Soil-transmitted helminth infections affect people who live in areas with poor sanitation and low socioeconomic levels. Ascaris lumbricoides is one of the most frequent parasites worldwide and in México. The General Directorate of Epidemiology reports data related to infections weekly, and this study was based on that. The aim of this study was to analyze the SINAVE data for twenty years (2003-2022) to assess the incidence of ascariasis in the United Mexican States.
We conducted a retrospective observational analysis of ascariasis from January 2003 to December 2022, classifying data by year, age group, state, and gender. A predictive model was used to estimate the new cases until 2030.
From 2003 to 2022, the total number of new cases registered in the whole country decreased by 81.2%. The geographical distribution of the new cases was more pronounced in the Neotropical region of Yucatan, Tabasco, and Chiapas States. Women and infants from 1 to 9 years old exhibited the highest incidence. The prediction model showed that in 2030, there will be an incidence higher than 15,000 new cases in the United Mexican States.
This work indicates that Ascaris infection tends to decrease an is in accordance to our model, and could be related to hand hygiene and the look-down approach during the COVID-19 pandemic.
土壤传播的蠕虫感染影响生活在卫生条件差和社会经济水平低地区的人群。蛔虫是全球及墨西哥最常见的寄生虫之一。流行病学总司每周报告与感染相关的数据，本研究基于这些数据展开。本研究的目的是分析20年（2003 - 2022年）的全国传染病监测系统（SINAVE）数据，以评估墨西哥合众国蛔虫病的发病率。
我们对2003年1月至2022年12月的蛔虫病进行了回顾性观察分析，按年份、年龄组、州和性别对数据进行分类。使用预测模型估计到2030年的新发病例数。
2003年至2022年，全国登记的新发病例总数下降了81.2%。新发病例的地理分布在尤卡坦、塔巴斯科和恰帕斯州的新热带地区更为明显。1至9岁的女性和婴儿发病率最高。预测模型显示，到2030年，墨西哥合众国的发病率将高于15000例新发病例。
这项工作表明蛔虫感染呈下降趋势，与我们的模型一致，这可能与新冠疫情期间的手部卫生和防控措施有关。
