After months of single-digit weekly Covid-19 case numbers, Lincoln’s caseload shot up in the last two weeks of 2021, with 15 cases for the week ending December 23 and another 29 cases in the following week. This is the biggest two-week total since the beginning of the pandemic, surpassing the 27 cases seen in the last two weeks of 2020.
The spike mirrors that of neighboring towns as well as the rest of Massachusetts and the U.S. Over the same time period, Carlisle has recorded 73 positive cases, and there have been 190 in Concord, according to Public Health Nurse Tricia McGean. Local public health officials are responsible for tracking and contact tracing Covid-19 cases, but the state Department of Public Health recognizes that local boards of health don’t have the capacity to follow this surge “and suggests we try to focus on priority groups such as K-12, congregate living situations, daycares, and the like,” she said on December 31.
“That being said, the ones that I do contact generally have mild to moderate symptoms,” McGean continued. “Transmission often happens when groups gather, so I expect more and more cases each day after this holiday week.”
The omicron variant spreads three times as fast as previous variants, so once one family member tests positive, the virus often jumps quickly from one person to another, and “this is where I’m seeing most of the transmission in the cases I interview. One household case turns to two turns to three all in a matter of days,” she said.
McGean could not immediately provide data on the ages of those who have tested positive in Lincoln, but statewide, 40% of cases in the last two weeks of the year were in adults age 20-39, according to DPH figures.
Lincoln schools are reopening on January 3 after the holiday break with “heightened attention to known, effective precautions,” Superintendent of Schools Becky McFall said in a letter posted to LincolnTalk on December 30 by School Committee member Susan Taylor.
All student after-school activities are cancelled for the week, and families are asked to reinforce symptom checking and mask wearing. Teachers and all school employees were instructed to self-test before arriving to work Monday and will wear state-issued KN95 masks at all times indoors. School and health officials will reassess following the results of weekly pool testing, McFall said.
“I recognize that it is concerning that we are returning to school under conditions of increasing numbers of Covid-19 cases. This is not surprising, and while the numbers are higher, we are following a trend similar to last year at this time with a spike in cases following the holidays. If the pattern holds, we can hope to see a large decrease in cases at the end of January,” McFall added.
Since the start of the school year, the Lincoln Public Schools have recorded 82 cases of Covid-19 (68 students and 14 staff), according to the LPS Covid-19 dashboard. That includes nine cases each in September and October, 29 cases in November, and 35 in December. Sixty-one cases were on the Hanscom campus and 21 on the Lincoln School campus.
Lincoln-Sudbury Regional High School’s Covid-19 dashboard says there have been almost 60 cases of Covid-19 among faculty and staff as of January 3, up sharply from 17 during the week ending December 29.
Federal and state health officials have issued new isolation and quarantine guidelines for those who test positive or are exposed to someone with Covid-19. Regardless of vaccination status, anyone who tests positive is required to stay home for five days. If they have no symptoms or the symptoms are resolving after that time, they can leave the house but must wear a mask when around other people for another five days.
McGean said there is no concrete threshold for closing the schools and moving to remote learning in the event that cases in town continue to rise sharply in coming weeks. Any such decision will be made after discussion among McGean, Superintendent of Schools Becky McFall, the Lincoln Board of Health, the state epidemiologist, and the state Department of Elementary and Secondary Education.
