu infections are primarily caused by influenza viruses and are classified as viral respiratory infections rather than healthcare associated infections (HAIs). HAIs typically occur in healthcare settings such as hospitals or long-term care facilities and are often the result of a medical intervention, like surgery or catheter placement.

In contrast, surgical site infections, bloodstream infections, and urinary tract infections are all common types of HAIs that can arise due to factors such as surgical procedures, the use of intravenous lines, or catheters, respectively. These infections are associated with the healthcare environment and the procedures that take place within it, making them distinct from seasonal flu, which can affect individuals in both healthcare and community settings without necessarily being linked to specific medical care.
