Fever occurs to aid the immune system when it has to fight against pathogens such as viruses and bacteria. The increased body temperature speeds up the metabolism and prevents pathogens from multiplying. Babies and toddlers get frequent fever than older children and adults.
Babies and children often have a fever and body temperature varies generally stronger than in adults. But even if the fever may frighten parents: High fever in children does not necessarily mean that the child is seriously ill.

Fever may many symptoms cause:
The temperature center in the brain controls the heat control the human body. This center is located in the region of the so-called hypothalamus, a part of the diencephalon. Fever occurs when the target value of the body temperature is adjusted in this temperature center upwards. This is done using so-called fumed. Fumed may be substances that are released by the body or exogenous substances such as bacterial toxins. They set in motion processes that lead ultimately to the fact that the set point temperature in the center shifts.
Rarely are not pyrogens cause of the fever, but a direct stimulation of the temperature center due to strong emotions or brain damage.
Fever is a common side effect of many diseases. Especially infectious diseases and inflammation, which are caused by bacteria, viruses and fungi, often accompanied by fever, such as:

DRESS syndrome).
The rectal temperature measurement is considered the most accurate. Today, Electronic Digital Thermometer most common; older models are fever thermometer that detect the temperature with mercury or alcohol.
If you not Rektal want to measure, you must at all other measuring methods about offset of 0.5 ° C to the result.
If the fever persists, continue to rise or the person appears apathetic, you should see a doctor. In neonates and infants fever should always be checked by the pediatrician.
