Objective@#To understand prevention and control of infectious disease among primary schools in Xi’an. @*Methods@#A total of 93 primary schools were selected through multi-stage stratified sampling method from 14 counties in Xi’an, then these schools are surveyed to meaure the classroom ventilation.@*Results@#About 28.0% (26/93) of these schools met the national standard for health staffs, with 7.4%(4/54) in urban primary schools and 56.4% in rural primary schools (22/39), the difference between urban and rural areas is statistically significant(P<0.01).

The average per capita area among the 92 primary schools was (1.22±0.34) m2, with (1.08±0.26) m2 in urban primary schools and (1.42±0.33) m2 in rural primary schools, the difference between urban and rural areas was statistically significant (P<0.01). The average per capita ventilation area of 92 primary schools was (0.15±0.07) m2 with (0.13±0.04) m2 in urban primary schools and (0.19±0.08) m2 in rural primary schools, the difference between urban and rural areas was statistically significant (P<0.01).@*Conclusion@#School-based infectious diseases prevention and control needs to be improved in Xi’an, especially in health personnel.
