Question 3: A previously healthy 8-year-old boy is infected with an upper respiratory tract virus

for the first time. During the first few hours of infection, which one of the following events

occurs?


• a. The adaptive immune system responds rapidly to the virus and keeps the viral infection

under control.

• b. The innate immune system responds rapidly to the viral infection and keeps the viral

infection under control.

• c. Passive immunity mediated by maternal antibodies limits the spread of infection.

• d. B and T lymphocytes recognize the virus and stimulate the innate immune response.

• e. The virus causes malignant transformation of respiratory mucosal epithelial cells, and

the malignant cells are recognized by the adaptive immune system.

• Correct Answer: b. The innate immune system responds rapidly to the viral infection

and keeps the viral infection under control.
