The Aspen Covid Testing lab team works to process COVID-19 tests on Friday, Jan. 22, 2021. (Kelsey Brunner/The Aspen Times) After seven days of declining COVID-19 case counts, Pitkin County will move back to Yellow level restrictions at 6 a.m. Saturday, the county’s public health director said Thursday. Thursday marked the seventh consecutive day that seven-day case counts were 90 or below, which is the maximum threshold for the Yellow level, said Jordana Sabella. That was enough for her to call state public health officials late Thursday afternoon and confirm that the county can move to the lesser restrictions as of Saturday morning.
