High temperature or fever is a symptom of a condition, usually an infection. Many people feel much better when the fever is treated, but depending on your physical condition, cause of the fever and age, it may not require a medical treatment.
Some scientists believe that the fever is a body defense mechanism to fight infection. Viruses cannot function on a higher body temperature, so due to fever they should be eliminated. There are several causes of fever that aren’t caused by infections.
Although, fever is treated as harmless, hyperthermia, a cause of heat stroke, some drugs and stroke, can be dangerous. During this condition, the body cannot control its temperature. Children who suffer from fever and have symptoms like: diarrhea, ear pain, coughs and sore throat, require a medical attention.
For example, infant younger than 4 months, with a temperature (rectal) of 100.4 F or above, should be taken to the doctor immediately, because it can be a result of a dangerous infection. If a child has a fever of 104F or above, medical attention is also required!
If your child look very sick, has a seizure, is drowsy or very fussy, has some medical problem or a weakened immune system or have symptoms like: sore throat, rash, earache, headache or stiff neck, you must take him to the doctor immediately! If your child is older than 2 years and fever last longer than 3 days, or your child is less than 2 years old and the fever lasts more than 1 day, take him to the doctors also!
The reason for the fever is linked to the brain. A part of it, called hypothalamus controls body temperature. During the day, it usually varies from 98.6F, which is treated as normal temperature.
