A fever and symptoms that affect the brain and nervous system may
mean a serious infection is present. Symptoms include:
The
flu, which usually is not serious, can cause a high
fever. You usually will also have body aches, rather than other, more serious,
symptoms.
If a serious infection is present, other symptoms in addition to
fever usually are present or will develop quickly. Any fever with signs of a
serious infection needs to be evaluated immediately by a health
professional.
