From June 1 through September 15, 2020, almost 3,000 participants provided oral/nasal swabs for over 7,200 tests for SARS-CoV-2, and completed over 135,000 daily and weekly surveys about symptoms and potential exposure to COVID-19.

The following charts and graphs highlight our study findings thus far.

Self-Reported Connection to COVID-19

This graph highlights the percentage of people in the study who self-reported being exposed to someone with COVID-19, suspected they had COVID-19, or told us they had been diagnosed with COVID-19, during the study. It is easy to spot the time an outbreak occurred within the campus community.

Symptoms Experienced

This graph shows the percentage of participants who reported a potential COVID-19 symptom on their daily survey.

Risks Reported, by Week

This graph reports the percentage of people who reported they had some potential risk for COVID-19 over the past week in 6 different categories, on their weekly survey.

Perceived Likelihood of Having COVID-19

This graph shows the mean rating assigned by students, essential workers, and faculty/staff participants each day, when asked how likely they thought it was they had COVID, on a scale of 1 – 100 (one meaning not likely at all, and 100 meaning they were sure they had it). You can see when students’ perceived likelihood of having COVID-19 jumped up, during the outbreak in early July.

Total Number of Oral/Nasal Swabs Taken per Day

This graph shows the number of swabs taken from participants each day of the study, used for PCR testing to detect whether a participant was infected with SARS-CoV-2. All participants had swabs taken at both the beginning and end of the study (with rolling enrollment stretching from June 1 through July 17), and some also came in for additional testing because they had symptoms, had been exposed to someone with COVID-19, or were selected through our study surveillance system despite having no known symptoms or exposures.

Number of Surveys Taken per Day

Participants were asked to take a daily survey every day during the time they were enrolled in the study, until the final official day on August 18. This graph shows the number of surveys taken each day throughout the study – over 2000 per day when we were at peak enrollment!

Racial/Ethnic Breakdown of Participants

During the baseline survey, all participants were asked to specify their race and ethnicity, and responded as highlighted in this chart. Note that percentages sum to greater than 100% because participants were able to check all boxes that applied to them.

Gender Breakdown of Participants

During the baseline survey, all participants were also asked to specify their sex at birth and gender identity. These graphs show the breakdown of gender identity from this survey.
