Approximately 30 of people newly infected with HBV do not know how they contracted. This risk can easily be eliminated using standard precautionary measures. Blood, saliva, or any other body fluid from an infected person that may touch a break or opening in a childs skin, eyes, or mouth. The truth is that transmission of HBV can sometimes occur in unusual ways. There is a need for more studies on this subject, properly planned, controlled and analyzed.ĭental treatment can be included among the risk factors of HBV and HCV infection. HBV replicates through an RNA intermediate and can integrate into the host genome. We know hepatitis B is easily transmitted through sex. HBV, a member of the Hepadnaviridae family, is a small DNA virus with unusual features similar to retroviruses. By Christine Kukka It’s Sexual Health Awareness month and a great time to test your knowledge about how hepatitis B is and isn’t spread sexually. This is more important in developing countries where the rate of hepatitis infected individuals is higher. Hepatitis B virus (HBV) infects more than 300 million people worldwide and is a common cause of liver disease and liver cancer.

Although these studies were from different geographical regions of varied socioeconomic status and study populations and assessed different dental procedures, using different types of statistical analysis, we found that, although weak, there is an all-time risk of HBV and HCV infection during dental treatment. Overall, 53 studies which met the selection criteria were evaluated. Relevant material was evaluated and reviewed. Vaccination effectively prevents infection and chronic hepatitis B virus carriage. It is acquired at birth or later via person-to-person transmission. Dental treatment may be one of such risk factors, and this aspect is addressed in the present literature review, drawing information from existing literature.Īn online database search was conducted, limited to publications from January 1999 to February 2012 on specific aspects of HBV and HCV infection, including articles on risk factors, markers of infection, dentistry, epidemiology and transmission. Chronic hepatitis B virus infection is a global public health threat that causes considerable liver-related morbidity and mortality. Hence, viral hepatitis transmission risk factors identification is the main way to reduce infection. A large number of patients infected with HCV might have non identifiable routes of viral acquisition. ![]() HBV and HCV transmission seems to be also acquired by non-parenteral and non-sexual routes. ![]() Different risk factors were found to be associated with the transmission of these viruses in various settings. Patients chronically infected either with hepatitis B (HBV) or hepatitis C virus (HCV) are at increased risk of developing cirrhosis, end stage liver disease and hepatocellular carcinoma.
