4. The difference between an infection and an infectious disease is that an:
|
A. |
infection never causes an infectious disease. |

B. |
infection comes after the infectious disease has already started. |

D. |
infectious disease and an infection can never involve the same microbe. |
ANS: C
|
Feedback |
|
|
A |
Some infections can lead to disease. |
|
B |
An infection comes first. |
|
C |
An infection does not always indicate disease, but disease (damage to the body) seldom results without infection (the exception is toxigenic diseases). |
|
D |
This is not true. |
