A victory for evidence

Ever bought one of these? …Its an electronic gadget claiming to be able to repel mosquitoes by emitting a low frequency noise. Tempting, I suppose, since it seems quick and easy – no tablets to remember.

However a cochrane review - Electronic mosquito repellents for preventing mosquito bites and malaria infection – have found categorically that these devices don’t work. Regardless, they have been on sale widely including on board several major airlines.

Dr Bart Knols, who edits the MalariaWorld website decided to get busy and write to the airlines expressing his concern. Success: KLM have pledged to no longer sell them from March 2010 – KLM: An airline that acts responsibly – and responses are awaited from BA and Singapore Airlines.

A victory for evidence.
