One form of CSEC [commercial sexual exploitation of children] that has received considerable media and public attention over the past 15 years is child sex tourism or CST. It is sometimes referred to as sexual exploitation of children in tourism or SECT. Child sex tourism occurs in multiple tourism destinations and even in places which do not have any real tourism infrastructure. It is one of the greatest tests of an increasingly connected world and an important challenge to the ever-expanding travel and tourism industries. The purpose of this booklet is to give the traveller, the tourism professional, the government official, the interested NGO staff member, or simply the concerned individual, an overview of child sex tourism and what can be done to combat it.
