Auvergne-Rhône-Alpes Regional Health Agency (ARS) is sounding the alarm. Since mid-January, 25 cases of measles have been detected in the Rhône department.

Of these 25 cases, 22 concern children, nine of whom are under 13 years old. Five of them had to be hospitalized. This start of the epidemic comes in a context of resurgence of measles by the World Health Organization (WHO) and Public Health France, particularly in Europe.
