Case scenario A 19-year-old male visits his primary care physician with a sore throat, swollen lymph nodes, and extreme fatigue. During the visit, the nurse finds that he has a fever. The patient reports that he is attending his second year of college at a local university. The physician performs a physical examination, which confirms large, swollen, painful lymph nodes. He decides to send the patient to the office laboratory for blood work. He orders a complete blood count (CBC) and viral and bacterial studies. Question: 1. Based on the information obtained thus far, what does the laboratory analysis indicate? Explain your answer.

The patient's symptoms of fever and painful, swollen lymph nodes are caused by what innate immune mechanisms? Explain your answer 3. About 50% of patients with chronic viral infection develop splenomegaly. Based on what you know about the organs of the immune system, why would this condition develop?
