Abstract

Background: This systematic review investigates the relationship between malaria incidence, climate variables, and deforestation in Colombia, Latin America, and the Caribbean from 2000 to 2020. Malaria, a significant public health issue in these regions, is influenced by ecological factors including climatic conditions and environmental changes, such as deforestation.

Methods: The review employs a comprehensive search strategy across PubMed, Web of Science, Embase, Scopus, Cochrane, and Scielo databases. It applies strict inclusion and exclusion criteria to ensure the relevance and quality of selected studies, focusing on analysing the relationship between climate variables, deforestation, and malaria incidence.

Results: Twenty-four articles were included in this review, fourteen of which assessed the relationship between climatic variables and malaria and ten between deforestation and malaria. The analysis reveals a nuanced understanding of malaria dynamics. A significant finding is the seasonal effect of climatic variables on malaria incidence. The study notes that increased rainfall is positively correlated with malaria incidence. Similarly, warmer temperatures are associated with increased malaria risks, and malaria rates can change by 10% to 80% for every degree of temperature increase, after adjusting for altitude. The impact of deforestation on malaria is complex, with positive and negative correlations observed, depending on the remaining forest cover.

Conclusions: The review highlights the multifaceted nature of malaria transmission, emphasizing the need for integrated approaches that consider both environmental and health perspectives. It underscores the importance of understanding the complex relationships between malaria incidence, climate variables, and deforestation.

2000 年至 2020 年哥伦比亚、拉丁美洲和加勒比地区疟疾、气候变量与森林砍伐的关系：系统综述。

背景：本系统综述调查了 2000 年至 2020 年哥伦比亚、拉丁美洲和加勒比地区疟疾发病率、气候变量和森林砍伐之间的关系。疟疾是这些地区的一个重要公共卫生问题，受到包括气候条件和环境变化（如森林砍伐）在内的生态因素的影响：方法：本综述在 PubMed、Web of Science、Embase、Scopus、Cochrane 和 Scielo 数据库中采用了全面的检索策略。研究采用了严格的纳入和排除标准，以确保所选研究的相关性和质量，重点分析气候变量、森林砍伐和疟疾发病率之间的关系：本综述收录了 24 篇文章，其中 14 篇评估了气候变量与疟疾之间的关系，10 篇评估了森林砍伐与疟疾之间的关系。分析显示了对疟疾动态的细微理解。一个重要发现是气候变量对疟疾发病率的季节性影响。研究指出，降雨量增加与疟疾发病率呈正相关。同样，气温升高也与疟疾风险增加有关，气温每升高一度，疟疾发病率就会增加 10%到 80%（根据海拔高度进行调整）。砍伐森林对疟疾的影响非常复杂，根据剩余森林覆盖率的不同，可以观察到正相关和负相关关系：本综述突出了疟疾传播的多面性，强调需要从环境和健康两个角度综合考虑。它强调了了解疟疾发病率、气候变量和森林砍伐之间复杂关系的重要性。

期刊介绍： Malaria Journal is aimed at the scientific community interested in malaria in its broadest sense. It is the only journal that publishes exclusively articles on malaria and, as such, it aims to bring together knowledge from the different specialities involved in this very broad discipline, from the bench to the bedside and to the field.
