Multimodal genomic surveillance for respiratory pathogens at four U.S. international airports
Early detection of outbreaks and emerging pathogens is critical for public health and global biosecurity. Airports, as major international travel hubs with dense, enclosed populations, are high-risk settings for disease transmission and potential pathogen introduction. The U.S. Centers for Disease Control and Prevention, in collaboration with Ginkgo Biosecurity and the University of Wisconsin–Madison, implemented air monitoring for pathogen surve…
Operational research in infectious disease outbreak response
Timely and effective response to infectious disease outbreaks depends on the rapid application of evidence-based policies. Operational research (OR) is conducted during emergency response to inform decision-making, and guide response strategies; however, there is no standardized mechanism for documenting how OR is conducted or communicated during outbreaks. The World Health Organization Disease Outbreak News (DONs) platform is a global reporting …
Development of seropositivity to Sars-CoV-2 over the course of the Covid-19 pandemic in adolescents in a longitudinal cohort study in Cebu, Philippines
COVID-19 was first reported in the Philippines in January 2020 and the country experienced several COVID-19 waves. Little is known on the seroprevalence of SARS-CoV-2 among adolescents in a developing country such as the Philippines. In this study, we incorporated testing for acute COVID-19 and SARS-CoV-2 seropositivity in an ongoing dengue study of 9- to 14-year-old participants enrolled in 2017. Acute febrile episodes were detected through acti…
Performance evaluation of an operational dengue forecasting system (D-Moss) in Vietnam
D-MOSS (Dengue forecasting Model Satellite-based System) was launched operationally in Vietnam in June 2019, providing near-real time dengue forecasts across all 63 provinces. Very few dengue forecasting systems have prospectively evaluated the performance of dengue forecasting under real-world operational conditions. This study comprehensively assesses D-MOSS dengue forecasting performance since operationalisation through both statistical accura…
The WHO Disease Outbreak News during the Covid-19 pandemic
During the Covid-19 pandemic, the World Health Organization (WHO) was an important public source of information – not only about the pandemic, but also thousands of other potential health emergencies. Here, we examine the 242 reports published in the WHO Disease Outbreak News (DON) during the first four years of the Covid-19 pandemic (2020 to 2023), and document the diseases and regions that were reported. We find that multinational epidemics of …
City-wide built environment Sars-CoV-2 detection for Covid-19 surveillance
Built environment surveillance has shown promise for monitoring COVID-19 burden at granular geographic scales, but its utility for surveillance across larger areas and populations is unknown. Our study aims to evaluate the role of built environment detection of SARS-CoV-2 for the surveillance of COVID-19 across broad geographies and populations. We conducted a prospective city-wide sampling study to examine the relationship between SARS-CoV-2 on …
Invasive mosquito surveillance in the United Kingdom 2020 to 2024
Here, we provide an update on invasive mosquito surveillance activities coordinated by the UK Health Security Agency (UKHSA) between May 2020 and November 2024. Aedes albopictus and Aedes aegypti are invasive mosquitoes and not currently established in the UK. Both are vectors of various arboviruses including emerging pathogens such as dengue. Therefore, their introduction into the UK poses a threat to public health. In 2024, vector surveillance …
The utility of infectious disease modelling in informing decisions for outbreak response
Infectious disease modelling plays a critical role in guiding decisions during outbreaks. However, ongoing debates over the utility of these models highlight the need for a deeper understanding of their exact role in decision-making. In this scoping review we sought to fill this gap, focusing on challenges and facilitators of translating modelling insights into actionable policies. We searched the Ovid database to identify modelling studies that …
Epidemiological and phylogenetic analyses of public Sars-CoV-2 data from Malawi
The COVID-19 pandemic has had varying impacts across different regions, necessitating localised data-driven responses. SARS-CoV-2 was first identified in a person in Wuhan, China, in December 2019 and spread globally within three months. While there were similarities in the pandemic’s impact across regions, key differences motivated systematic quantitative analysis of diverse geographical data to inform responses. Malawi reported its first COVID-…
Gaps and opportunities for data systems and economics to support priority setting for climate-sensitive infectious diseases in sub-Saharan Africa
Climate change alters risks associated with climate-sensitive infectious diseases (CSIDs) with pandemic potential. This poses additional threats to already vulnerable populations, further amplified by social factors such as gender inequalities. Currently, critical evidence gaps, along with inadequate institutional and governance mechanisms, hinder African states’ ability to prevent, detect and respond to CSIDs. Effective responses require transpa…
Bayesian model selection for Covid-19 pandemic state estimation using extended Kalman filters
Quantifying the uncertainty in data-driven mechanistic models is fundamental in public health applications. COVID-19 is a complex disease that had a significant impact on global health and economies. Several mathematical models were used to understand the complexity of the transmission dynamics under different hypotheses to support the decision-making for disease management. This paper highlights various scenarios of a 6D epidemiological model kn…
Association between HTLV-1/2 infection and Covid-19 severity in a migrant Shipibo-Konibo population in Lima, Peru
Objectives The migrant community of the Shipibo-Konibo indigenous people in Lima, Peru were extremely vulnerable during the COVID-19 pandemic. Additionally, infection with human T-cell lymphotropic virus type 1 and 2 (HTLV-1/2) is endemic in this population causing immunosuppression. The aim of the study was to describe the association between HTLV-1/2 infection and the clinical severity of COVID-19. Methods This was a cross-sectional descriptive…
