M. Roll et al., NOSOCOMIAL SPREAD OF HEPATITIS-B VIRUS (HBV) IN A HEMODIALYSIS UNIT CONFIRMED BY HBV DNA-SEQUENCING, The Journal of hospital infection, 30(1), 1995, pp. 57-63
An outbreak of hepatitis B virus (HBV) infection in a haemodialysis un
it is described. Four patients in the unit contracted subclinical HBV
infection within three months. DNA sequence analysis of the S gene of
HBV isolates from chronic carriers and newly infected patients in the
unit aided in tracing possible transmission pathways. Three newly infe
cted patients had received partial or complete HBV vaccination previou
sly. HBV was rapidly cleared from all three although the anti-HBs titr
e had not reached 10 IU L(-1) in any of them at the time of infection.
