In children,
viral and
bacterial infections can cause diarrhea, vomiting, and
high fevers. Usually the severity of the vomiting is a more
important factor than the child's exact temperature when deciding whether a
visit to the doctor is needed.
Watch the child carefully for
dehydration when he or she has a fever, especially if
your child is also vomiting. Dehydration in babies and small children is very
dangerous.
Babies are more susceptible to dehydration because a larger portion
of their bodies is made of water. Babies also have higher metabolic rates than
adults, so their bodies use more water. However, a baby's kidneys are not as
efficient, and they do not conserve water as well as an adult's kidneys.
Illnesses that cause vomiting or diarrhea can rapidly reduce a baby's fluid
reserves.
If your child has vomiting and a fever, an evaluation may be
needed.
