COVID-19 measures

Update: 1 November 2022


Please check the website of the Dutch government for the latest news on COVID-19 measures. 

For our future visitors we have implemented the following safety measures and guidelines.

Precautionary measures

The Lorentz Center and Leiden University always follow the health advice of the National Institute for Public Health and the Environment (RIVM) and the travel advice of the Ministry of Foreign Affairs.

Together, we’ll get coronavirus under control. Follow the RIVM’s measures to avoid contracting or spreading the virus:

  • Wash your hands regularly with soap and water.
  • Use an alcohol-based hand sanitizer if soap and water are not available.
  • Sneeze or cough into your elbow or cover your mouth and nose with a tissue (not your hands). Dispose of tissues immediately and wash your hands.
  • Make sure there is plenty of fresh air.

Precautionary measures at the Lorentz Center:

  • Wash your hands before getting a cup of coffee/tea.
  • If you have a cough or cold, stay at home or in your hotel room and do a test. Inform the Lorentz Center and/or the hotel reception.


What to do when you feel sick?

The Dutch government is asking anyone with a cold, cough, sore throat or fever to go into self-isolation and get tested. Don't leave your home, except to go to your test appointment.

If your symptoms worsen, call your doctor or the local branch of the Municipal Public Health Service (GGD) instead. For Leiden, this is GGD Hollands Midden at 088 308 30 00.
