Since September 2023, Morocco has been facing an unprecedented measles epidemic, with nearly 25,000 suspected cases, including 6,300 confirmed, and 120 deaths. This situation has had repercussions in France, where a notable increase in imported measles cases from Morocco has been observed. Since January 1, 2025, 13 cases of measles imported or linked to an importation after a stay in Morocco have been reported in several French regions, bringing the total to 39 cases between 2024 and 2025. Among these cases, 12 involve children under 5 years old and 20 young adults. The majority of those affected were not vaccinated (23 cases) or were unaware of their vaccination status (9 cases). Moreover, 26 of the 39 cases required hospitalization, including 11 in January 2025 alone. Santé publique France emphasizes the importance of checking one's vaccination status before traveling, especially to areas with high endemicity, like Morocco. The measles vaccine is over 95% effective after two doses. For children, vaccination can be administered from the age of 6 months if traveling, with the full vaccination schedule to be completed later. People born before 1980 and not protected against measles should receive an MMR vaccine dose before departure. Healthcare professionals are urged to be vigilant when treating patients showing symptoms of measles, especially those who have recently traveled to Morocco or other regions where the disease is circulating. Due to the highly contagious nature of the virus, isolation and additional precautions are essential to prevent its spread in healthcare settings. It's also recommended that all healthcare workers who are not immune or whose vaccination status is unclear receive the MMR vaccine, including those born before 1980. Measles is a highly contagious viral disease, transmitted by air or direct contact. The most severe complications affect infants and young adults, potentially leading to pneumonia or acute encephalitis. There is no specific treatment, and prevention relies primarily on vaccination.
