Final answer:
Symptoms B) Rash of itchy red spots, fever, fatigue are indicative of chickenpox, which is caused by the varicella-zoster virus and characterized by a pustular rash mainly on the trunk.
Step-by-step explanation:
The set of signs and symptoms that seems to indicate that the patient has chickenpox is B) Rash of itchy red spots, fever, fatigue. Chickenpox is a common childhood disease caused by the varicella-zoster virus, which presents initially with cold-like symptoms including fever and chills. A few days after the fever, a characteristic pustular rash appears, starting on the face and then spreading to the trunk and extremities, but is mostly concentrated on the trunk region. Over time, these lesions burst and form crusty scabs.
Another key detail is that individuals with chickenpox are infectious a couple of days before the rash outbreak and remain so until all the lesions have scabbed over. While treatment for chickenpox infections in children is generally not required, there are vaccines available for both chickenpox prevention and for reducing the likelihood of shingles, which is caused by reactivation of the varicella-zoster virus in adults who had chickenpox in their youth.
