Supermodel Naomi Campbell has jetted to Brazil to help the country's battle against an epidemic of dengue fever.

Just two weeks after she was arrested on board a British Airways flight in Britain for allegedly assaulting a police officer during a luggage row, Campbell has successfully made her way to Rio de Janeiro on Brazilian airline TAM.

She left London on Monday night and plans to donate blood and raise awareness of the mosquito-borne disease - which has infected 55,000 people in Brazil and killed 67.

Before departing, she announced: "I have to help Brazil and will donate blood."

It's Campbell's first trip to South America since she was hospitalised there herself in February, for the emergency removal of a cyst.

At the time, the 37-year-old was in Brazil as the guest of Brazilian billionaire Marcus Elias.
