Yes this information is in the CDC report, take a look at the seating chart with annotated infection and symptom status [1]. > 12 became infected Using the word became is disingenuous at best (and misinformation at worst) because it implies that causation was established, but it was not. Here is the exact language from the CDC report: > Students were seated in five rows; the attack rate in the two rows seated closest to the teacher’s desk was 80% (eight of 10) and was 28% (four of 14) in the three back rows (Fisher’s exact test; p = 0.036) Because the students were only tested after the teacher tested positive, there is no way to determine causation from positive test results. Even the evidence from genome sequencing could only establish correlation, but not causation. > Eleven sequences were genetically indistinguishable from one another [...] Among the indistinguishable specimens, six were from students of the index patient, four were from students in the separate grade, and one was from a sibling of a student in the index patient’s class, suggesting that infections occurring in the two grades likely were part of the same outbreak.
