Question 1
A 6-month-old male is exposed to respiratory syncytial virus (RSV) for the first time and develops signs and symptoms of infection. Which of the following will be most beneficial to clear his infection?- Apoptosis of virally infected cells by T cytotoxic cells
- Antibiotic therapy to halt viral replication
- Lysis of infected cells via the classical complement pathway
- T helper (Th) cell–induced necrosis of virally infected cells
- Generation of antibodies to neutralize free virus
Clearance of active viral infections occurs through the destruction of infected cells. The primary agents are cytotoxic T cells. Because this is the initial exposure, antibody levels against the virus have not had time to reach effective levels.
