Question

Which of the following is usually an endogenous infection?
A)Urinary tract infection.
B)Tetanus.
C)Rabies.
D)Sexually transmitted infection.
E)Influenza.

Accepted Answer

An endogenous infection originates from the patient's own microbiota, such as in the case of a urinary tract infection where bacteria from the bladder or urethra travel up to the kidneys. Tetanus, rabies, sexually transmitted infections, and influenza are generally caused by exogenous pathogens that are acquired from the external environment.
