<s>[INST] What is a Fever? [/INST] A fever is a temporary increase in the body’s temperature in response to a disease or virus.

It is an important part of the body’s natural defense against infections. Most bacteria and viruses that cause infections in people thrive at normal body temperature: 37.0°C (98.6°F).

Infants and children develop high fevers with mild viral illnesses and although a fever signals that a battle might be going on in the body, the fever is fighting for, not against that person.

Readings from different measuring sites should not be compared, as the normal body temperature varies by measuring site and time of day. Body temperature will be higher in the evening and lower about one hour before waking up. Source: BIOS MEDICAL . Link: https://biosmedical.com/pages/fever-thermometer-f-a-q.
