Uncovering temperature sensitivity of West Nile virus transmission: Novel computational approaches to mosquito-pathogen trait responses

Heidecke et al. – PLOS Computational Biology, Volume 19, e1012866

This study introduces a computational framework to assess temperature sensitivity in mosquito-pathogen interactions, focusing on West Nile virus (WNV). Using experimental data across 15 mosquito species, the authors estimate temperature response functions for key traits influencing WNV transmission. They find an optimal transmission temperature around 24°C for Culex species and highlight key areas for future research to improve transmission models under climate change.

Short-term effect of temperature and precipitation on the incidence of West Nile Neuroinvasive Disease in Europe: a multi-country case-crossover analysis

Moirano, Giovenale et al. – The Lancet Regional Health – Europe, Volume 48, 101149

In recent years, Europe has experienced several outbreaks of West Nile Virus (WNV), a mosquito-borne pathogen. This study aims to quantify the impact of weekly mean temperature and cumulative precipitation on human cases of West Nile Neuroinvasive Disease (WNND), to assess the feasibility of climate-informed early warning systems for severe forms of WNV infection.

Heat stress and the labour force

Dasgupta, S., Robinson, E.J.Z., Shayegh, S. et al. – Nat Rev Earth Environ 5, 859–872,

Heat stress affects the health of workers through physiological and behavioural responses, in turn, affecting the labour force through impacts on labour supply, labour productivity and labour capacity. In this Review, we explore the extent to which heat stress affects the labour force and discuss the corresponding occupational health and economic impacts. DOI: 10.1038/s43017-024-00606-1

Residual Longevity of Recaptured Sterile Mosquitoes as a Tool to Understand Field Performance and Reveal Quality.

Balatsos, G et al. – Insects 2024, 15, 826

The current study focused on understanding the longevity and frailty of sterile, non-sterile, and wild male mosquitoes subjected to different treatments, using the novel captive cohort method. Key findings include that marking mosquitoes, following IAEA protocols, had an insignificant effect on longevity under controlled conditions, and that sterilization had no negative effect on male longevity.

Mitigating the Threat of Invasive Mosquito Species Expansion: A Comprehensive Entomological Surveillance Study on Kastellorizo, a Remote Greek Island

Bisia, M. et al. – Insects 2024, 15, 724

This paper details a study on Kastellorizo island that tracked mosquito species, including the invasive Asian tiger mosquito, using KAP surveys, mosquito traps, and species identification to assess mosquito prevalence and community preparedness. The research revealed the presence of disease-carrying mosquito species and highlighted the need for increased public education and community involvement in mosquito monitoring to develop effective control strategies in isolated areas.

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.

Human–Environment Interactions Shape Mosquito Seasonal Population Dynamics

Blanco-Sierra, L. et al. – Insects 2024, 15(7), 527

This study investigates the factors influencing local populations of Aedes albopictus, a highly invasive mosquito species known for its role in spreading vector-borne diseases. Aimed at enhancing vector control effectiveness, the research focused on understanding the interplay between meteorological elements, human activity, and pest management efforts in determining mosquito abundance at local scales.

A climatic suitability indicator to support Leishmania infantum surveillance in Europe: a modelling study

A climatic suitability indicator to support Leishmania infantum surveillance in Europe: a modelling study Carvalho, Bruno M. et al. – The Lancet Regional Health – Europe, Volume 43, 100971

Leishmaniases are neglected diseases transmitted by sand flies. They disproportionately affect vulnerable groups globally. Understanding the relationship between climate and disease transmission allows the development of relevant decision-support tools for public health policy and surveillance. The aim of this modelling study was to develop an indicator that tracks climatic suitability for Leishmania infantum transmission in Europe at the subnational level.

The 2024 Europe report of the Lancet Countdown on health and climate change: unprecedented warming demands unprecedented action

Kim Robin van Daalen et al. – The Lancet Public Health, Volume 9, Issue 7

In 2023, record-breaking temperatures were recorded globally, with Europe warming at twice the global average, posing severe health risks. The Lancet Countdown in Europe, established in 2021, tracks health impacts of climate change to push for urgent climate-responsive actions. The 2023 report, now expanded to 42 indicators, highlights the worsening health impacts, Europe’s delayed climate action, and emphasizes the need to address inequality and justice in climate responsibility and health risks.

The global health community at international climate change negotiations

Kim Robin van Daalen et al. – Crossref

This article highlights the growing involvement of the global health community in international climate change negotiations, particularly at COP28, which saw the largest-ever turnout of health professionals. It emphasizes how health actors are increasingly influential, with health goals integrated into 91% of Nationally Determined Contributions (NDCs) and COP28 featuring over 200 health-related events, significant funding commitments, and the endorsement of a political declaration on climate and health by 149 countries.
