In General, a person has a fever when their body temperature is over 38°C. Fever itself is not a disease or illness, but something the body uses to fight infections caused by bacteria, for example. What can I do myself if I have a fever and when should I see a doctor?
What is a fever?
A fever is generally a response of the body’s immune system. In other words, fever is not itself an illness, but rather the body’s response to a variety of factors. These may include stress, colds, heat accumulation, as well as infections, tumours or metabolic disorders.
Note: Fevers should not be underestimated in babies, small children, older people, tumour patients or people with weakened immune systems.
