Finding F-1544

“In the campus, 55.0% of the indoor air samples were positive for at least one respiratory virus RNA.”

Structure

Factor: Airborne transmission
Setting: university building
Study design: sampling of indoor air for respiratory virus RNA on a university campus and in a hospital, with patient samples taken alongside (class 4)
Effect: share-above 55.0
Caveat: viral RNA in the air, which is not by itself evidence of infectious virus; the register has no slug for respiratory viruses, so the row is filed under airborne transmission

A Finding records what one published document states, verbatim and with its page. It is not a conclusion of Coridum; see the Claims that build on it.
