The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the coronavirus disease (COVID-19), a highly contagious infectious disease that has caused many deaths worldwide. Despite global efforts, it continues to cause great losses, and leaving multiple unknowns that we must resolve in order to face the pandemic more effectively. One of the questions that has arisen recently is what happens, after recovering from COVID-19. For this reason, the objective of this study is to identify the risk of presenting persistent symptoms in recovered from COVID-19. This case-control study was conducted in one state of Mexico. Initially the data were obtained from the participants, through a questionnaire about symptoms that they had at the moment of the interview. Initially were captured the collected data, to make a dataset. After the pre-processed using the R project tool to eliminate outliers or missing data. Obtained finally a total of 219 participants, 141 recovered and 78 controls. It was used confidence level of 90% and a margin of error of 7%. From results it was obtained that all symptoms have an associated risk in those recovered. The relative risk of the selected symptoms in the recovered patients goes from 3 to 22 times, being infinite for the case of dyspnea, due to the fact that there is no control that presents this symptom at the moment of the interview, followed by the nausea and the anosmia with a RR of 8.5. Therefore, public health strategies must be rethought, to treat or rehabilitate, avoiding chronic problems in patients recovered from COVID-19.
严重急性呼吸综合征冠状病毒 2（SARS-CoV-2）是导致冠状病毒病（COVID-19）的罪魁祸首，这是一种高度传染性的传染病，已在全球范围内造成许多人死亡。尽管全球都在努力，但它仍在继续造成巨大损失，并留下了许多我们必须解决的未知数，以便更有效地应对这一大流行病。最近出现的一个问题是，从 COVID-19 中康复后会发生什么。出于这个原因，本研究的目的是确定从 COVID-19 中康复后出现持续症状的风险。这项病例对照研究在墨西哥的一个州进行。最初，通过一份关于他们在接受采访时所出现的症状的问卷，从参与者那里获得数据。最初收集了收集到的数据，以制作一个数据集。然后使用 R 项目工具进行预处理，以消除异常值或缺失数据。最终获得了总共 219 名参与者，141 名康复者和 78 名对照组。置信水平为 90%，误差幅度为 7%。结果表明，所有症状在康复者中都存在相关风险。选定症状在康复患者中的相对风险从 3 到 22 倍不等，由于在接受采访时没有对照组出现呼吸困难症状，因此呼吸困难的相对风险为无限，其次是恶心和嗅觉丧失，相对风险为 8.5。因此，必须重新思考公共卫生策略，以治疗或康复患者，避免 COVID-19 康复患者出现慢性问题。
