Measles is a highly contagious disease characterized by respiratory symptoms, rash and fever. Complications are common. Despite national recommendations concerning the need to vaccinate children with 2 doses of MMR vaccine (at age 12 months and between 15 and 24 months), epidemic outbursts still happen. The treatment of infected children is purely supportive, whereas susceptible household contacts may benefit from IVIG or catch up with vaccination depending on their age and the time spent since the contact. This paper defines a practical approach for measles infected cases and contact patients.
