[Coverage of the chikungunya epidemic on Reunion Island in 2006 by the French healthcare system].

The chikungunya epidemic that occurred on Reunion Island between 2005 and 2006 was covered by the French health insurance system. This coverage involved a major increase in the number of paid sick leave days and prescription drug refunds in the first quarter of 2006. Special governmental measures such as full reimbursement of certain medications and waiving of the waiting period for sick leave in case of relapse greatly reduced the impact of the epidemic. Five years after, the database of the health insurance systems indicates a low incidence of chronic forms. Only cases managed on an outpatient basis were included in this study.
