Question

Which statement correctly describes why children are more susceptible to infectious diseases?
A) Children inherit this susceptibility from their parents.
B) A child's immune system is not fully developed and continues to mature throughout childhood.
C) Children are not as clean as adults.
D) Children are not more susceptible to infectious diseases.

Accepted Answer

Babies are born with partially developed immune systems. The immune system is responsible for helping fight disease throughout a person's lifetime. A child's immune system continues to mature throughout childhood. For this reason, children are often more vulnerable to infectious diseases, which result from being infected by a microorganism such as a bacterium or virus.
