以前的研究表明，与利什曼原虫传播相关的媒介分布的变化可能与气候变化有关。然而，这些生态变化对人类健康的潜在影响需要在各种流行人群中进一步确定，在这些人群中，利什曼病带来了很大的疾病负担，例如在哥伦比亚东北部。在此，我们报告了1985-2002年期间厄尔尼诺南方涛动气候波动对哥伦比亚东北部两个省发生利什曼病病例的影响。在此期间，我们发现在厄尔尼诺期间，利什曼病病例增加，而在拉尼娜期间，利什曼病病例减少。这些初步数据显示了气候变化如何影响哥伦比亚东北部利什曼病的发生，并有助于越来越多的证据表明媒介传播疾病的发生率与天气条件的年度变化有关。
Previous studies have shown that variation in the distribution of vectors associated to the transmission of Leishmania species may be related to climatic changes. However, the potential implications of these ecological changes in human health need to be further defined in various endemic populations where leishmaniasis carries a substantial burden of disease such as in Northeastern Colombia. Herein, we report the impact of El Nino Southern Oscillation climatic fluctuations during 1985-2002 in the occurrence of cases of leishmaniasis in two northeastern provinces of Colombia. During this period, we identified that during El Nino, cases of leishmaniasis increased, whereas during La Nina phases, leishmaniasis cases decreased. This preliminary data show how climatic changes influence the occurrence of leishmaniasis in northeastern Colombia and contributes to the growing body of evidence that shows that the incidence of vector-borne diseases is associated with annual changes in weather conditions.
