Key Points

In Week 22, virological indicators rose after several weeks of decline, while hospital indicators continued to fall nationwide. Incidence and positivity rates remained particularly high in Martinique.

• Mainland France:

  • Incidence and positivity rates rising in most regions

  • Less marked decrease in the hospitalization rate

• Overseas territories:

  • Very high virological indicators, still rising in Martinique

  • Confirmed resurgence in the incidence rate in French Guiana

Variants

• Omicron BA.2 sublineage dominant: 80% of interpretable sequences from the Flash S21 survey (05/23)

• Detection of BA.4 (1.1%) and BA.5 (18.0%) on the rise according to the Flash S21 survey

• Increase in the presence of the L452 mutation in screening (27% in S22), linked to the rise of certain Omicron sublineages including BA.4 and BA.5

Prevention

• Vaccination as of June 6, 2022 (Covid Vaccine data):

  • Vaccination coverage for the booster dose was 74.4% among those aged 18 and older (84.3% among those aged 65 and older)

  • Only 31.0% of those aged 60–79 and 28.4% of those aged 80 and older eligible for the second booster dose actually received it

• CoviPrev Survey, Wave 34 (May 9–16, 2022)

  • Continued decline in adherence to preventive measures, particularly mask-wearing

• Given the increased circulation of SARS-CoV-2, adherence to combined measures is essential, particularly to protect the most vulnerable populations:

  • It remains necessary to self-isolate in the event of symptoms or a positive COVID-19 test

  • It is essential for individuals to follow preventive measures, including wearing a mask (in the presence of vulnerable people and in crowded indoor spaces or at large gatherings), handwashing, and frequent ventilation of enclosed spaces
