A fever occurs when the body's core temperature is elevated above its normal range due to a medical condition or illness. Fevers are commonly caused by a viral or bacterial infection, where the body's natural response is to increase its temperature to kill the microbes.
A fever can cause an individual to feel unwell and bring with it a host of other symptoms. Although mild fevers usually go away on their own after a few days, some medications can help lower fevers sooner or alleviate uncomfortable symptoms. Drinking plenty of fluids, getting enough rest and wearing lightweight clothing may also help speed up recovery.1’Fever.’ Mayo Clinic, Mayo Foundation for Medical Education and Research, 13 May 2020, www.mayoclinic.org/diseases-conditions/fever/symptoms-causes/syc-20352759
Higher Than Normal Body Temperature
The hallmark symptom of fever is a high body temperature. The average normal body temperature is 98.6 degrees, however, this can vary between individuals. A temperature within the range of 97 to 99 degrees is generally considered normal. Typically, adults don't need to be concerned unless their temperature reaches 103 degrees or higher. However, when a baby or child has a higher-than-normal temperature, it may be a sign of a more severe infection.
Different types of thermometers can be used to take a person's temperature, such as oral, rectal, ear and forehead thermometers.1’Fever.’ Mayo Clinic, Mayo Foundation for Medical Education and Research, 13 May 2020, www.mayoclinic.org/diseases-conditions/fever/symptoms-causes/syc-20352759
