Malaria and dengue are vector-borne endemic diseases in the low-lying regions of Colombia. Outbreaks of both diseases appear during the occurrence of El Niño in the tropical Pacific. We present updated data confirming the relation, which are explained by the increase in temperature. Malaria shows an increasing trend, of which climate change cannot be disregarded. The migration of over 1?200?000 Venezuelans hiding away from the internal crisis has complicated the situation. Further research is needed to pinpoint the linkages between vector-borne diseases and climate variability, but also with current and future impacts of climate change, and alarming deforestation rates of Colombia. The public health system has been impacted by the COVID-19 pandemic, especially in the poorest and most vulnerable regions (Pacific coast, Amazon and Orinoco). This note constitutes a call to Colombia's public health system to maintain vector and water-borne diseases services, which cannot become neglected amid the COVID-19 pandemic.

伴随的疟疾，登革热和COVID-19：对哥伦比亚公共卫生系统而言是一项非凡的挑战。

疟疾和登革热是哥伦比亚低洼地区的媒介传播地方病。两种疾病的暴发都发生在热带太平洋的厄尔尼诺现象期间。我们提供了确认该关系的更新数据，这可以通过温度升高来解释。疟疾呈上升趋势，其中气候变化不可忽视。躲避内部危机的1200到200000多名委内瑞拉人的迁移使局势复杂化。需要进行进一步的研究，以查明病媒传播疾病与气候变异之间的联系，还要查明气候变化的当前和未来影响，以及令人震惊的哥伦比亚森林砍伐率。公共卫生系统受到了COVID-19大流行的影响，特别是在最贫穷和最脆弱的地区（太平洋海岸，亚马逊和奥里诺科）。
