How many only 'tested positive', or simply got too close to someone that 'tested positive', and had no actual symptoms?

"West Virginia’s young school year is running into some turbulence already from covid-19:

-All schools in Monroe County are being closed for several days because of covid-19.

-Barbour County Schools also went to remote learning this week after students and staff were identified with covid.

-Pleasant Hill School in Calhoun County went to remote learning the past couple of days because of covid-19.

-Jefferson County Schools announced this week that one of its classrooms would have to quarantine for the first time.

-Kanawha County, which started school early in August, has been particularly hard hit.

-Monongalia County, which returned to classrooms one week ago, reports seven covid cases among students at University High School and six cases at Clay-Battelle High, along with a handful of student quarantines at several schools.

Superintendent Eddie Campbell noted that last year’s guidelines would have sent entire classrooms home, but this year’s guidelines have meant performing contact tracing for students who came within a few feet of a confirmed case. Exposed students who have been vaccinated or who are wearing masks are not required to quarantine under the state’s guidance."
