More than 110 cases of COVID-19 have been reported at Lancaster County schools so far into the 2020-21 school year.
The cases come from 16 school districts, plus a brick-and-mortar charter school in Lancaster city and the county's career and technology center.
And that might not be all.
With the Pennsylvania Department of Health not tracking COVID-19 cases in schools, it's up to each district to notify the community of a positive test from someone inside its schools.
Reporting methods differ wildly from district to district.
Some schools have posted a letter online after discovering each positive test. Elizabethtown Area has added a "COVID-19 dashboard" showing the number of at each of its schools.
Hempfield, meanwhile, is publishing daily a simple "yes" or "no" as to whether it conducted contact tracing that day. The number in the list below, therefore, corresponds to the number of times the district has conducted contact tracing. The number of actual cases may be higher.
Some districts haven't published anything.
Only School District of Lancaster has specified whether the positive tests came from a student or a staff member.
With each case comes contact tracing, cleaning and sanitizing buildings and, in some cases, school closures.
Ten schools — Conestoga Valley High School, Donegal High School, Donegal Intermediate School, East High Street Elementary School, Elizabethtown Area High School, Elizabethtown Area Middle School, the Lancaster County Career & Technology Center, Pequea Valley High School, Pequea Valley Intermediate School and Penn Manor High School — have temporarily closed this fall due to COVID-19.
Below is a list of known school districts and individual schools that have reported at least one case of COVID-19.
Note: These are cumulative cases; some are no longer active.
