Sepsis – blood poisoning

Sepsis is a serious condition, formerly called blood poisoning. Sepsis means that an infection affects the entire body and that important organs such as the heart, lungs, brain and kidneys do not function properly. Sepsis can be life-threatening. It is important that you seek treatment immediately if you think you or a related person have received sepsis.


Fever in children

Fever is one of the body's ways of defending itself against infections caused by viruses or bacteria. Children get light fever, but that does not mean that they are particularly ill. The important thing is how the child feels otherwise.



Fever means that the body temperature is higher than it usually is. You may have a fever associated with a viral infection, such as a cold. The fever may also be due to an infection caused by bacteria.


Infection and inflammation

An infection means that the body has been attacked by bacteria, viruses or fungi. To defend itself, the body usually reacts with inflammation. The area that is inflamed can become swollen, red, hot and tender. Fever, fatigue, muscle pain, headache and decreased appetite are signs of a more widespread inflammation.
