"This Wormy World": Global Atlas of Worm Infections - 25 August 2010

A global atlas of worm infections has been launched by scientists working in London and Nairobi. Simon Brooker of the London School of Hygiene and Tropical Medicine tells Peter Goodwin about "This Wormy World", a new on-line atlas that makes it easier for health workers to plan campaigns - such as programmes for de-worming school children - to reduce the burden of worm infections in areas most affected.
