To sum it up, there are many cases of child abuse over the years; there have been almost 3 billion child abuse cases from 1998. The three main types of child abuse are physical abuse (50%), mental (30%) and emotional abuse (20%). Children who are abused at such a young age -especially infants and adolescents - are most likely to have a difficult life ahead. When they are sexually abused, they could be affected by STD (like AIDS), and when they are emotionally abused, they can be afflicted with mental problems such as depression, PTSD and such. Most abused children tend to have very poor communication skills as well, resulted by the horrifying conditions they have experienced before.
