What is Fever?
Fever is what we call it when your child's body temperature is more than 38
C. It is a natural part of a body
trying to fight infection and will not cause any damage to your child. The infection might be caused by a
virus, bacteria, or even a parasite or fungus. The most common infections are caused by viruses and cannot
be treated by antibiotics. The best approach to fever is to avoid infection with good hand washing and
covering your mouth when you cough or sneeze.
Taking your child's temperature:
Normal body temperature is a little bit different from person to person. It also changes a little bit, through
the day. The following chart shows the conversion for body temperatures:

There are many ways to check your child's temperature. Newborns and children < 2 years old should have
their temperatures checked rectally (through the bum), which gives the best reading. In older children,
temperature can also be checked in the ear, in the armpit, under the tongue and on the temples, but these
are less accurate.
