The body temperature can vary with the individual. It
also varies at different parts of the body and different
time of the day. The following table1 shows the
statistical normal ranges from different sites. Please
keep in mind that temperatures measured from different
sites, even at the same time, should not be directly
compared.
Fever means that the body temperature is higher than
normal. This symptom may be potentially caused by
infection, overdressing or immunization. But some
people may not undergo fever even when they are
ill. These include, but are not limited to, infants not
more than 3 months old, persons with compromised
immune systems, persons taking antibiotics, steroids
or antipyretics (aspirin, ibuprofen, acetaminophen), or
persons with some chronic illnesses. Please consult
your physician when you feel ill even if there is no fever.
