[Survey of the recommendations given to travelers to tropical zones]

This inquiry, conducted with the collaboration of 250 doctors, 150 pharmacists and 76 travel agencies in the Canton de Vaud was set up to assess the prophylactic advice given against tropical diseases. Replies concerning major affections are discussed. It appears that in a high proportion of cases the recommendations available to travellers are inadequate, due in part to lack of precise, standardised and up to date information.
