What causes infection?

Answer by  PietHeemskerk (133)

There are two types of infection: Bacterial and viral. Both tend to happen when parts of the human body that aren't meant to be exposed to the outside world, are. The introduction of bacteria usually follows, and these will attempt to reproduce. The immune system will attempt to fights this, which causes pain and swelling.
