I00-I02: Acute rheumatic fever

I00: Rheumatic fever without mention of heart involvement

You have become infected some time ago with certain bacteria. You had a sore throat or tonsillitis caused by bacteria. Your immune system fought the bacteria using certain antibodies. However, these antibodies can also attack the body’s tissue.

This can lead to joint inflammation and later to heart problems. More rarely, one may also get skin inflammations or nerve disorders.

Also common is a high temperature and feeling generally ill.
