Final answer:
Increased confusion or disorientation can be a possible sign of infection, such as urinary tract infection or meningitis.

Increased confusion or disorientation can be a possible sign of infection. For example, in the case of urinary tract infection (UTI), the infection can spread to the urinary tract and cause symptoms such as confusion or disorientation, along with fever and dysuria (painful urination). Similarly, in the case of meningitis, which is an infection of the tissue surrounding the brain and spinal cord, symptoms can include confusion and drowsiness.
