Scientists are testing why some people are more attractive to mosquitoes than others in order to produce a more effective mosquito repellant.
The Health Show presenters - Dr Ayan Panja and Dr Shini Somara - talk to Dr James Logan of the London School of Hygiene and Tropical Medicine who has found that certain people produce a natural repellant.
The Health Show is broadcast on Saturdays at 10:10 and 20:10 GMT and on Sundays at 07:10 and 23:10 GMT. The programme is supported by the Gates Foundation.
