Body temperature can vary from one individual to the next. It also
varies by location on the body and time of day. The below table 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 indicates that the body
temperature is higher than normal. This symptom may be caused
by infection, overdressing or immunisation. Some people may not
experience fever, even when they are ill. These include, but are
not limited to, infants younger than 3 months old, individuals with
compromised immune systems, those taking antibiotics, steroids or
antipyretics (aspirin, ibuprofen, acetaminophen), and in the case of
certain chronic illnesses. Please consult your physician if you feel ill,
even if you do not have fever.
