Positive Covid-19 Cases Reported to RTSD


  • The charts on this page will be updated weekly and list confirmed positive cases of Covid-19 reported to RTSD by the Chester County Health Department (CCHD) in individuals who attend or work in RTSD. Inclusion on these charts does not mean that an individual contracted Covid-19 at an RTSD building or event. RTSD Health Services works cooperatively with the CCHD to provide notification, contact tracing and quarantine information to affected individuals. If you do not hear directly from RTSD Health Services or CCHD, it is because you are not considered at risk due to these cases. To ensure patient privacy, RTSD will not provide any further information regarding affected individuals.

From the Superintendent: Clarifying Student Cases the Week of 4/3-4/9

  • The RTSD Covid-19 dashboard for Saturday, April 3 through Friday, April 9 shows our largest spike in student cases (23). However, we still have strong evidence to suggest these cases are not resulting in in-school transmission. This rise in cases is a result of transmission in our community outside of school.  

    Dr. Walensky, Director of the CDC, said it best on April 9: “I want to be clear. As cases increase in our community, we expect cases identified in school will also increase. This is not necessarily an indication of school-based transmission.” 

    Radnor is an example of this phenomenon. Prior to our return from break (April 1-5), we had six new cases at RHS, three at RMS, and two at RES. Since we were on break, none of these students were in school, but we count them on our dashboard. 

    To demonstrate even further what is happening with community spread among our students, since April 6 at RHS we had nine new cases. None of these students were present in school last week. They either stayed home at the beginning of the week because they were not feeling well, or they are enrolled in our fully virtual program.  

    We thank our parents and students for monitoring your symptoms and staying home when you are not feeling well and letting us know about the positive tests. We all need to be aware that the virus is clearly spreading more rapidly among our students in the community outside of school.
