• In the context of the summer holidays and activities that favour transmission of the virus, compliance with the combined measures remains essential:

  • up-to-date COVID-19 vaccination;

  • self-isolation in the event of symptoms or a positive test for COVID-19;

  • application of protective measures, including wearing a mask around vulnerable people or in enclosed spaces (public transport, large gatherings, etc.) and frequent handwashing.

During heatwaves, ventilation of enclosed spaces should be limited to the coolest hours of the day.
