Child sexual abuse (CSA) is defined as forcing, coercing or persuading a child to engage in any type of sexual act and it is very important issue to be discussed. It has a profound impact on physical and mental health. As well as causing physical injury, it is associated with an increased risk of a range of sexual and reproductive health problems, with both immediate and long-term consequences. Some children may display signs, symptoms or clues raising the suspicious that sexual abuse has occurred. In the field of applied parasitology, there are many procedures related to the same anatomical site as where CSA occurs. Additionally, parasitic infections may be associated with CSA and their routine investigation may help to discover such abuse there is thus a need for protective service and child abuse law enforcement investigators to work together with the medical parasitologists to establish a safe panel of routine investigations to cases of child abuse.
