    Measles in France: virtual absence of circulation of the virus maintained in 2022

    Public Health France publishes annual measles surveillance data in France for the year 2022 marked, as in 2021, by a virtual absence of circulation of the virus probably linked to better immunity of the population.

    Posted on June 16, 2023

    Like the majority of European countries, France has recorded a significant decrease in the number of reported measles cases since April 2020 in connection with the COVID-19 pandemic, followed by almost non-existent viral circulation in 2021 which continued throughout 2022. The absence of resumption of active circulation of measles is probably linked in part to the containment established in France between the months of March and May 2020 and to the other recommended barrier measures (distancing, barrier gestures, wearing a mask, curfew), but it was then maintained, unlike the other respiratory viruses, until the end of the year 2022. This very high level of immunity can be explained on the one hand, by the observed improvement in the MMR vaccination coverage at 2 doses in infants born since 2018 who are subject to the vaccination obligation, and, on the other hand, by the immunity acquired during recent epidemics. In order to pursue the global goal of eliminating the measles virus,

    Measles: key figures for surveillance in France in 2022

    A total of 15 cases (including 5 imported after returning from a stay on the African continent and 10 indigenous cases) were declared in 2022. They occurred sporadically during the year and no secondary transmission was reported except for maternal-fetal transmission.

    Among these cases, 2 cases presented pneumonia, 5 were hospitalized, none in the intensive care unit. No deaths were reported.

    Only 6 departments have declared at least one case. No cases have been declared overseas.

    The reporting rate was 0.01 cases/100,000 inhabitants (imported cases excluded). The highest rate observed still concerned children under 1 year of age: 0.44 cases/100,000.

    Among the 6 autochthonous cases eligible for vaccination (aged ≥1 year and born since 1980), only one case, aged 3 years, had received 2 doses of vaccine, the other cases were not vaccinated (n=3 ) or vaccination status was unknown (n=2).

    Measles is one of the most contagious infections, with potentially serious complications, and potentially eradicable thanks to high vaccination coverage.

    Today, there is no specific treatment for the measles virus and only a very high vaccination coverage could allow the disease to disappear definitively.

    Vaccination against measles is mandatory for all children born from January 1, 2018. The first dose is administered at 12 months and the second between 16 and 18 months. People born since 1980 should have received a total of two doses of vaccine, regardless of their history with respect to one of the three diseases (Measles-Mumps-Rubella).

    In France, if there is an improvement in MMR vaccination coverage at the age of 2 years with the implementation of compulsory vaccination for infants, the objective of a vaccination coverage of 95% at two doses has not yet been reached and there are still under-vaccinated populations, particularly among adolescents and young adults or even among specific populations far from the health system.
