Key points
In week 25, circulation of SARS-CoV-2 intensified throughout metropolitan France, as did new hospital admissions, particularly among the most elderly for whom vaccination coverage for the second booster shot remains insufficient.
- Metropolitan France:
- Sharp increase in incidence rate in all regions and age groups
- Hospital admission rate rising and particularly high in the 80+ age group
- Overseas France:
- Virological indicators still at very high levels, although decreasing in Martinique
- Increase in the incidence rate in Guadeloupe and French Guiana
Variants
- BA.2 gradually replaced by the now dominant BA.5 with 59% of interpretable sequences in the week 24 Flash Survey (13 June)
- Increased presence of the mutation at position L452 in screening (74% in week 25 vs 64% in week 24), connected with the increase in certain Omicron sub-lineages, including BA.5
Prevention
- Vaccination on 27 June 2022 (Vaccin Covid data):
- Vaccination coverage for the booster shot remained stable at 74.6% in the population aged 18+ and 84.5% in the 65+ age groupOnly 25.5% of 60-79 year-olds and 31.3% of 80+ year-olds eligible for the second booster shot had received it
- With the increasing circulation of SARS-CoV-2, adopting combined measures is essential, particularly to protect the most vulnerable populations:
- It remains important to self-isolate in the event of symptoms or a positive test for COVID-19
- It is crucial to apply individual precautions against infection, including wearing a mask (especially in closed areas, at large gatherings, around vulnerable people and on public transport), hand washing and frequent ventilation of enclosed spaces
