CAIC22 Corona Safety Recommendations

The COVID-19 pandemic situation remains dynamic. In order to reduce the risk of infection onsite, we are counting on all involved to act responsibly and show solidarity. We thus would like to remind you of the following safety measures and are grateful for your support:

  • Try to keep a distance of at least 1.5m whenever possible
  • Wear a surgical or preferably an FFP2 mask over your mouth and nose
  • Pay attention to proper hand hygiene and sneezing etiquette

As a preventive measure, we advise you to apply all measures to reduce the risk of infection. In addition, the organisation team will regularly ventilate all conference rooms during the event and provide for sufficient disinfection facilities. A limited number of Covid-19 rapid tests and surgical masks will also be available for voluntary use at the reception.

Participants with symptoms of a cold or signs of respiratory illness are kindly urged not to come to the conference.
