Belgium’s Sars-CoV-2 contact tracing effectively curbed transmission, yet challenges persist in terms of delays, scalability and population adherence
Through contact tracing, researchers could reconstruct chains of linked cases by linking High-Risk Exposure Contacts (HREC) testing positive to their index case. We present chain-level descriptives, delays and an individual-level analysis of the events that determine chain progression. We used data from contact tracing outside of collectivities between September 2020 and March 2022 in Belgium. We present chain-level generation counts and structur…
Personal characteristics and transmission dynamics associated with Sars-CoV-2 semi-quantitative PCR test results
Introduction Following harmonization efforts by the Belgian National Reference Center for SARS-CoV-2, semi-quantitative PCR test (SQ-PCR) results, used as a proxy for viral load, were routinely collected after performing RT-qPCR tests. Methods We investigated both the personal characteristics associated with SQ-PCR results and the transmission dynamics involving these results. We used person-level laboratory test data and contact tracing data col…
Translating the Covid-19 epidemiological situation into policies and measures
The COVID-19 pandemic led to sustained surveillance efforts, which made unprecedented volumes and types of data available. In Belgium, these data were used to conduct a targeted and regular assessment of the epidemiological situation. In addition, management tools were developed, incorporating key indicators and thresholds, to define risk levels and offer guidance to policy makers. Categorizing risk into various levels provided a stable framework…
Key risk factors associated with fractal dimension based geographical clustering of Covid-19 data in the Flemish and Brussels region, Belgium
Introduction: COVID-19 remains a major concern globally. Therefore, it is important to evaluate COVID-19's rapidly changing trends. The fractal dimension has been proposed as a viable method to characterize COVID-19 curves since epidemic data is often subject to considerable heterogeneity. In this study, we aim to investigate the association between various socio-demographic factors and the complexity of the COVID-19 curve as quantified through i…
Effectiveness of contact tracing for Covid-19 in Belgium
Contact tracing and investigation can prevent infectious disease transmission when carried out promptly. Data obtained from contact tracing also provides unique information on transmission dynamics that can be useful for policy making. The proportion of secondary infections arising from index cases that were previously identified as a close contact, hence “known index cases”, has been indicated by ECDC as a key performance indicator for contact t…
Covid-19 surveillance in the Flemish school system
We demonstrate that effective integration of case surveillance within an electronic school health system is feasible, provides valuable data regarding the evolution of an epidemic among schoolchildren, and is an integral component of public health surveillance and pandemic preparedness. The relationship towards community transmission needs careful evaluation because of age-different testing regimens. In the Flemish region, case incidence within s…
The response to flexibility
Since December 2005 the GAVI Alliance (GAVI) Health Systems Strengthening (HSS) window has offered predictable funding to developing countries, based on a combined population and economic formula. This is intended to assist them to address system constraints to improved immunization coverage and health care delivery, needed to meet the Millennium Development Goals. The application process invites countries to prioritize specific system constraint…
