[Chikungunya outbreak on Reunion Island in 2005/2006: role of hospital physicians in raising alert]. / L'epidémie de chikungunya de la Réunion 2005-2006; place du médecin hospitalier dans l'alerte et la gestion de l'epidémie.

The epidemic of chikungunya (CHIK) that swept through Reunion Island from late 2005 to mid 2006 affected 38.2% of the population, i.e., 300000 people. Although this outbreak took place in a French overseas department with high public health standards, failure to anticipate a large-scale epidemic associated with unprecedented severity and unexpectedly high mortality led to a major public health crisis. The purpose of this report is to provide a complete account of the experience of hospital intensive care physicians in addressing problems ranging from discovery of severe forms to management of a major health crisis. This report underlines the role of the head hospital physician and the necessity of mutual trust and collaboration with supervisory authorities.
