Key Points

• In week 25, SARS-CoV-2 continued to circulate in the population, but the impact on the healthcare system remained moderate.

• All indicators were on the rise but remained below the levels seen during the last two waves, particularly for emergency department visits and hospitalizations following those visits.

• Waves of COVID-19 have already been observed in the spring and summer since the start of the pandemic. They are not systematically linked to the emergence of a new variant, but may be related to individual immunity and population behaviors that can facilitate virus transmission.

• In the context of active SARS-CoV-2 circulation, adopting preventive measures remains an effective way to protect against respiratory infection and its complications by limiting the risk of transmission to others, particularly vulnerable individuals: wearing a mask if symptomatic and washing hands.
