“…The family members only had point-of-care finger-prick screening for malaria and haemoglobin conducted. PNGDF personnel were screened via venous blood and sputum for lymphatic filariasis, haemoglobin levels, malaria, tuberculosis and arboviruses—Barmah Forest, Chikungunya, dengue, Japanese encephalitis, Ross River, West Nile and Zika 21–23. Vector identification and surveillance were also conducted in these three PNGDF military establishments.…”

Global Health Engagement is one method employed by the Australian Defence Force (ADF) in pursuit of its objectives to shape Australia’s strategic environment and to deter actions against Australia’s interests. Two recent examples of such engagements are malaria mitigation programmes led by the ADF Malaria and Infectious Disease Institute in partnership with the Vietnam People’s Army and the Papua New Guinea Defence Force. Both programmes were designed with extensive collaboration with host nation stakeholders, empowered local institutions and governance systems, built the capacity of the host nation with the aim of achieving independence from Australian support and met the strategic policy requirements of all nations involved. Process and outcome measures were built into both programmes, providing partner nations with the necessary assurance that funding was being used effectively. The long-term nature of each programme engendered personal trust between individuals and cultural understanding between military units. Recognising the value of formal education in the design and conduct of such programmes, ADF officers participate as students and instructors in the US Uniformed University of the Health Sciences course in Global Health and Global Health Engagement. Critically, this educational opportunity is afforded to future leaders in all professions related to health, including clinicians, military health planners and commanders. While an essential prerequisite to Global Health Engagement Programmes is their technical viability and validity, the most important key to success in the military context is a widespread understanding of how they achieve desired strategic effects for all involved.

Background Zika virus (ZIKV) has spread to five of the six World Health Organization (WHO) regions. Given the substantial number of asymptomatic infections and clinical presentations resembling those of other arboviruses, estimating the true burden of ZIKV infections is both challenging and essential. Therefore, we conducted a systematic review and meta-analysis of seroprevalence studies of ZIKV IgG in asymptomatic population to estimate its global impact and distribution. Methodology/Principal findings We conducted extensive searches and compiled a collection of articles published from Jan/01/2000, to Jul/31/2023, from Embase, Pubmed, SciELO, and Scopus databases. The random effects model was used to pool prevalences, reported with their 95% confidence interval (CI), a tool to assess the risk of study bias in prevalence studies, and the I2 method for heterogeneity (PROSPERO registration No. CRD42023442227). Eighty-four studies from 49 countries/territories, with a diversity of study designs and serological tests were included. The global seroprevalence of ZIKV was 21.0% (95%CI 16.1%-26.4%). Evidence of IgG antibodies was identified in all WHO regions, except for Europe. Seroprevalence correlated with the epidemics in the Americas (39.9%, 95%CI:30.0–49.9), and in some Western Pacific countries (15.6%, 95%CI:8.2–24.9), as well as with recent and past circulation in Southeast Asia (22.8%, 95%CI:16.5–29.7), particularly in Thailand. Additionally, sustained low circulation was observed in Africa (8.4%, 95%CI:4.8–12.9), except for Gabon (43.7%), and Burkina Faso (22.8%). Although no autochthonous transmission was identified in the Eastern Mediterranean, a seroprevalence of 16.0% was recorded. Conclusions/Significance The study highlights the high heterogeneity and gaps in the distribution of seroprevalence. The implementation of standardized protocols and the development of tests with high specificity are essential for ensuring a valid comparison between studies. Equally crucial are vector surveillance and control methods to reduce the risk of emerging and re-emerging ZIKV outbreaks, whether caused by Ae. aegypti or Ae. albopictus or by the Asian or African ZIKV.
