Chikungunya (CHIK) is both an arbovirus transmitted by Aedes mosquitoes and an arthrogenic alphavirus, the clinical consequences of which were revealed in France by the southwest Indian Ocean outbreak (Mayotte, Reunion) in 2005-2006. The recent epidemic spread of CHIK in the French South American and Pacific territories (departments) and communities led to a steady increase of infected individuals, confronting local and metropolitan healthcare professionals with the difficulties http://dx.

Addictovigilance is a health vigilance dedicated to the survey of medicinal or illicit psychoactive substance use disorders (SUDs). France is the only European country to have a vigilance system specifically dedicated to substances with an abuse/addiction potential. The French Addictovigilance system is organized in a network of regional tertiary centres (called Abuse and Dependence Monitoring Centres, CEIP-Addictovigilance) and works in close collaboration with Regional and National health authorities. Because of the essential and unavoidable nature of their practice in the French Healthcare system, general practitioners (GPs) are key actors to identify and track Addictovigilance signals. They have been involved in several of the pharmacoepidemiological surveys implemented by the French Addictovigilance Network (FAN). Now, they increasingly participate in clinical research projects and studies. In this article, interactions between GPs and the FAN are illustrated with two examples: patients on opioid substitution treatment and patients on opioid analgesics. Collaborations between GPs and the FAN could be further potentiated. In particular, more effective communication on psychoactive SUDs including abuse/addiction is necessary to optimize the implementation of preventive measures for patients on psychoactive substances medications, and to improve the attitudes of GPs and more widely health professionals in the management of any psychoactive user suffering from SUDs. In addition, both adapted training and improved collaborative research could contribute to the optimization (safety, quality) of professional practices.

These data illustrate a previously underreported variability of the medical risks in various maritime routes; and help promoting targeted medical interventions including the implementation of onboard point-of-care laboratories, to further increase the rapidity of the diagnosis and the medical management onboard cargo ships.
