I've heard of lots of ways that people are trying to stop mosquitoes spreading disease - but I never thought releasing more of them might be the answer.

To combat the Zika virus in Brazil and Colombia, scientists are releasing 18 million mosquitoes. But these aren't normal mosquitoes. They've been infected with bacteria called Wolbachia, which stop the insects passing on viruses such as Zika to humans.

Releasing small numbers of these infected mosquitoes has been shown to reduce disease, so I hope this idea will help to end the devastating impact of Zika.
