. Remerciements, Ce travail a débuté alors que N.B. visitait l'Instituto Gulbenkian de Ciência, avec un financement du Portuguese Research Council (FCT) et de la Commission européenne (MEXT-CT-2004-14338). N.B. remercié egalement le Centre européen de contrôle et prévention des maladies pour son invitationàinvitationà une réunion sur la modélisation du chikungunya
