Infections with Hepatitis B Virus (HBV) may lead to immunological disturbances and defects of cellular immunity and there is a need of clarification whether HBV infections are associated with infections with intestinal helminths. Methods: A community-based cross sectional study was conducted in Tezi town, Puge County of the Liangshan Prefecture, southwestern China from October 23rd to November 3rd, 2014. Four hundred and thirty eight people (median age = 37 years, IQR = 22–49) were enrolled in this study. Modified Kato-Katz thick smear was used to detect intestinal helminths. HBV DNA was quantified to confirm HBV infection. Results: Among the 438 participants, 9.1 %, 13.5 % and 30.6 % were infected with HBV, A. lumbricoides (L., 1758) and T. trichiura (L., 1771), respectively; 7.1 % (30/438) were infected with both A. lumbricoides and T. trichiura and 2.3 % (10/438) were co-infected with HBV and A. lumbricoides. The multivariate logistic regression analysis showed that age (21–30 years versus >50 years: OR = 6.66, 95 % CI = 2.15–20.68), drug abuse (OR = 6.96, 95 % CI = 1.11– 43.90), A.

  • Countdown to 2030: Eliminating Hepatitis B Disease, China Jue Liu,A Wannian Liang,B Wenzhan Jinga & Min Liua
    Policy & practice Countdown to 2030: eliminating hepatitis B disease, China Jue Liu,a Wannian Liang,b Wenzhan Jinga & Min Liua Abstract Hepatitis B virus (HBV) infection is a major public health problem worldwide. China has the world’s largest burden of HBV infection and will be a major contributor towards the global elimination of hepatitis B disease by 2030. The country has made good progress in reducing incidence of HBV infection in the past three decades. The achievements are mainly due to high vaccination coverages among children and high coverage of timely birth-dose vaccine for prevention of mother-to-child transmission of HBV (both > 95%). However, China still faces challenges in achieving its target of 65% reduction in mortality from hepatitis B by 2030. Based on targets of the World Health Organization’s Global health sector strategy on viral hepatitis 2016–2021, we highlight further priorities for action towards HBV elimination in China. To achieve the impact target of reduced mortality we suggest that the service coverage targets of diagnosis and treatment should be prioritized. First, improvements are needed in the diagnostic and treatment abilities of medical institutions and health workers. Second, the government needs to reduce the financial burden of health care on patients. Third, better coordination is needed across existing national programmes and resources to establish an integrated prevention and control system that covers prevention, screening, diagnosis and treatment of HBV infection across the life cycle. In this way, progress can be made towards achieving the target of eliminating hepatitis B in China by 2030. Introduction Cochrane Library databases for English language articles and the China National Knowledge Infrastructure and Wanfang Hepatitis B virus (HBV) infection is a major public health databases for Chinese language articles.

  • Global Health Threats and Fashioning out Effective Responses to Them
    Foreword by Yanzhong Huang Throughout recorded history, disease has consistently accounted for the greatest proportion of human morbidity and mortality, far surpassing war as a threat to human life. In the post-Cold War era, the threats to the health of populations from infectious diseases have actually increased, as diseases do not respect territorial borders and the burgeoning global activities make national borders increasingly porous. The anthrax attacks of 2001 and the recent SARS epidemic only highlight the importance of health as a national security or foreign policy issue. As threats to the health of populations gain prominence on the public policy agenda, decision makers face a host of thorny questions. Should a comprehensive strategy for biological security emphasize improvement in international public health? What is the best approach to engage the public sector and the pharmaceutical industry in building our biodefense? What roles should be played by the international organizations such as the World Health Organization to ensure maximum protection from infectious diseases with minimal disruption? To effectively address these concerns, policy makers and scholars alike must transcend traditional models of inter-state conflict and develop new tools of analysis in assessing the nature of global health threats and fashioning out effective responses to them. Against this background, the Whitehead School of Diplomacy launches its Center for Global Health Studies, which will examine global health issues from a foreign policy and national security perspective. Among its functions, the Center will develop coursework, curricula and symposia to train leaders, practitioners, and policy makers. Bringing together public, private and academic partners, the Center will serve as a think tank and resource center on issues relating to health policy, development, and international security.
