What is the best way to measure body temperature?

The best way to measure body temperature is using a thermometer inserted orally, rectally, axillary (under the arm), or by using a special instrument commonly sold in stores that is inserted in the ear and measures the temperature of the eardrum.

Can a fever be treated at home?

If your fever is mild (less than 101°F), then no medical treatment is required. Simply make sure that you drink plenty of fluids (not alcohol) – and get plenty of rest.

For higher temperatures, there are many effective ways to getting your fever under control. The most common way includes medications such as aspirin, acetaminophen and ibuprofen.

If you have a child under age 17 who has a fever, DO NOT give the child aspirin. Aspirin in children may cause Reye's syndrome, a sometime fatal illness. Taking a lukewarm bath (around 98°F) may also help bring the body's temperature down.
