Why the growth of arboviral diseases necessitates a new generation of global risk maps and future projections

Oliver J. Brady et al.
PLoS Comput Biol 21(4): e1012771

Global risk maps are an important tool for assessing the global threat of mosquito and tick-transmitted arboviral diseases. Public health officials increasingly rely on risk maps to understand the drivers of transmission, forecast spread, identify gaps in surveillance, estimate disease burden, and target and evaluate the impact of interventions.

Identifying the climate sensitivity of infectious diseases: a conceptual framework

Alcayna, Tilly et al.
The Lancet Planetary Health, Volume 0, Issue 0, 101291

Infectious diseases pose a substantial threat to public health, affecting billions and straining health-care systems worldwide. There is growing concern over how anthropogenic climate change might aggravate the global burden of climate-sensitive infectious diseases. In this Personal View, we propose a framework for understanding what makes an infectious disease climate-sensitive.

Integrating anticipatory action in disease outbreak preparedness and response in the humanitarian sector

Tilly Alcayna et al.
BMJ Global Health 2025;10:e017721

In the humanitarian sector, anticipatory action entails acting ahead of predicted hazardous events to prevent or mitigate potential impacts and needs. It leverages early warnings to bridge preparedness and response, with a core principle being the provision of ex-ante emergency funding for preagreed early actions. Traditionally applied to extreme climatic events, there is growing interest in integrating anticipatory action into disease outbreak preparedness and response. We present an analytical framework for trigger development for climate-sensitive infectious disease outbreaks based on a review of existing and emerging practices from the Red Cross Red Crescent Movement, United Nations agencies and Médecins Sans Frontières since 2014. We propose that, depending on data availability, there are four broad approaches for trigger development.

Effects of mosquito-proofing storm drains on adult and larval mosquito abundance: Protocol of the IDAlErt storm drAin randomiSed controlled trial (IDEAS)

Marina Treskova et al.
MethodsX, Volume 14, 2025, 103102

Aedes and Culex mosquitoes, vectors of diseases like dengue and West Nile, breed in urban storm drains with stagnant water, a problem that may worsen in Europe due to climate change. To address this, the Agència de Salut Pública de Barcelona (ASPB) tested structural drain modifications in a randomised controlled trial, assigning 44 drains to either mosquito-proofing or no change and monitoring them weekly from June to November 2023. Outcomes focused on adult mosquito counts and presence of adults and larvae, with results to be analysed using statistical models to assess effectiveness and guide possible city-wide adoption.

Strengthening resilience to emerging vector-borne diseases in Europe: lessons learnt from countries facing endemic transmission

Charnley, Gina E.C. et al.
The Lancet Regional Health – Europe, Volume 53, 101271

Emerging vector-borne diseases (VBDs) are a major public health concern worldwide. Climate change, environmental degradation and globalisation have led to an expansion in the range of many vectors and an erosion of transmission barriers, increasing human exposure to new pathogens and the risk for emerging VBD outbreaks. Europe is potentially underprepared for the increasing threat of VBDs, due to attention and funding being diverted to other public health priorities. Proactive, rather than reactive, prevention and control approaches can greatly reduce the socio-economic toll of VBDs. Endemic countries globally have decades of experience in controlling VBDs, and Europe has much to learn from this knowledge. Here, we advocate for the expansion of transdisciplinary knowledge-sharing partnerships, to co-create proactive measures against VBDs. We present the experiences and expertise of our diverse international team and explore how an array of interventions can be applied and adapted to the European context.

Harmonizing Multisource Data to Inform Vector-Borne Disease Risk Management Strategies

Lowe R, Codeço CT.
Annu Rev Entomol. 2025 Jan;70(1):337-358.

In the last few decades, we have witnessed the emergence of new vector-borne diseases (VBDs), the globalization of endemic VBDs, and the urbanization of previously rural VBDs. Data harmonization forms the basis of robust decision-support systems designed to protect at-risk communities from VBD threats. Strong interdisciplinary partnerships, protocols, digital infrastructure, and capacity-building initiatives are essential for facilitating the coproduction of robust multisource data sets. This review provides a foundation for researchers and practitioners embarking on data harmonization efforts to (a) better understand the links among environmental degradation, climate change, socioeconomic inequalities, and VBD risk; (b) conduct risk assessments, health impact attribution, and projection studies; and (c) develop robust early warning and response systems. We draw upon best practices in harmonizing data for two well-studied VBDs, dengue and malaria, and provide recommendations for the evolution of research and digital technology to improve data harmonization for VBD risk management.

Climate change, malaria and neglected tropical diseases: a scoping review

Petra Klepac, et al.
Transactions of The Royal Society of Tropical Medicine and Hygiene, Volume 118, Issue 9, September 2024, Pages 561–579

A comprehensive review of studies published from January 2010 to October 2023 found that the effects of climate change on malaria and 20 neglected tropical diseases (NTDs) are highly variable, evolving over time, and difficult to predict globally. Of 511 eligible papers, malaria, dengue, and chikungunya were most frequently studied, while other NTDs were relatively neglected. Only a minority of studies addressed mitigation (34%) or adaptation (5%) strategies, and research was disproportionately focused on countries with lower disease burden and higher healthcare quality, leaving major gaps for high-burden, low-access regions, such as East Africa for leishmaniasis. Overall, coordinated and standardized modelling efforts are urgently needed to clarify how climate change will directly and indirectly affect these diseases worldwide.

Evolutionary dynamics of the successful expansion of pandemic Vibrio parahaemolyticus ST3 in Latin America

Campbell, A.M. et al. – Nature Communications 15, 7828

The evolutionary mechanisms behind global pathogen strain expansions are not well understood, but the spread of the Vibrio parahaemolyticus clone (VpST3) in Latin America offers key insights. This study found that the VpST3 strain was introduced in Latin America earlier than previously thought, adapting successfully to local marine climates through genetic changes that improved resilience and environmental fitness. These findings reveal how this marine pathogen can expand globally by evolving to thrive in distinct climate conditions.

European Climate Risk Assessment: Storyline on Infectious diseases – Chapter 14

Shouro Dasgupta et al.
EEA Report 01/2024
Chapter 14

On a global scale, one of the biggest threats to human health from climate change is the increase in climate-sensitive infectious diseases, driven by rising temperatures, droughts and water scarcity, torrential rains, floods and warming oceans, among other factors. 58% of infectious diseases confronted by humanity worldwide have at some point been aggravated by climate hazards. The impacts on Europe to date have been limited, but there is growing evidence that vector-borne, foodborne and waterborne diseases will increase in the coming decades.

European Climate Risk Assessment: Food production and food security – chapter 6

Frank Dentener et al.
EEA Report 01/2024
Chapter 6

Food production in Europe is intricately influenced by numerous climatic and non climatic factors, including droughts, heatwaves, biodiversity loss and socio-economic dynamics (Bednar-Friedl et al., 2022; Bezner Kerr et al., 2022). Climate change reshapes the conditions suitable for crop production, intensifies risks for weather-related crop/food losses, causes the introduction and establishment of new plant pests, increases the physical and biological risks to animal production systems and shifts the food web and species abundances relevant for fisheries.

Field evaluation of an automated mosquito surveillance system which classifies Aedes and Culex mosquitoes by genus and sex

Field evaluation of an automated mosquito surveillance system which classifies Aedes and Culex mosquitoes by genus and sex
González-Pérez MI et al. – Parasit Vectors. 2024 Mar 1;17(1):97

Mosquito-borne diseases are a major concern for public and veterinary health authorities, highlighting the importance of effective vector surveillance and control programs. Traditional surveillance methods are labor-intensive and do not provide high temporal resolution, which may hinder a full assessment of the risk of mosquito-borne pathogen transmission. Emerging technologies for automated remote mosquito monitoring have the potential to address these limitations; however, few studies have tested the performance of such systems in the field.

The effect of temporal data aggregation to assess the impact of changing temperatures in Europe: an epidemiological modelling study

Joan Ballester et al. – Lancet Regional Health Europe
This paper highlights the use of weekly and monthly data as a viable alternative to daily health records in estimating temperature-related mortality, particularly when access to daily data is restricted. The findings show that while weekly models slightly underestimate cold and heat-related deaths, especially during extreme events, they still provide reliable estimates and can be useful for research and policy-making.
