B. LEARNING OUTCOMES

By the end of this topic, students should be able to:

1. Define immune responses to viral infections and explain their role in host defense.

2. Describe innate immune mechanisms involved in antiviral defense, including interferons and natural killer (NK) cells.

3. Explain adaptive immune responses to viral infections, including humoral and cell-mediated immunity.

4. Differentiate the roles of antibodies and cytotoxic T lymphocytes in viral clearance.

5. Explain antigen presentation and immune memory in viral infections.

6. Describe mechanisms of viral immune evasion.

7. Relate immune responses to disease outcome, including viral clearance, persistence, and immunopathology.

8. Explain the basis of vaccine-induced immunity against viral infections.

9. Apply knowledge of immune responses to diagnosis, treatment, and prevention of viral diseases.

10. Appreciate host–virus interactions in the context of veterinary, medical, and public health importance.
