Which term describes a host that experiences mild symptoms of the infection?

• A. Subclinical case
• B. Carrier
• C. Endogenous infection
• D. Exogenous infection

Answer: (A)

Subclinical infection describes an infection that does not produce noticeable symptoms or only minimal ones that don’t amount to a clinical illness. This fits a host who experiences mild symptoms, as the infection is present but not enough to be classified as a full clinical disease. A carrier, by contrast, harbors the pathogen and can transmit it without or with very few symptoms, but the focus is on transmission potential rather than symptom level. Endogenous infection refers to disease arising from within the host’s own flora, and exogenous infection comes from an external source. Thus, subclinical is the best match because it centers on infections with minimal or no noticeable symptoms.
