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.

How to avoid having mosquitoes in your house

Mosquitoes can inhabit a multitude of spaces and environments as long as there is water. Mosquitoes need water to reproduce.

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.
