Tonsillitis (throat inflammation) is a common disorder in children.
Causes of Tonsillitis
In most cases, tonsillitis is caused by viruses, but a child can also get it by bacteria, for example streptococci.
The bacterium or virus is usually transmitted via the air. Minuscule droplets are spread in the air by sneezing, coughing and breathing and inhaled by someone else. In this way, the bacterium is passed easily.
A doctor will want to look closely at the tonsils to see if they are inflamed. They are often reddish and swollen, often white spots are visible. In general, it is not necessary to carry out additional research. Additional research will take place if there is a suspicion of Pfeiffer's disease or if the tonsillitis is severe and lasts an exceedingly long time. The doctor will then perform one or both of the following investigations:
If the tonsillitis persists, or causes complications, it may be necessary to remove the tonsils surgically.
