The belief in vampire mythology was partly influenced by the physical transformation of the human body after death. The corpses were found to have grown long teeth and had bloating and red liquid seeping from the mouth, but these were the result of soft tissues in the fingers and hands contracting as they lost moisture and the belly expanding from gases. This happened to people who died of tuberculosis when there was no understanding of germs and disease and people were getting thin, pale, and weaker until they died.
