Health &Safety Guidelines

The American Crystallographic Association considers the safety of everyone at ACA2022 our top priority.  The ACA is preparing the ACA 2022 Annual Conference in-person event experience so that all individuals onsite—attendees, speakers, staff, and venue personnel—remain safe and comfortable throughout the event. To promote the safety of everyone at the event, the ACA will follow the guidance and requirements of the CDC, State of Oregon, Multnomah County Health Department, the Portland Marriott Downtown Waterfront and other local regulations regarding COVID safety practices. The ACA Health & Safety Guidelines may change from time to time in accordance with the Center of Disease Control and Prevention (CDC) guidelines and applicable federal, state, or local governmental orders, regulations, and/or guidelines intended to reduce the spread and risks of exposure to COVID-19.


ACA2022 Best Practices

As an attendee, your safety and wellbeing are our number one priority. With that in mind, the ACA will implement the following best practices:

  • Vaccination Requirement: All participants at ACA2022 whether a presenter, attendee, exhibitor, vendor, guest, or staff are required to be fully vaccinated, and if eligible, must have received a booster.  (see more details on vaccination requirements below) 

  • Masks: Face masks will be required in all indoor and outdoor spaces.

    • ​An acceptable “mask” is made of at least 2 layers of breathable fabric or hospital-grade material; fully covers the nose, nostrils, and mouth; fits firmly under the chin, and fits snugly, but comfortably against the side of the face.  Information on the different levels of face masks from the CDC can be found HERE.  

    • Face shields are not permitted.

  • Social Distancing:

    • All seating in session rooms will be set to accommodate current social distancing recommendations.  

    • Handshaking, hugging or other unnecessary person-to-person contact will be discouraged between all participants.

  • Symptoms & On-site Protocol:

    •  Please do not travel or attend ACA2022 if you are not feeling well or think you have been exposed to COVID-19 or other viruses.

    • If onsite and you become feverish or coughing, please stay in your room and notify ACA HQ [(716) 812-1652] to report illness - seek medical attention to obtain a COVID-19 test and do not return to the event until a negative test result is obtained.  

    • The ACA reserves the right to deny entry to anyone seeking admittance or remove them from the venue should they present any COVID-19 like symptoms or refuse to wear a mask.

  • Waiver & Acknowledgment: Attendees will be required to read, acknowledge and comply with code at all times relevant to the ACA2022 conference.  

  • Post Conference:  All registrants and guests who test positive for COVID-19 within 14 days after returning home from ACA2022 in Portland are asked to notify the ACA HQ by calling (716) 812-1652. Upon receipt of any such notification, and while maintaining the confidentiality of any attendee who reports a positive post-meeting COVID-19 test result, ACA HQ will notify all event attendees of their potential exposure to COVID-19 during the conference.
