Brazilian researchers in Rio de Janeiro have released thousands of mosquitoes infected with bacteria that suppress 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.
The intracellular bacteria, Wolbachia, being introduced cannot be transmitted to humans.

The bacterium Wolbachia is found in 60% of insects. It acts like a vaccine for the mosquito which carries dengue, Aedes aegypti, stopping the dengue virus multiplying in its body.

They will be part of an experiment designed to show scientists at the University of the Witwatersrand (Wits) whether irradiating male Anopheles arabiensis mosquitoes can help stop the spread of malaria.

Using sterilisation as birth control for insects is not a new idea. It was used to eradicate the screw worm in the US and Mexico in the 1980s, and in South Africa farmers have tackled fruit flies and coddling moth in much the same way. Male pupae are irradiated with a radioactive source such as Cobalt-60, and then grown to maturity in the lab.
