Brazil releases 'good' mosquitoes to fight Dengue fever

Brazilian researchers in Rio de Janeiro have released thousands of mosquitoes infected with a bacterium that suppresses Dengue fever.

The hope is they will multiply, breed and become the majority of mosquitoes, thus reducing cases of the disease.

The initiative is part of a programme also taking place in Australia, Vietnam and Indonesia.

Julia Carneiro reports from Rio.
