Fever is when a human’s body temperature goes above the normal range of 36–37° Centigrade (98–100° Fahrenheit). It is a common medical sign.
When somebody has a fever, signs and symptoms are linked to what is known as sickness behavior, and may include:
- feeling cold when nobody else does
- lack of appetite
- dehydration — preventable if the person drinks plenty of fluids
- hyperalgesia, or increased sensitivity to pain
- problems concentrating
If the fever is high, there may also be extreme irritability, confusion, delirium, and seizures.
Fevers can be classified according to how long they last, whether or not they come and go, and how high they are.
A fever can be:
- low grade, from 100.5–102.1°F or 38.1–39°C
- moderate, from 102.2–104.0°F or 39.1–40°C
- high, from 104.1–106.0°F to or 40.1-41.1°C
- hyperpyrexia, above 106.0°F or 41.1°C
The height of the temperature may help indicate what type of problem is causing it.
Length of time:
A fever can be;
- acute if it lasts less than 7 days
- sub-acute, if it lasts up to 14 days
- chronic or persistent, if it persists for over 14 days
Fevers that exist for days or weeks with no explanation are called fevers of undetermined origin (FUO).🔥73 Views
