Brazil's government is supporting dating apps to promote safe sex for the Rio de Janeiro Carnival 2015.

As thousands of revellers are gearing up to celebrate the world's biggest carnival, the health ministry is capitalising on a safe sex campaign to speak to red-blooded youth about the dangers of having unprotected sex.

The campaign involves fake profiles of revellers being created on hook-up apps such as Tinder and Hornet which are purportedly interested in having unsafe sex. But when users contact them they receive warnings about the dangers.

Brazil's health minister Arthur Chioro, said: "We need to reach young people. Heterosexual as well as homosexual young people. And to reach them today, with a direct, informative language, that clears things up, and calls on adolescents and young people to have safe sex that respects their partners."

However, Rosette Pambakian, director of communications for Tinder, told IBTimes UK the campaign was not approved by Tinder and the profiles violate their terms of service so they will be deleted.

The government is also calling on people to be tested for AIDS and some 70 million condoms will be distributed nationwide during the five-day celebrations.

The carnival, which begins on Friday, February 13, is anticipated to be the world's biggest and best.
