Abstract:
OBJECTIVE To detect the condition of bacteria of the air in wards of our hospital in order to reduce the possibility of air spread. METHODS Ten tuberculosis wards were chosen at random for study.Detected the bacteria content of the air in wards used before and after respectively and analysed the results. RESULTS The average of backgroud bacteria was 164 CFU/m 3 before the wards were used.Two years later,the average of bacteria increased to 682 CFU/m 3.The ratio was 1∶3:2 on average.There were significant differences between them. CONCLUSIONS Humen are the main facters that make the air polluted in these wards.The bacteria content will decline by good environment cleaning sanitation,ventilation and strengthening steriling management.Infection will decline in the hospital.
