I would like to thank you very much for your great efforts to design a difficult and very technical document. It saw the light of day last Wednesday 23 May and is on currently on the front page of the WHO website (and on our departmental web pages). We have received good feedback from experts, and the media pick-up was very positive with the right messaging !! It has been a pleasure working with you, and we hope to have your continued help for Part 2 (health risk assessment) sometime this summer.
