title: [Study on the probability of hepatitis B virus infection at public service places].
abstract: OBJECTIVE
  To provide data for the control and prevention of hepatitis B and HBV surface antigen (HBsAg) status among the appliances and practitioners working in the public service places.
  
  
  METHODS
  63 beauty parlors, barber shops and bathing centers selected under stratified randomization sampling method and 682 workers were investigated through questionnaire. HBsAg from th e appliances of the public service places and employee was detected by RIA.
  
  
  RESULTS
  Two main sanitizing modes that including alcohol cleaning (34.60%) and ultraviolet light disinfection (30.79%) were used. The rates of testing on HBsAg among the appliances were 2.13% at the public service places, and were 0.63%, 2.67% and 3.70% in large-, medium- and small-sized appliances respectively. The rate of testing on HBsAg on large-, medium- and small- sized appliances were statistically different (chi2 = 6.68, P < 0.05). The positive rates of HBsAg on the appliances of beauty parlors, barbering shops and footbath inns were 2.97%, 0.61% and 3.42% respectively. People working in different service sites had different rates of HBsAg: those who worked at the 'acne needle' and the forceps were 5.13% and 4.17%. The positive rate of HBsAg among the workers in the public service places was 7.13%. The rates of HBsAgamong the workers in large-, medium- and small-sized public service places were 7.34%, 8.33% and 2.94% respectively. The rates of HBsAg among the workers in beauty parlors, barbering shops, footbath inns and bathing centers were 9.01%, 6.37%, 4.35% and 7.29% respectively. HBsAg positive rates were different among the workers working at different service sites: 13.33% at tattoo business, 12.68% in pedicles workers and 8.03% in massagists.
  
  
  CONCLUSIONS
  It is important to improve the sanitizing management of the appliances used in the public service places and to improve the knowledge, attitude, as well as practice of vaccination on hepatitis B among those populations.
