The mean economic burden of sick students who were inpatient, outpatient and self-treatment were 1 712.75(95%UI=328.50-34 00.00), 213.70(95%UI=191.83-236.33) and 58.97(95%UI=43.00-77.69)RMB, respectively. The mean economic burden of transport, extra tutoring and cost of lost labor were 53.63(95%UI=43.98-63.58), 558.49(95%UI=381.40-774.01) and 695.62(95UI=630.25-767.29)RMB.
