Two Northland schools were added to the Minnesota Department of Health's outbreak list Thursday.
A school building is put on the list if it reports five or more confirmed cases of COVID-19 in students or staff who were in a building while infectious during a two-week reporting period. The building is removed after 28 days of no new positive tests.
East High School, in Duluth, was added to the list Thursday. The school returned to four days a week in-person learning for all students April 1. Duluth Public Schools has had three staff cases and 20 student COVID-19 cases in the past 14 days, according to data updated Thursday.
Stella Maris Academy’s St. James campus was also added to the list Thursday. The school has an in-person learning model with a distance-learning option. It has had five cases within two weeks, Principal Julianne Blazevic said. She also said there has not been a positive case in a week and there’s been no transmission within the school.
“This is the highest number of cases we’ve had in two weeks all year,” Blazevic said. “Families really need to continue to be careful.”

Local COVID-19 numbers
Sixteen- and 17-year-olds continue to be vaccinated with the Pfizer COVID-19 shot. Over the past week, 7,357 more Minnesota teens received their first dose of the vaccine. The number of vaccines received by 16- and 17-year-olds in Northeastern Minnesota by county are:
Aitkin — 39.
Carlton — 154.
Cook — 28.
Itasca — 136.
Koochiching — 18.
Lake — 35.
St. Louis — 929.
In late March, Pfizer released results from a trial of 2,260 adolescents. the study found 100% efficacy in preventing symptomatic infection in children 12-15, and robust antibody responses and said the intervention "was well-tolerated."
The Food and Drug Administration is reviewing those data to make a determination on an Emergency Use Authorization for the population, one that could come shortly. Trials are also underway for effectiveness of the vaccines in very young children. Pediatricians expect those results won't be ready until 2022, however.
COVID-19 cases in St. Louis County youth continue to rise. Those ages 0-4 had eight new cases; ages 5-9 had 23 new cases; ages 10-14 had 32 new cases; and those ages 15-19 had 62 new cases in the past week.
Statewide COVID-19 cases over the past week by age group were: ages 0-4, 456; ages 5-9, 776; ages 10-14, 1,047; and ages 15-19, 1,433.
