Brazil
"[R]ather than comply with an American demand that all foreign recipients of AIDS assistance must explicitly condemn prostitution, Brazil has decided to forgo up to $40 million in American support....
'Our feeling was that the manner in which the Usaid [sic] funds were consigned would bring harm to our program from the point of view of its scientific credibility, its ethical values and its social commitment,' Pedro Chequer, director of the Brazilian government's AIDS program, said... 'We must remain faithful to the established principles of the scientific method and not allow theological beliefs and dogma to interfere.'...

Canada
"The Supreme Court of Canada has struck down the country's anti-prostitution laws in a unanimous decision, and given Parliament one year to come up with new legislation — should it choose to do so.      
In striking down laws prohibiting brothels, living on the avails of prostitution and communicating in public with clients, the top court ruled Friday that the laws were over-broad and 'grossly disproportionate.'
'Parliament has the power to regulate against nuisances, but not at the cost of the health, safety and lives of prostitutes,' wrote Chief Justice Beverley McLachlin in the 9-0 decision that noted 'it is not a crime in Canada to sell sex for money.'"

Germany
"An estimated 400,000 prostitutes work in Germany, and 1.2 million customers are said to use their services daily. Revenues are estimated at 6 billion euros every year - equivalent to those of companies like Porsche and Adidas.

Greece
"Greece, whose ancient civilisation introduced the world to high class prostitutes in the sixth century BC, has at last decided to salute their contribution to society.
Athens has announced that its economy is 25% bigger than thought thanks, in part, to the round-the-clock duties of the country's prostitutes, who were known as hetairai in ancient times. The Greek authorities are revising the country's gross domestic product (GDP) after deciding that the black market should be included in the figures."

Hungary
"In an effort to bring prostitutes into the legal economy, officials said Monday that Hungary will allow sex workers to apply for an entrepreneur's permit - a move that could generate government revenues from an industry worth an estimated $1 billion annually...
The permits allow prostitutes to give receipts to customers and become part of the legal economy by paying taxes and making social security contributions, said Agnes Foldi, head of the Hungarian Prostitutes' Interest Protection Association.
Hungary's sex industry - including prostitution and the production of pornographic materials - generates an estimated $1 billion annually, said Agnes Bakonyi, the spokeswoman of Hungary's tax authority APEH...
Prostitutes in Hungary, can work legally only within certain zones - distant from schools and churches - and must get regular medical checkups. Pimping and bordellos are banned."

Isreal
"The Supreme Court on Monday rescinded a district court decision that awarded NIS [Israel Shekel] 150,000 in compensation to a disabled man to pay for sexual services. The plaintiff, 31, was seriously injured in a car crash in 1988 as a result of which he was diagnosed as suffering from a mental disorder and erectile dysfunction. His lawyer argued that ever since, his condition has necessitated visits to prostitutes....
Justice Eliezer Rivlin wrote in his decision that the claimant would not be given funds that would be used to violate the law by encouraging prostitution. 'The proper way of society to deal with prostitution has been subject for contention over many years,' Rivlin wrote. 'There are those who see prostitutes as slave laborers and others who claim there are those among them who make a calculated choice to make a living thusly. The difficult questions over prostitution shall not be resolved, here but we cannot ignore the fact that criminal law frowns upon it.'"

Peru
"Peruvian sex workers urged the government on Friday to regulate their profession, saying it would protect them from violence and help stop the spread of sexually transmitted diseases. Although prostitution is legal in Peru and in much of Latin America, sex workers said prostitutes should be allowed to work under license in 'tolerance zones.' To get and keep a license they would have to register with the government, submit to regular health checks and pay taxes.
'People have to understand that it's not simply about a whore standing on a street corner, it's a woman, a lady who's working,' said Angela Villon, president of the Civil Association of Sex Workers, at a news conference....
According to the health ministry, there are around 60,000 sex workers in Peru, 14,000 of them in the capital Lima, although Villon said she believed the true figures were higher."

Senegal
"Prostitution was legalized in this predominantly Muslim country in 1969, and today the government tolerates it as long as each prostitute registers with the state, is over 21 years old, and comes regularly to a center run by the Ministry of Health for checkups, education, and medical treatment. And that's a big reason why this West African nation of 10.5 million, according to the World Health Organization, has an HIV infection rate of about two percent while many of its nearest neighbors face rates several times higher; some Southern African countries, such as Botswana, report that a mind-boggling 39 percent or more of the adult population is infected."
