Practicing precautionary measures to protect the health of the unborn can be compared with wearing seatbelts in cars. Seatbelts were developed to protect people from serious injury in a crash. They can only make a difference if people know about them and use them. There will still be some crashes, but people who are belted in have done what they can to protect themselves. So, by learning about CMV and sharing the information with others, all will have the opportunity to do what they can to protect their future children from the potentially devastating effects of this virus.
