'Happy Prostitute' ads in Brazil were banned from running online by the Brazilian Health Ministry for being too provocative and promoting prostitution, according to reports.

The 'Happy Prostitute' ads were supposed to educate prostitutes and their clients on the dangers of sexually-transmitted diseases, as well as reduce prejudice against sex workers. While prostitution is legal in the country, many say it sends a negative message ahead of the 2014 FIFI World Cup and the 2016 Olympics, according to a BBC news report.

The 'Happy Prostitute' ads featured prostitutes with the title "June 2 is International Prostitute Day" and included slogans that read: "I am happy being a prostitute" and "I cannot be seen without a condom, my love."

However, Brazilian Health Minister Alexandre Padilha dropped the 'Happy Prostitute' campaign on saying he didn't believe it was the type of message the country's health office should be sending out to the community.

"The role of the ministry is to have specific content to encourage prevention among sex workers, who are a very vulnerable group," he said.

Meanwhile, as the populous South American nation gears for the World Cup next year, prostitutes or sex workers are also getting ready for the big event.

As the nation prepares for the sports world stage, sex workers are getting ready as well. In the city of Belo Horizonte, prostitutes are lining up for free English classes so they can easily find new tourist clients and communicate with them.
