Results The average bacterial count on hands of medical and nursing staffs of this hospital before medical operation was 51 cfu/cm^2 and that during medical operations was 32 cfu/cm^2. After washing with ordinary soap, the average bacterial count on hands was 24 cfu/cm^2. After wiping hands withquick hand disinfection solution containing isopropanol, the average bacterial count on hands was 4 ofu/cm^2. Conclusions The bacterial count on hands of medical and nursing staffs before washing and disinfection significantly exceeded the allowable limits. The decrease in bacterial count was not significant after washing hands with ordinary soap, while disinfection of hands by wiping with the quick hand disinfectant had good efficacy.
