Prostitution in Ecuador is legal and regulated, as long as the prostitute is over the age of 18, registered, and works from a licensed brothel. Prostitution is widespread throughout the country. Many brothels and prostitutes operate outside the regulatory system and the regulations have been less strictly enforced in recent years. 25,000 prostitutes were registered in the year 2000. In 2007 it was estimated that 70% of the prostitutes in the country were from Colombia. The country attracts Colombian prostitutes as the currency is the US$ rather than the unstable Colombian peso. UNAIDS estimate there to be 35,000 prostitutes in the country.
