Imunização contra hepatite B em auxiliares em saúde bucal: estudo transversal no sistema público de saúde do estado de São Paulo, em 2018*

Abstract

Objective: to investigate dental auxiliaries (DA) hepatitis B immunization in Brazilian National Health System (SUS) services in nine cities in São Paulo State, Brazil, in 2018. Methods: this was a cross-sectional study based on interviews using a questionnaire as well as evaluation of immunity using the anti-HBs test, evaluation of prior testing, test result and interpretation and guidance provided about hepatitis B. Results: of the 70 registered DA, 35 completed the course of vaccinations, 29 had negative anti-HBs test results, 16 had tested previously, and 43 did not correctly understand their result; there was association (p=0.025) between completed course of vaccinations and receipt of guidance. Conclusion: most DA received guidance about hepatitis B; however, a considerable portion did not complete the course of vaccinations and had negative anti-HBs test results; few DA had tested previously nor correctly interpreted the result; evidence was found of an alarming scenario in which there are severe shortcomings in DA hepatitis B immunization.

Inflammatory Processes, Viral Infections and Dental Practice during Covid-19

“…HBV has a high degree of pathogenicity and infectivity and can remain active for at least one week in dry blood and at room temperature. Its antiviral resistance is up to 100 times greater than that of the Human Immunodeficiency Virus (HIV) and 10 times greater than the virus that causes hepatitis C (HCV) (GARBIN et al, 2020) [13] .…”

“…That is why it is important to carry out seroconversion tests, as not all professionals who bring hepatitis B virus vaccines, in fact, have immunological protection, thus, necessary doses of reinforcement to stimulate adequate levels of to. It is recommended to perform quantitative anti-HBs tests one to two months after the last dose of the vaccination schedule (GARBIN et al, 2020) [13] .…”
