A low white blood cell (WBC) count, known as leukopenia, can indicate various medical conditions. One significant implication of a low WBC count is its relationship with immunodeficiency. When the body has fewer white blood cells, there are fewer immune cells available to respond to infections, making the individual more susceptible to illnesses. Conditions such as bone marrow disorders, certain infections (like HIV), or autoimmune diseases can lead to a low WBC count and, consequently, immunodeficiency.

Additionally, a low WBC count can sometimes be associated with infections, particularly if the body is overwhelmed by a severe infection. The bone marrow might be unable to produce enough white blood cells to meet the demand of fighting off the infection or could be producing fewer cells due to the infection itself.

Therefore, the correct answer indicates that both infection and immunodeficiency could be consequences of low WBC count, making it an important clinical finding that needs further investigation in relation to the patient's health.
