More than 500 people will gather at the venue and spend time together in the same room for extended periods. The effective air exchange in the meeting rooms by air-conditioning and other standard safety measures will reduce the risk of infection. Additionally, it is foremost in our own responsibility to contribute to minimizing the likelihood of viral spread during our anniversary event. The best way to achieve that is to adapt our behaviour to the situation. In particular:

1. We highly recommended a double vaccination plus a booster shot, especially for those of us over 60.
2. Although not obligatory, we strongly encourage you to wear an FFP2 mask at the venue, particularly in the session rooms when not speaking. We make this recommendation, although you will notice that masks are now worn much less in public than only a few months ago, and neither hotel staff nor hotel guests are required to wear them any longer. However, given evidence that FFP2 masks effectively reduce infection risks, we advise bringing a mask for every day to protect yourself and others. A limited number of masks will be available for a fee at the venue, but not nearly as many as would be needed for all conference participants.
3. We suggest regular self-testing, preferably before arriving at the venue and every morning during the conference and excursions. Please bring your own test kits. A limited number of kits will be available for a fee, although not nearly as many as would be needed for all conference participants.
4. If you test positive, or develop symptoms (e.g. coughing, fever), we urge you to stay away from the venue for five days after testing negative. This is important to avoid a spreading event at SIL 100. We count on your cooperation, even in the sad situation when you travelled a long way.
5. If you test positive, it is also advisable to (run a PCR) test at one of the numerous test centres. Please find below a list of a few of them not too far from the venue, as well as of some pharmacies.

FFP2 masks and test kits can also be purchased in local drugstores such as the Rossmann stores: https://www.rossmann.de/de/corona-schnelltest.
