Hepatitis B virus (HBV) infection rates are declining, but infection with this virus or hepatitis C virus (HCV) remains a risk for dental health care personnel (DHCP). This article describes the epidemiology of HBV and HCV and their particular risks to DHCP. Hepatitis B vaccination is discussed, as is postexposure management recommendations for both HBV and HCV.

BACKGROUND To investigate the epidemiology of hepatitis B and C infections and the benefits of programs aimed at hepatitis prevention and control in Northeastern China. METHODS Individuals receiving health examinations were recruited to complete a questionnaire and undergo laboratory tests for hepatitis infection. Data on demographic characteristics, results of hepatitis B virus (HBV) and hep...

BACKGROUND Hepatitis C virus (HCV) is known to be a major cause of non-A, non-B hepatitis (NANBH) and is thought to be an important causative agent of serious liver disease. Recently the role of HCV in the development of various liver disease is suggested. METHODS Sera from 222 patients with various liver diseases had been kept frozen at -20 degrees C until the test. Anti-HCV was detected usi...

Liver biopsy is historically the gold standard for liver fibrosis assessment of chronic hepatitis C patients. However, with introduction and validation noninvasive tests (NITs) to evaluate advanced fibrosis, direct-acting antiviral agents treatment virus (HCV), role NITs have become even more complex. There now need longitudinal monitoring elucidation cutoff values prediction liver-related comp...

The rate of eradication of chronic hepatitis C considerably increases with direct-acting antiviral agents, particularly hepatitis C virus (HCV) polymerase inhibitors. While implementing full-length HCV NS5B polymerase sequencing in our clinical microbiology laboratory, we identified atypical HCV sequences, classified as subtype 2l, from 2 patients. HCV-2l NS5B polymerase sequences were detected...

We used PCR to detect hepatitis C virus (HCV) RNA among supernatants of ground Culex quinquefasciatus mosquitoes that (i) had been fed HCV-positive blood, (ii) had been intrathoracically inoculated with HCV-positive blood, or (iii) were from homes of hepatitis C patients. HCV RNA was detectable under all three conditions, but it did not replicate in mosquitoes and was not detectably transmitted...

Hepatitis C virus (HCV) has become the most significant cause of chronic liver disease of infectious etiology in the United States. The recognition that HCV can be transmitted perinatally or through blood transfusions warrants particular attention by the pediatrician. The American Academy of Pediatrics recommends screening infants born to HCV-infected mothers and persons with risk factors for H...
