When should someone seek medical care for a fever?

Any child below 3 months of age who has a temperature of 100.4 F (38 C) or greater should be seen by a physician. If a child or adult has a history or diagnosis of cancer, AIDS, or other serious illness, such as heart disease, diabetes, or is taking immunosuppressant drugs, medical care should be sought for a fever.

Otherwise, observe the person with the fever. If he or she appears sick or has symptoms that would suggest a major illness, such as meningitis (headache, stiff neck, confusion, problems staying awake), urinary tract infection (shaking chills, burning with urination), pneumonia (shortness of breath, cough), or any other signs of a serious illness, contact a health-care professional.

Other symptoms that may be indicative of a severe illness include repeated vomiting, severe diarrhea, or skin rashes (that could be a sign of dengue fever, Rocky Mountain spotted fever, scarlet fever, rheumatic fever, strep throat, or chickenpox).

Fever blisters (herpangina) are small blisters that turn into ulcers, usually on the lips, mouth, or tongue; a virus causes fever blisters. When a child contracts this virus for the first time, the symptoms and the fever blisters can be quite severe. If the child is not eating or drinking, contact a child's doctor.

Women who are pregnant should contact a doctor for a fever over 101 F (38 C). A fever during pregnancy that is accompanied by a rash and joint pain could be a sign of an infection that could affect the baby. Some infections, such as cytomegalovirus (CMV), can cause congenital deafness and other problems in the baby.

On the other hand, if the fever accompanies a simple cold or virus, one can treat the fever as described above and be assured that the fever is only a symptom of the illness. This is not to say that someone should ignore a fever. If there are other associated symptoms that are bothersome, contact a doctor.

Some vaccines given in childhood can cause a low-grade fever within a day or two of getting the injection. This fever is usually self-limited and short-lived. If the reaction seems severe or the skin at the injection site is red, hot, and painful, contact the child's doctor.

A low percentage of all children between 18 months to 3 years of age will have a seizure (convulsion) with a high fever. Of those with a history of febrile seizure, some will have another seizure associated with another febrile episode. Febrile seizures, while frightening to the parents, are not associated with long-term nervous-system complications. Children used to be prescribed the antiseizure drug phenobarbital following a febrile seizure as a preventive measure (prophylaxis). This has not been shown to be beneficial and possibly may be harmful, so it is not always recommended.
