Measles transmission risk among all students in (a) primary teacher self-contained versus secondary departmentalized schools and (b) schools with central forced air and ductless with and without air filter heating and cooling systems, (c) schools during cooling and heating seasons. *Transmission risks were significantly different based on nonparametric Wilcoxon rank sum tests with adjusted p-values for the sample size (i.e., \( P=1-{\left(1-0.05\right)}^{1/\sqrt{N_1{N}_2}} \), where N1 and N2 = number of iterations of compared scenarios)
