Correlation does not imply causation

Correlation does not imply causation:When two phenomena regularly occur together,one does not necessarily cause the other.So you say women who have inflammation also come down with childbed fever,therefore the inflammation caused the fever.But that not necessarily true.Yes, yes, the inflammation comes first,then the fever,so it seems like the inflammation causes the fever.But by that logic, since babies usually grow hair before teeth,hair growth must cause tooth growth.
