CASSS will follow guidances established by the facility hosting the conference and/or local and state health authorities in which the conference is located.

For the safety of all attendees, we expect everyone to take everyday preventive actions prior to, and during the conference, to stay safe and healthy. These actions include, but are not limited to:

• Avoid close contact with people who are sick.

• Wash your hands often.

Wearing a face mask throughout hotel common space and conference designated areas is recommended but not required.
