The Massachusetts economy will be reopened using a four-phase approach, based on public health guidance.
The goal of this phased reopening plan is to methodically allow businesses, services, and activities to resume, while avoiding a resurgence of COVID-19 that could overwhelm our healthcare system and erase the progress we’ve made so far.
Each phase will last a minimum of three weeks and could last longer before moving to the next phase:
If public health data trends are negative, specific industries, regions, and/or the entire Commonwealth may need to return to an earlier phase
The Commonwealth will partner with industries to draft Sector-Specific Protocols in advance of future phases (example: restaurant specific protocols will be drafted in advance of Phase 2)
If we all work together to defeat COVID-19, we can proceed through each phase
