Question

Which makes viral infections difficult to defend?

A.) the immune system must attack the body’s own cells

B.) viruses are attacked by a nonspecific immune response

C.) viruses live outside of cells

D.) macrophages work slowly

Answer 1

Viral infections are difficult to defend as viruses are attacked by a nonspecific immune response.

Explanation:

• Viral infections often tend to weaken the immune system of the body by turning it incapable of fighting the virus.
• Any external drug administered to fight the virus also leaves an impact on the beneficial cells causing them to cause side effects.
• The response of the immune system to the virus often fails to address the root of the virus and hence, the virus keeps growing stronger.
