Unusual cases of hepatitis b virus transmission

One reason some parents don’t vaccinate their children against the hepatitis B virus (HBV) is their belief that their child has no risk of ever coming in contact with the virus. “My child will never be sexually promiscuous or addicted to drugs! Why does he or she need to be protected against hepatitis B?” Of course, it is impossible to predict which children will grow up and engage in risky behavior. But let’s assume for a moment that this hypothetical parent is right . . . does this mean that his or her child has no possibility of ever coming in contact with HBV?The truth is that transmission of HBV can sometimes occur in unusual ways. Approximately 30% of people newly infected with HBV do not know how they contracted the virus. The following reports of some uncommon methods of HBV transmission illustrate how every unvaccinated person is at some (albeit limited) risk of HBV infection. 1. Between April 1984 and February 1985, thymectomy. The thoracic surgery physician- found 75 who developed HBV infection 24 cases of HBV infection occurred among in-training who assisted in surgery had had from 1991 to 1996.
