A fever, or an elevated body temperature, is usually a symptom of infection and not usually a problem of itself. It is one of the ways that we fight infection. If the fever is not causing a problem, you do not have to treat it, though you will often feel a lot better if the fever is treated. A fever should prompt a parent to watch for a source of infection. Viral infections do not have specific treatments. If the fever is high or prolonged despite home therapy, then a visit to your family doctor is advised. Children under 3 months of age, anyone on chemotherapy, anyone with a serious ongoing disease, and those who have had recent surgery should seek medical advice about all fevers.

When taking a temperature you must have the right equipment. You cannot depend on the feel of a forehead with your hand to determine someone’s temperature accurately, You have to obtain either an electronic or glass thermometer. Temperatures are best taken rectally or orally. You should take a look at the thermometer before use and note how you have to rotate the glass to see the mercury or alcohol.The oral temperature may be lower than the rectal temperature because the mouth is cooled by breathing. Be sure you shake the glass thermometer down below 37°C or 99°F before using it.

N.B

AN ORAL TEMPERATURE may be used in older children or adults.

Oral temperatures may be falsely high or low depending on recent hot or cold drinks.

Wait about 10 minutes after drinking to take an oral temperature.

A RECTAL TEMPERATURE is more accurate and should be performed if possible.

This is important in young children who may not cooperate for an oral temperature or may bite a glass thermometer. Taking a rectal temperature does not hurt the child.

Temperature Orally up to 37.5°C (99.5°F) 37.5 - 39.0°C over 39.0°C (taken by mouth) 99.5 - 102°F over 102°F

Temperature Rectally up to 38.0°C (100.4°F) 38.0 - 39.5°C over 39.5°C (taken by rectum) 100.4 - 103°F over 103°F

Keep in mind that body temperature may rise with exercise, with overdressing, after a hot bath, or as a result of very hot weather. Be sure to recheck a temperature you are unsure of in 30 to 60 minutes.
