What can be done to prevent the infection?
Appendicitis cannot be prevented.
What are the long-term effects of the infection?
Untreated appendicitis may lead to peritonitis, which is an infection in the abdominal lining. Untreated appendicitis may also lead to a ruptured appendix. Some people get over an attack of appendicitis without having surgery. However, they may later have episodes of chronic appendicitis or bowel blockages.
What are the risks to others?
Appendicitis is not contagious, and poses no risks to others.
