Article Synopsis
- - A study in Khan Hoa Province, Vietnam (2009-2012) found that 12.6% of pregnant women were infected with hepatitis B virus (HBV), and after two years, 1.9% of their children were also infected despite 76.6% receiving vaccinations.
- - Children whose mothers tested positive for hepatitis B e antigen had a higher risk of infection, even with complete vaccination, and other factors like mother's low body mass index contributed to children's HBV infection.
- - The research indicates a low rate of congenital HBV infection in Vietnam but highlights the need for more preventive measures, including anti-viral therapy for high-risk pregnant women.
The G7 presidency and universal health coverage, Japan's contribution.
Bull World Health Organ
May 2018
Problem: If universal health coverage (UHC) is to be achieved globally, it needs sustained promotion and political awareness and support.
Approach: During its presidency of the Group of Seven (G7) industrialized nations in 2016, Japan aimed to raise the issue of UHC to the top of the global health agenda.
Local Setting: Japan has promoted a health agenda at all of the G7 summits since 2000 that it has hosted.
Article Synopsis
- Diabetes Mellitus (DM) is increasingly prevalent in Vietnam, particularly in the central region, where previous data has been limited; this study aimed to assess the prevalence of DM and understand public perception among adults in Khánh Hòa Province.
- A cross-sectional survey involved 376 adults aged 20-70 years, capturing lifestyle data, medical history, and conducting physical and blood tests to determine DM risk factors; 7.2% of participants were found to have DM.
- Findings revealed that older age and obesity significantly increased the likelihood of DM, while a significant portion of the population remained unaware of the disease, indicating a need for better education and awareness programs.
Supported by GAVI Alliance, measles-rubella vaccination was introduced in Vietnam in 2014, involving a mass campaign among 1-14 year olds and routine immunization of children aged 9 months. We explore the impact on the incidence of Congenital Rubella Syndrome (CRS) during 2013-2050 of this strategy and variants involving women aged 15-35 years. We use an age and sex-structured dynamic transmission model, set up using recently-collected seroprevalence data from Central Vietnam, and also consider different levels of transmission and contact patterns.

A population census survey was conducted in Nha-Trang and Ninh-Hoa to collect demographic, social-behavioral data and disease burden on SPID. The study site covered a population of 353,525 residing in 75,826 households with 24,781 children less than 5 years.

Rubella-specific immunoglobulin-M and immunoglobulin-G were investigated in cord blood samples by enzyme immunoassay. Corresponding clinical-epidemiological data were analyzed and the national congenital rubella syndrome (CRS) incidence was estimated using modeling.
