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.

Impact of climate and Aedes albopictus establishment on dengue and chikungunya outbreaks in Europe: a time-to-event analysis

Farooq, Zia et al. – The Lancet Planetary Health, Volume 9, Issue 5, e374 – e383

The rapid spread of the Asian tiger mosquito (Aedes albopictus) poses a notable public health threat in Europe due to its ability to transmit tropical diseases such as dengue and chikungunya. This study aims to quantify the underlying drivers facilitating and accelerating Europe’s transition from sporadic arbovirus outbreaks to Aedes-borne disease endemicity, focusing on dengue and chikungunya outbreaks.

Modelling the impact of climate and the environment on the spatiotemporal dynamics of Lyme borreliosis in Germany

Batista, Martín Lotto et al.
eBioMedicine, Volume 115, 105701

This study used spatiotemporal Bayesian modeling to analyze the impact of climate and environmental factors on Lyme borreliosis (LB) dynamics in Germany. The research found that precipitation, temperature, green spaces, and forest cover positively influenced LB incidence, while human population density had a negative impact. The study also identified increasing trends in LB risk, particularly in northern regions, and highlighted the role of climate in shaping LB distribution and transmission.

The 2024 report of the Lancet Countdown on health and climate change: facing record-breaking threats from delayed action

Marina Romanello, Maria Walawender, Shih-Che Hsu, Annalyse Moskeland, Yasna Palmeiro-Silva, Daniel Scamman et al. – The Lancet Public Health, Volume 9, Issue 7, November 2024

The 2024 Lancet Countdown report, produced by 122 researchers from UN agencies and academic institutions, delivers the most concerning findings in eight years of monitoring the health–climate nexus. Despite hopes from the 2015 Paris Agreement, global warming has nearly reached the 1.5°C limit, with record surface temperatures in 2023 and 2024 driving escalating risks to lives and livelihoods worldwide.

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.

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.

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.

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.
