coronavirus disease 2019 (COVID-19) was declared a pandemic in March 2020, and most patients recover within a few days or weeks. However, some patients suffer from long COVID, which is characterized by prolonged symptoms of varying severity. Given the importance of the mining sector to the South African economy, it is critical to comprehend the impact of long COVID on the mining sector.
we carried out a cross-sectional study that included data extraction from participant medical records and responses to study questionnaires. We used unique identifiers to anonymize participant information and match data from medical records to participant questionnaires.
data from 239 medical records and 362 questionnaires were provided by employees from three mines. About 7% of people with COVID-19 were identified as having long COVID. In addition, there was no difference in productivity between people with and without long COVID.
our findings are not generalizable to the entire mining sector due to the limited number of participants who provided data. Additional studies that include a larger sample size are required to obtain more robust estimates of the prevalence of long COVID in the mining industry and explore potential effects of various treatment interventions for patients with long COVID.
2019年冠状病毒病(COVID-19)于2020年3月被宣布为大流行病,大多数患者在几天或几周内康复。然而,一些患者患有长期新冠后遗症,其特征是症状持续时间延长且严重程度各异。鉴于采矿业对南非经济的重要性,了解长期新冠后遗症对采矿业的影响至关重要。
我们开展了一项横断面研究,包括从参与者的医疗记录中提取数据以及对研究问卷的回答。我们使用唯一标识符对参与者信息进行匿名处理,并将医疗记录中的数据与参与者问卷进行匹配。
来自三个矿山的员工提供了239份医疗记录和362份问卷的数据。约7%的COVID-19患者被确定患有长期新冠后遗症。此外,有长期新冠后遗症和没有长期新冠后遗症的人的生产力没有差异。
由于提供数据的参与者数量有限,我们的研究结果不能推广到整个采矿业。需要开展更多样本量更大的研究,以更准确地估计采矿业中长新冠后遗症的患病率,并探索针对长新冠后遗症患者的各种治疗干预措施的潜在效果。
