With the emergence of the COVID-19 Delta variant, mask recommendations are returning to parts of Maine as infections grow across the country. The protections that were achieved through moderate vaccination rates now may need to be supplemented with the use of face coverings to protect credit union members and employees.
Nationwide, Delta is reported to make up more than 80% of new infections. In Maine, that number is estimated to be at least 47% of new cases. Since the beginning of July, the average daily case number has quadrupled, likely due to the aggressive nature of the Delta variant. Delta is estimated to be 50% more contagious than the strains previously seen and can be transmitted by fully vaccinated people.
Both the federal and Maine CDC recommend wearing face coverings in public indoor settings in areas of substantial or high transmission—even for those who are fully vaccinated. Substantial transmission is defined as 50 to 99 new cases per 100,000 people in a week. High transmission is defined as 100 or more new cases per 100,000 people in a week.
As of Wednesday, July 28, only York and Piscataquis counties fell into the substantial transmission category. The rest of Maine falls into the moderate category. This could change if new cases increase.
Credit unions may require their members and employees wear masks in branches and may be recommended to do so on the basis of the current transmission levels in their county. Both the federal and state CDC continue to recommend vaccination as the best way to protect against all strains of COVID-19.
