Lasell University COVID-19 Dashboard

Lasell University COVID-19 Dashboard

The information in the dashboard below encompasses COVID-19 PCR testing of Lasell University students, faculty and staff as well as Lasell Village residents and staff. Lasell is partnering with The Broad Institute for all tests. Testing began on August 20, 2020 and will continue throughout the Spring semester (view the Fall semester dashboard). The University has instituted health and safety protocols to keep members of our community as safe as possible.

Test reporting is exclusively for tests conducted by Lasell University Health Services and Lasell Village in conjunction with the Broad Institute.

This dashboard presents metrics of regular, mandatory, repeated screening of all University students, staff, and faculty with an on-campus presence this Spring, and are not derived from individuals who solely undergo symptom-based testing. Lasell Village uses a different screening approach that may include symptom-based and other screening schedules for staff, residents, and others.

Glossary (in order of appearance of data): 

Tests performed: Total number of tests performed on the date indicated.

Cases: The number of positive test results. A positive test result means the SARS-CoV-2 virus was detected in an individual's test sample. Other test results include negative (most common) or invalid (see below).  

% Positivity: The ratio of the number of positive test results for a given day to the total number of tests performed on that day. 

Invalid Tests: Test results in which the sample was either inconclusive or not reported due to other issues, such as an individual not performing the swab correctly.

Median (min, max) turnaround time: The median number of hours (including the minimum and the maximum number of hours in parentheses) between the time of sample collection and the time the test result becomes available. This number includes the processing time at the Broad Institute, but is not solely a processing time metric, as all tests are delivered to the Broad Institute between 5pm and 8pm daily, whereas sample collection occurs between 7:30am and 4:30pm daily.

Cumulative across University and Village

Tests: Sum of tests to date since January 1, 2021.

Positive Tests: Sum of positive tests to date since January 1, 2021.

% Positivity: The ratio of the total number of positive test results since January 1, 2021, to the total number of tests performed in this period. 

Current Isolation, Quarantine, and Hospitalization: The number of students in isolation on campus as a result of a positive COVID-19 test. This number does not include individuals isolating at home. Current guidelines indicate isolation is a period of at least 10 days. Isolation is the separation of people who have tested positive to COVID-19 from people who do not have COVID-19. 

Quarantine: The number of students in quarantine on campus as a result of close contact with a positive case. This number does not include individuals quarantining at home. Current guidelines indicate quarantine is a period of at least 14 days. Quarantine is the separation of a person who has been exposed to someone with COVID-19 from people who have not been exposed. 

Hospitalization: The number of individuals (excluding Lasell Village) hospitalized. Individuals are not required to report hospitalization to Health Services. This value may not represent the true number of hospitalizations of University-affiliated individuals. 

Recovered, Cases last 7 days, Average daily % positivity

Recovered cases: Individuals (excluding Lasell Village) who have recovered from COVID-19 and are out of isolation after testing positive.

Average daily % positivity: The running average of the daily percent positivity.

% Positivity 7-day moving average: The running 7-day average of the daily percent positivity rate (ratio of cases [positive tests] to tests performed). This value allows for visualization of recent trends in positive cases relative to the total population sampled.

Population tested: The number of unique individuals tested as a part of the University's mandatory screening program, including students, staff, faculty, and other individuals (e.g., guests, contractors).

Case rate (% of population): The ratio of the number of cases (positive tests) to the number of individuals in the testing pool. This reflects the semester (or to date) incidence rate in the population. For example: 3.34 per 100 people at Lasell University tested positive for COVID-19 in Fall 2020.
