Situation update

In week 27, the deterioration of the situation continued to accelerate. The effective R value (SI-DEP) of 1.5 attests to the strong dynamic of virus transmission. The incidence rate increased in all age groups. This increase was the highest among 10-39 year-olds and impacted all regions. The Delta variant now represents the majority of viral sequences in metropolitan France. Contact tracing data confirm the sharp increase in the number of cases who attended public venues. As of 13 July 2021, 54% of the population had received at least one vaccine dose, and 42% were fully vaccinated. Given the strong increase in viral circulation, the start of the summer holidays, and the rapid spread of the Delta variant, it is important to encourage the vaccination of all eligible people by reinforcing incentives and facilitating access to vaccines in order to achieve a sufficient level of herd immunity as soon as possible. It is also crucial to maintain a high level of adherence to preventive measures, notably by limiting contacts at risk and self-isolating in the case of symptoms, confirmed infection, or contact with a confirmed case.
