We were informed by two of our attendees that they had tested positive for COVID-19 days after our event. We took quick action to contact the Massachusetts Department of Public Health to ensure we had the correct information and most comprehensive communication plan for the rest of our guests. They confirmed that releasing specific names would be a violation of privacy law, but that the instinct to alert attendees as soon as possible was correct. We sent an email notification immediately thereafter to all attendees about the situation, and a second email shortly after to clarify that proper health departments had been notified and consulted, along with information about how to work with their doctor appropriately should they be concerned for their personal health. It was a priority for us to follow the safety and communication protocol we have been given by the CDC and the Department of Public Health for the well-being of all involved. We continue to support our partners, attendees, and colleagues through this challenging time and encourage everyone to take the necessary safety precautions as recommended by the CDC and Department of Public Health.
