“…15 Nevertheless, the HBV prevalence from our study was lower than that the previous report among the general population in Thanh Hoa province (18.8%), 14 Thai Binh province (19.0%), 17 and Binh Thuan province (15.3%). 13 The lower prevalence rate observed in our study might be explained by the following reasons. Our participants were in an urban area, and most of them were in the young age group with relatively high educational level, implying that they could easily access health information and had higher health literacy, and conveniently receive medical services.…”

“…5,8 However, some studies reported that the prevalence of viral hepatitis infection among beauticians was similar to the general population, [12][13][14] and were not able to link being a beautician to an increased risk of acquiring viral hepatitis. [9][10][11] In Vietnam, several studies reported that the HBV prevalence in the general population based on positive hepatitis B surface antigen (HBsAg) ranges from 8.8% to 20.5%, [12][13][14][15][16] indicating a considerable problem for the health system. Meanwhile, the HCV prevalence based on positive antibody against HCV (anti-HCV) among the general population ranges from 0.35% to 2.2%.…”

“…The sample size was calculated using a formula for estimating a finite population proportion. 22 Based on a total of 336 beauticians, an anticipated prevalence of HBV among the general population of 15.3%, 13 a confidence level of 95%, and absolute precision of 2.5%, the sample size was calculated as 237. In order to overcome potential quality control lapses during processing and storing blood samples and missing questionnaire data, 247 participants (73.5% of the total number of beauticians in Quy Nhon) were ultimately recruited.…”

Objective: To determine the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among beauticians and to identify occupational risk factors associated with the infections. Methods:The cross-sectional study of 247 randomly enrolled beauticians was conducted in Quy Nhon City, Viet Nam. Knowledge, perceptions, and practices towards occupational risk of HBV and HCV infections were evaluated using an anonymous questionnaire. Blood samples were tested for hepatitis B surface antigen (HBsAg) and antibodies against HBV and HCV by chemiluminescent microparticle immunoassay. Viral genotyping by real time quantitative PCR was performed for those testing positives for HBsAg and anti-HCV antibodies.Results: The prevalence of HBV and HCV infections was 7.3% (18/247, 95% CI: 4.4-11.3) and 0%, respectively. Among HBsAg(+) subjects, 72.2% (13/18) were identified as being infected with HBV genotype B. Overall, 198/247 (80.2%) perceived that they are at risk of being infected by hepatitis through work. Nearly half of participants (43.3%) were not immune to HBV. Discussions:The prevalence of HBV and HCV infections among beauticians was comparable to the general population previously of Vietnam; no occupational risk factors associated with infections were found. This finding proposed that beauticians might not be a high-risk group for HBV and HCV infections. However, the study revealed a high proportion of persons susceptible to HBV infections suggesting that public health preventive strategies and vaccination targeting these professionals should be implemented.

“…Mother-to-child (perinatal) transmission is the most common mode of infection, followed by horizontal transmission from family members and close contacts during early childhood [1]. An estimated 6-25% of Vietnamese are chronically infected with HBV [2][3][4][5]. Hepatitis C virus (HCV) infection prevalence is lower, estimated at 0.5-4% [2,3,6].…”

“…An estimated 6-25% of Vietnamese are chronically infected with HBV [2][3][4][5]. Hepatitis C virus (HCV) infection prevalence is lower, estimated at 0.5-4% [2,3,6]. However, higher HBV and HCV infection prevalences are reported among people living with HIV (PLHIV) and at risk for HIV in Vietnam, ascribed to overlapping behavioral risks for HIV, HBV and HCV exposures [3,7,8].…”

This study assessed associations between hepatitis B and C virus (HBV, HCV) and increases in CD4 count and survival among 4316 HIV-infected patients on non-tenofovir (TDF)-based antiretroviral treatment (ART) in Ho Chi Minh City, Vietnam during 2006-2010, using mixed-effects model and survival analysis. More than half of patients (52.4%) participating in the study were HBsAg-negative/anti-HCV-negative, 9.0% HBsAg positive/anti-HCV-negative, and 38.6% anti-HCV-positive. Anti-HCV-positive males had smaller increases in CD4 count during the first two years of ART, but larger increases between two and three years after ART initiation than anti-HCV-negative females (regardless of HBsAg status) and HBsAg-negative/anti-HCV-negative males. Magnitude of the differences was small. Overall mortality rate was 15 per 1000 person-years; HBsAg and anti-HCV status were not significantly associated with mortality. Co-infection with HBV (HBsAg-positive) and/or exposure to HCV (anti-HCV-positive) does not seem to have substantial effects on outcomes of patients on non-TDF-containing ART during a median follow-up of 1.72 years. It may take a longer time for assessing effects of co-infection with HBV and/or HCV on ART outcomes. Such assessments should focus on those with positive HCV RNA, instead of positive anti-HCV.

High prevalences of hepatitis B and C virus infections among adults living in Binh Thuan province, Vietnam

Abstract: In Binh Thuan, prevalences of HBV and HCV infections are high, HBV genotype B and HCV genotype 6a are predominant, and horizontal HBV transmission may still occur. Therefore, raising the coverage of a universal HBV vaccination program may be an effective liver cancer control in Vietnam.
