Dengue is a viral disease transmitted by the mosquitoes , which is characterized by fever, myalgia and arthralgia. In some cases, it can be fatal. For many years, dengue fever has been endemic to Mexico; however, few studies have investigated the historical and current extents of dengue fever at the national level or considered the effects of variables such as temperature, precipitation and elevation on its occurrence.
An ecological study was carried out to compare the incidence rates of different types of dengue fever per hundred thousand inhabitants with temperature, precipitation and elevation between 1985 and 2023 in Mexico. The sources of information were the public records of the Ministry of Health and the National Meteorological Service. Multiple linear regression analysis was performed with Pearson and Spearman correlation coefficients at an alpha of <0.05.
The global linear regression presented an R of 0.68 between the mean temperature and the cases of haemorrhagic dengue/severe/with warning signs. The degree of rainfall was not strongly correlated with the incidence rate, except in the eastern part of the country, where average temperature was also strongly correlated with the incidence rate. Nonsevere/classic dengue was most common from 1501 to 2000 m elevation, whereas severe forms of the disease were more prevalent at elevations greater than 2000 m.
登革热是一种由蚊子传播的病毒性疾病，其特征为发热、肌痛和关节痛。在某些情况下，它可能是致命的。多年来，登革热在墨西哥一直呈地方流行状态；然而，很少有研究在国家层面调查登革热的历史和当前流行程度，或考虑温度、降水和海拔等变量对其发生的影响。
开展了一项生态学研究，以比较1985年至2023年墨西哥每十万居民中不同类型登革热的发病率与温度、降水和海拔之间的关系。信息来源是卫生部和国家气象局的公共记录。采用Pearson和Spearman相关系数进行多元线性回归分析，显著性水平α<0.05。
全球线性回归显示，平均温度与出血性登革热/重症/有警示体征的病例之间的R值为0.68。降雨程度与发病率的相关性不强，除了该国东部地区，该地区平均温度也与发病率密切相关。非重症/典型登革热在海拔1501至2000米处最为常见，而该疾病的重症形式在海拔高于2000米处更为普遍。
