What does a subclinical case refer to?

What does a subclinical case refer to?

• A. The host experiences mild symptoms of infection
• B. The host has severe symptoms
• C. There is no infection present
• D. The infection is purely psychological

Answer: (A)

Subclinical infection means the pathogen is present in the host and replicating, but there are no or only very mild symptoms that don’t constitute a full clinical illness. In this context, describing the situation as having mild symptoms best fits the idea that infection exists without a noticeable, typical disease presentation. The other options imply no infection, severe illness, or symptoms that are purely psychological, which do not reflect an infection that is present but not fully clinically apparent.
