ABSTRACT
OBJECTIVE To discuss the possibility of HBV contaminating environment and transmission through the polluted surroundings. METHODS On the basis of that ascertain the contaminated environment by HBV marker(HBVM) and the relationship between HBVM and HBV infectivity in the blood,to discuss the probability of HBV contaminating and be spreading through the circumstance. RESULTS The positive rate of HBsAg and HBeAg was 26.39% and 11.11%,respectively in these specimens.While all of samples in control group were negative.The HBV DNA positive rate was 73.72% and 100.00%,respectively in the positive blood specimens of HBsAg and HBeAg.The infectivity was 0-10~9 and 10~2-10~9 ID/ml,respectively. CONCLUSIONS The blood worktable surface is contaminated by HBVM.The pollution is from patients′ blood.So the probability exists that HBV is transmitted through environment pollution.
