The German Pre-CHI 2022 event will follow the Covid-19 Measures of Ulm University and we will have many measurements in place to make our event safe:

• We urge participants to test themselves before taking part in the German Pre-CHI 2022 (e.g. by means of a rapid antigen test).
• We strongly encourage participants to test themselves in the morning of the second day. Some rapid antigen tests are available for free at the registration desk.
• We suggest that only persons who fulfil the 2G requirement (recovered or vaccinated) attend the German Pre-CHI 2022.
• We ask you to wear an FFP2 mask or a medical mask to protect yourself and others from infection.
• The established hygiene measures and distance rules should continue to be observed.
• Persons with symptoms similar to COVID or who are in quarantine are not allowed to enter the university.
