The first challenge in EI seems to be in Early Detection (ED). For example, healthy looking normally born babies may also be harbouring deadly diseases (asymptomatic new born)! To fight this menace, the western world has started New Born Screening Program since Seventies. These are a set of tests, which can pick up the possibility of any underlying diseases in the apparently healthy looking new born. The reason these have to be picked up so early in their lives is that their problems will show at a predictable period later in their life. But, by that time, effects of hidden damages by the on-going disease process will render further management harder or impossible.
